You are so underrated! Great content. It amazes me how fast you are. I am prepping for the GMAT Focus right now, but honestly I feel like I still have a long way to go!
This video has been so helpful. It gave me the confidence to give mocks and after watching this video, I started doing RC without making notes which really helped me. Thanks so much, your videos are brilliant! The ease with which you solve questions is commendable.
Thank you for making this video. It really helped me understand how different my approach is and what areas I need to work on. I learnt a lot from this, so thank you!
Your thought process in quant to fastly translate words to maths and your ability to simplify hard questions is insane. I am taking my GMAT tomorrow and I learnt a lot from this. Hope I can score 700+ tomorrow using your strategies and patterns. Only big issue for me is I'm way too slow when it comes to CR and in the Verbal section overall, as I am unable to scan CR and RC passages. But I took a lot of notes from this video. Thank you it was very insightful!
Im sure mbas at harvard are chill 😉 (wouldn't know never did one nor planned to 🤣) Though on a more serious point gmat is insanity as a test for an mba. I would NOT be a good executive. But hopefully have a confirmed gmat wr out soon lol. Utterly stupid. Why isn't it literally a mix of entrepreneur case studies, executive case studies and a public speaking recorded section (awa but spoken) with a persuasive mark. View it as an obstacle that will help your mental maths for life at least lol ((used to help writing but sc gone which while horrific was useful 🙄)
After watching this a couple of times and understanding how well you think, i've gauged that in the 4 step hierarchy of competence, you're at the highest level, i.e. unconscious competence. The small things like how 20,000/1.25 is (20,000/5)*4 which make it so much easier to solve is beautifully simple. Brilliant stuff. Looking forward to getting more value from you. One suggestion of a topic that I would appreciate if covered - How to practice official guide questions and practically identify and improve your weaknesses in Quant. 4 step hierarchy of competence for reference: 4] Unconscious Incompetence - Wrong Intuition 3] Conscious Incompetence - Wrong Analysis 2] Conscious Competence - Right Analysis 1] Unconscious Competence - Right Intuition
Thanks for making this Daniel, I just started my journey on GMAT and this was refreshing to see the way you tackled these problems. Could you possibly elaborate more on what you wrote In the description? (Techniques for all “official” topics?) Either way, you are a great resource. Cheers!
Hey there! Since you mentioned to share if anyone comes across a more efficient method for solving questions, so I wanted to pass along one I found while prepping for the GMAT. In question 3 (average speed), there's a quicker way to solve it when the distance remains constant. Specifically, if someone travels the same distance at two different speeds, you can find the average speed using this formula: Average speed = 2ab / (a + b) Here, "a" and "b" are the two different speeds. This method is especially useful for Data Sufficiency questions and entails one important point that when the distance remains unchanged, we can find the average speed without the actual need of knowing the distance or even time for that matter. For question 3, applying the formula would give: Average speed = 2ab / (a + b) = 2(30)(60) / (30 + 60) = 3600 / 90 = 40 i.e., option B.
It does, I won't lie. But you'd be surprised. Many native speakers get screwed over by colloquialisms and I myself found SC hardest by far. My guide, coming this year but can't be rushed I'm afraid as it is HARD to make the gmat as simple as I'm trying to, shouldn't benefit fluent or non fluent speakers
working on it. I'm almost healthy and have actually started typing away. videos in future will include one ""like this"" for focus but not done in 90 mins for a students request! about 2 weeks from recovered from a nearly 2 yr illness, THEN I get to do it finally:')
Your advice is spot on. I have been preparing for GMAT for the past month. I did get 550 on my first-ever official mock without any preparation. Then I started preparing from Manhattan Prep Materials and solving some questions on GmatClub. Then, I took the GMAT Club mock. Pretty I soon figured I was doing the problems in the old algebra way or the method I learned earlier, which is just consuming time and created panic in my mind. I soon started to find efficient techniques to replace my inefficient ones and came across your videos. It has been challenging since RUclips is filled with videos of people bragging about their "700+ scores in X months preparation strategy" Very few are actually talking about the real thing i.e. "techniques". One question I really wanted to ask is about the "source." Apart from the Internet, do you suggest any book or website in particular where most of these techniques are given, hence cutting down the preparation time even further?
Appreciated. I'm really sorry to say, while it may exist, I didn't find it. That's what this channel will become. Should've been already. Blame some bad luck 🤣 what i can recommend though is methodically search for the broadest techniques first. By which i mean, personally, (biased) my translation method as a starter for all questions. Then methodically go through a bunch of QUESTIONS, not materials, 500-600 and 600-700, official, on gmat club (not 700-800 until crushing all prior (hint: your score is sick once thats done, screw the 700-800 with a few exceptions for the extra knowledge but 500-600 and 600-700 90% of time then 700-800 just scanning through for new knowledge not solving questions really. Just not a good way of learning. Anyway! So you have a basic overall question approach down for all questions via practicing because obviously a high worth skill (every question...) (*cough* translation*cough*). That solves....a lot. Then you go through these official questions seeing if you can solve them. 500-600 first. Really really should be fast, all, before moving on. Wont be at all at first. That way you identify your good methods, lacking knowledge, and lacking methods. So you search around on specific question types you're slow at or cant do (say open 30 500-600 'divisibility' questions - should cover all knowledge for that level. Manually working through topic by topic 500-600. You will find ones you cant do. Or are slow or find hard. Those you know are bloody easy. You're missing knowledge or technique. So you search until you find one reliable technique you like. And you pay attention to how easy those questions are now. Thats a LONG process but pretty simple and efficient by definition. Why learn techniques for ones you're doing well on? Now 600-700. Immediately youll notice vastly better at these. But holes. New knowledge and method gaps. So repeat. Methodical. Long. But then you're 99% done. Don't rush this bit it's LONG. 700-800 you dont solve yet. You do the same: divisibility, OG questions only, 30 700-800. You look for new missing KNOWLEDGE not just hard questions. Will be obvious. One example being modulus: 700-800 suddenly you have 2-3 modulus signs and all your methods break. Learn the knowledge when found. This shouldn't take anywhere near as long as 600-700. Now, if you want practice doing hard questions you can do some 700-800 knowing you're not missing knowledge. Otherwise you're mixing difficulty with missing knowledge and they are not the same thing. Difficulty takes years and years to meaningfully start crushing them. Knowledge takes a few weeks. Hope difference is obvious. Truthfully if you are able to crush the 500-700s now faster than the time usually you'll have time to solve the hard ones, or some of them. But they truly don't matter like the easy ones. Very counter intuitive but just think of your score as rising up to a level and trying to survive there. All easy and medium correct, some hard right, some wrong, you've done Damn well. 760 type well on old test. Bit better on hards at cost of 1-2 easy/med? 700. Scoring dumb. People worry way too much about hard qs. Get the knowledge and that includes techniques. That gets you easy and med correct and speed and knowledge so you have time and knowledge to solve the hard ones. Which don't matter you're now 760-790 deciding. (800 is all right, 790 I got 9 wrong once...)
I hope that makes sense and provides some structure? Very easy to search for methods on a particular question, gnat club, youtube, internet generally etc. Thats my style of teaching for what it's worth anyway. It's literally all your prep from 0 to fully ready outlined in, by definition, the most efficient you'll get outside of me finishing this channel or getting a damn good tutor (RARE)
@nbrahmareddy7690 afraid all focus is on building this channel atm. Watch this space in 2023. It won't be quick, I'm sorry, but I want to make full guides explaining how I got 800 in half time and so that you can do similar. Which is difficult to make but will be worth it!
Hey! I need help understanding how you solve question 16 in quant section. I understand how you got 2^(n/2) * (n/2)! but not sure how you concluded from there that the smallest prime factor had to be greater than 50. Thanks for your help in explaining! Awesome video
Understandable - weird q: Imagine an even number: add 1. Not divisible by 2. Imagine a number divisible by 5. Add 1. Same obvious result. We know is divisible by all primes up to 50 cos literally has them as factors, so add 1 and can't be divisible by any of them. Does that help?
A) good luck ofc. But B) afraid I don't know you but what I can say is 2 things: 1) Almost anyone can go to 700+ with enough (sometimes many many hours prep) 2) Depending on usage and goals and reasons, think about if taking a year out to go somewhere better is worth it - wouldn't just be gmatting ofc. People always rushing everything 🙄
@@dans1129 Do you recommend spending more time reading the passage in the beginning or reading more quickly to map out the tone of the passage then refer back to the passage when needed while answering questions? I ask because RC tends to eat a lot of the time i have for verbal. Thanks!
The above comment Zach was replying to which I'd rather keep separate, so have deleted my original reply on that. Anyway, I sort of recommend a mix. Read the first question (not the options just the question) first. Then read the passage such that you understand it and can sort of remember where each bit was so you can find them quickly later. So overall I tend to recommend more thorough reading at first than less, but not ULTRA thorough; just enough to understand the passage and know what each bit was about.
Hence, me in the video is not even me following my own advice (as I should've been more thorough rather than skim reading and it could have cost me). But it was a while ago and I'm much better at the gmat now. New videos coming soon, of much, much higher quality.
Sorry I know I keep failing to deliver- answer is genuinely soon (this month). Moving right now and essentially new videos will come as my health improves which will start rapidly having moved. Incredibly grateful for the support despite no uploads and has convinced me to really follow this and that I have something of value to share
3 years may be overkill but approve of keenness 🤣 would argue general career progression or uni focus or skill learning more important for next 2 minimum 😉 but yes leaving many many months to do 1 topic a week by doing 30min-1hr a day is how people go from 500 to 750 At risk of sounding insufferable, my prep was my degree and life of loving debates so lucked out into only needing sc prep. But that means technically I did years of prep without knowing it (For anyone curious this led to my first 'blind what is gmat?' official mock test score being 770 which is why a course takes me so long - never mapped one out carefully for myself nor learnt best methods systematically -- course design now is via coming up with my best methods now that I choose/create then check extensively online if anyone has a better way ((they often do))
Don't want to sound like I'm making excuses - just explaining truthfully without tmi. Moving right now, finished tomorrow; this will allow my health (which has been the reason for lack of uploads) to start improving finally. With that and the fact it's part of my current 'important' and job priorities in mind, I'd be very disappointed if not this month. Plan is for full course done by end of year - GMAT focus course easier (no SC) with new additions based on feedback and new ideas throughout 2024 and ofc tbh a full revision expected in future (2025) as I learn RUclips and new GMAT methods. If my health improves as expected this will get done. If not I don't have a choice in the matter unfortunately 🤷♂️ Hopefully people can tell l care and want to be helping and can believe me not being able to so far is just as frustrating for me as anyone else!
quantitative question 2 messed me up. Obviously if there is a higher percent in the profit than the loss, the total gain will be profit but you put that it would be a loss and got the question correct. maybe because this is british but if the dealer makes a 5000 profit from the first car and loses 4000 on the second car, how can the total be a loss?
It's a sneaky one. Translation really shines here as reading it to 'go with your gut' will steer you wrong. 1) Meant respectfully but maths in the UK is the same as Math in the US so don't worry all answers should line up! 2) The sneaky reason for loss comes out in the maths: he made 25% profit on a cheap car and lost 20% on an expensive one. Hence he lost money overall. Also he gained 4000 on first and lost 5000 on second not vice versa Hope this helps
You can't do it yet. Nor do you need to. You need to learn how to do it but about 30% slower (I had loads of time left) and with some mistakes. You don't need 800; it is an unbelievably rare score. You need 730 for the very best courses in the world. And I have scored 770 with 6 mistakes before. I haven't scored 730 but would imagine it allows about 10 mistakes, as long as they are on hard questions. You do NOT want to get the easy questions wrong however. Proper guides coming soon! (Within 2023)
@@thetutordl Hopefully sooner :D Best way to do guides in my opinion would just be to a guide for the main topics - and try include official questions with each topic and sub-topic taught - this is the best way to reinforce the teaching. would also help to provide 2-3 different methods to solve questions so that students can pick which seems more intuitive to them
Dear all, please read description prior to get the most out of the video! Additionally I answer every question written so feel free to enquire :) Also I'm sorry about any ads you get that are ridiculous I tried to minimise it without the algorithm crushing me but a new change means I've lost a lot of control on that end :( While I of course woukd never use such tools, everyone knows adblock on Windows but fewer on android know of youtube revanced. If researching just make sure you stick to github and the main project page before downloading anything as viruses rife from fake sites. I've heard it allows youtube to continue to play when you put your phone to sleep and auto skips all adds so understand why some use it! Iphone/mac no idea sorry :( Finally, anyone who made it here: I assume I sound English? Is my speaking and tone clear to understand? Understand audio is the most important part about new videos and luckily have had relatively good reviews of my voice 😂 but happy to work on anything needed. (Please take into account I truly was doing the exam so explanations etc. Won't be ideal - hopefully forgivable 😂) Best, Daniel
Linkedin search Daniel Lauber gmat tutor or Gmail daniellauber6: please note I'm actually at work right now both writing a post for this channel and making my first proper videos:) additionally am still very much recovering from severe health issues last year so while I love to help people too much please do be aware any help elsewhere takes away from my limited energy at the moment to finally do this channel:) ((was so ill not even tutoring:( )
Thank you so much for this amazing content. I'm preparing to take the GMAT exam in July, could you please do a personal tutoring with me? I'd really be grateful (ofcourse I know it won't be free, lol)
I truly wish I could. I've gone quiet because I'm not a complainer and it got silly but truthfully the amount of health problems and then crime from family no less the world has chucked my way is so obscene that for the first time in 6 years I can't even tutor (physically as in place to live sort out all other stuff) which since these are all random 'crappy' videos for my students is hopefully obviously something I love
Not to mention I HATE making promises and then failing; odds of this stuff I swear! Frustrated can't make these videos, tutor and on top launch my ai startup which has been 8000 hours in the making and is 200 from launch. Not whining so much as horribly frustrated
I can however, if you give me time to find somewhere to live (don't ask 🤣), give my number if you email me at daniellauber6@gmail.com and have a long chat sometime say in a week? As small as that sounds, I do believe it's likely to make your prep vastly more efficient after :) No charge for that - despite all this I did make it quite high in the tutoring world and have made some very good investments so luckily that is one thing I don't have to worry about ((not rich lol just cash buy a 1 bed flat in London levels which is far from destitute and yes I'm proud of doing so in 5yrs of tutoring following by going on 2yrs of stolen life hopefully coming to an end! (28 now so not that ancient yet lol). All I can say is this channel is important to me for the original reason but now also for US contacts for my startup who will hopefully trust me if I make outrageous claims like "would you like $30k a year? 100pg doc, odd button click, legal or I'm off to prison for life on 10000 misdemeanors 🤣 and obviously commission but otherwise don't want a thing from you." sounds awfully suspicious I know but....8000hrs and several years and means the states will FINALLY let me in after first 2 years building in UK. All that is to say, 100,000 subs who know I'm smart and tend to like helping people might mean a couple thousand US contacts to then ofc spread like wildfire when I make good. Therefore this channel IS being finished and assuming no more ridiculous infernos life should return in a couple of months here. ....sorry ranted a bit at you. Frustrated would be my word; finally figured out how to use my gift to give and 2yrs of BS says no 🤣 (not a saint, chasing dopamine like everyone else and for the record fully intend to become a billionaire with my startup and if only I'd recorded the 800 in 62 mins might seem more plausible 😉 pending no more infernos. those i cannot predict. Why screw you all over with infernos on me though God? Seems mean. 🤣
I will be honest and say a life of reading books when young and scientific papers probably helps. However, my overall technique for reading is to skim the 'obvious' bits and really only zoom in on the confusing harder bits for RC and CR. Given a passage in RC I probably spend 50% of the time on 10% of the sentences as they're the worst ones. In SC which is gone in focus (so true advice if sc is the problem is take focus!), I do similar: I literally 'cross out' irrelevant words and sections of the sentence and zoom in on things like 'between' or 'not only' or 'which' that are all trigger words. Hope that helps a little? Overall advice if speed is issue is ask questions like this and research ways of speeding up, then practice practice practice with speed in mind but NOT speed rushing to the point of being wrong. Just try to truly get answers 100% right as fast as possible over and over with tactics like those above being practiced and you will speed up :)
Thanks for the video but i have maybe a dumb question about q9 - n could equal 1 which means the product would be 0, would the remainder be 0 or -24? If the latter, then shouldn’t the answer be insufficient? Thanks
@@thetutordl Hello - I am in the process of watching the video, and I am nowhere near your level and just starting my journey with this, but I think the point trying to be made above (linking to your point in the video about `finding the exception`) is that the exception in this case could be n = 1. This is not divisible by either 2 or 3, and gives 0, so therefore both statements aren`t sufficient as more specific information will be required on the nature on `n`? This is me instinctively assuming that 0 isn`t a valid remainder, however.
Didn't fully, just gist and frankly bad technique. Biggest tip and please listen to this seriously: Easy wrong due to taking 10 seconds instead of 20 saves you 10 seconds at the cost of 50 points. Very hard right because spent 5mins not 4 maybe 10 points? Imagine your score is snakes and ladders and you want to Finish high. Contrary to expectations AND time taken/saved I've gotten 780 with 11 wrong and 760 with 5 wrong. 760 was 2 easy Qs silly mistakes early knocking me so far down I wasn't given hard Qs in time to recover. Master 500-600, spend time and get 600-700 right then fuck all 700-800; you climb up snd have small snakes down for the wrong hards
See what score you get. But google your wrong answers to see if 5-6, 6-7 or 7-8. Any easy wrong RIP score but know that's an area you lack knowledge. Go study it.
P.s. If I were to upload full guides for free better than anywhere found elsewhere (whether they be paid or free, how would you find it last annoying for me to monetise? 1) Short skippable adds.at start 2).Sponsors.at end for products I truly reoommend/use myself such as audible? 3) patreon etc.? 4).Affiliate links to e.g. amzon in description where I get 2% of whatever you spend? I want to keep this free forever but if it does get popular if I can monetize it I can put in more effort. I only make such claims as I'm working on my methods to get 800 in half time (31Q.32.5V) which SURELY must generalise!
@@srilanka739 interesting. That was going to be my final option after a genuine request to share the channel to at least 5 people who will take the GMAT 1 day For the record: my income is of course tutoring. Now a successful RUclips channel would of course allow me to increase my hourly rate due to cutting down the hours each student needs. But truthfully, as much as I love tutoring and will do a bit of it forever I'd far rather help far more people who can't afford tutoring. Hence the YT channel plan over the next 2 years. And yes, the success of that does depend on whether I'm as good as I think I am/can be; time will tell! I don't actually teach the GMAT yet because I am not qualified to. Yes I scored 800 but that doesn't mean I can explain it to others. Hence the huge amount of time/thought put into the new course and why I can't rush it :( (And yes, that was a subtle jab at many other so called GMAT 'tutors' who scored 760 and decided that makes them a tutor)
I used zoom with screen sharing and recording of my screen to make the video. Not sure if you can record without screen sharing - probably can - will check thanks
I will soon; this channel is more as a small resource to help current students that I teach at the moment, but I plan to make proper guides in future, all of which will be available here on RUclips
maths at Cambridge kinda cheating ahaha. and tutor... but yes OG ONLY and almost none above 600-700 diff. and all that matters is topic by topic and search for the easiest questions you can't do...more soon :)
7:07 Why in question nº7, when its saying that the average of 5 different positive integers is at least 30, the 1st statement assumes that each of the integers is a multiple of 10. But what ensure that the numbers wont be like: 10,10,10,10,10. They are all multiple of 10 but the main sentence about the average being at least 30 is not ensured in this. Am I right?
Hello, The question at 32:47 of your youtube video if you put x=1 ( as x is positive) in all three options all three options do not satisfy the condition when x=1 Then the answer should be none
Ah interesting point. You are correct if x was 1 none would be valid. But the question was if x was positive which COULD be valid? I.e. if x is some positive number that we choose which of these has a chance of working for some choices of x
Hey I just wanted to ask one doubt . In the question where you are supposed to take the mean of 5 different integers and the first statement is saying 1) every integer is a multiple of 10. Why are we not taking 0 into consideration as 0 is a multiple of every number ?
@RAZSTAR kinda set me back. But 17th August To clarify just not in a good mental state to release authentic videos as my real usual self (That is the tip of the iceberg why I'm so delayed. Punished for a past life 🤣)
@@dans1129 Really sorry to hear about it man. Don't worry about this. Take care. Hope things get better for you soon. Take as much time as you need.. :) Just want to say that your videos are quite unique to what others offer. Really appreciate all the efforts till now.
Apologies for delay -- std dev as mentioned is literally how spread out is a set of numbers. 1) tells us we shrink all of them by 30% so of course the gaps between them will shrink by 30% so std dev goes from 10 to 7. Hope that makes sense in an intuitive way; mathematically you really really don't want to get into proving that but if wanted: Start: Sigma^2=sum(x^2-mean^2) where the sum is over all values in the set x. x now becomes 7/10 for each x and mean of course shrinks too to become 7/10mean So: Sigmanew^2 = sum((7/10 x)^2-(7/10mean)^2) so just take out the 7/10^2 from the sum and we get sigmanew^2 = 7/10^2sigmastart^2 (as now the sum is unchanged from what we originally had)
Reason i showed some maths there is to show it truly isn't the way to go on a lot of questions and a more intuitive view is so much better ("spread out")
Telephone question: E tells us their product doesn't sell, essentially, even if they reduce prices, so increasing production won't help sales. Does that help?
Question 35- narrowing the ownership goal. Isn’t that answer choice little vague, from the passage I can comprehend that’s it can be talking about minority group but in the answer choice it’s not explicitly stated. Can anyone help me with this?
Sorry for delay just saw - without being condescending think you may be overthinking/overemphasising the "trick" nature of the gmat. While they do try to trick you they don't do so horrifically unfairly and obviously. As such you can take their questions on good faith to a degree and understand when they ask a question it's related to how such a term was used in the passage
I really don’t understand question 21 how come 2 and 3 aren’t correct… can’t you have like one house selling at 100k and then only 130k until median and then like only 170k and it would work the total out ?
That would be a problem potentially if that was a core part of the sentence. Everything about its length follows which. One of my favourite technique for SC is cut the sentence down as much as possible: "The greatest road system built prior to X was the Incan Highway." Thats the base sentence. Then, GMAT says which refers to the noun immediately preceding it as an additional bit of non essential info basically. So separately we are told some facts about the Incan Highway You are correct I'd be concerned if they'd said 'The Incan Highway was 2500miles long and was the greatest.... Etc etc. Though even there, a highway could be extended or cut back over time so not a death rule. Though I'd be very suspicious if they didn't mention it changing length for some reason.
Hello. I know this is from the official gmat practice test, but i heard that the questions here are different than what I will find in the test. When i say different, i mean vastly dissimilar line of thought. Is that true?
Closest one can get and disagree. 770 first practice 790 real 1 week later so anecdotally hard disagree Edit: Seen that they are a decent predictor and far better than any others. R.e scores I had inadvertently been preparing for about 2 decades so didn't say that as a brag - will eventually explain in a vid Questions imo are real questions as they're from the exam board so
At this point in the question ww had already been able to rule out options not fulfilling both criteria. Since 3 violates a criteria it does not need to be checked
Yes the GMAT is weird. There are 31 quant qs and 36 verbal qs. But thrown into each section is a few questions that are 'test questions for future gmats' that do not contribute to your score. Hence you can be smashing it, expecting brutal questions near the end and bam get hit with something super easy. My first time I didn't know that and was sure that meant I'd flopped. But the score came up as 790 so, the trend of GMAT q difficulty is weird. You start off at, let's say, 650. Some early questions can therefore be quite hard. And if you are smashing it you will hit the top end of questions about 10 questions in. Then your challenge is to keep it there by not getting too many hard ones wrong and CERTAINLY not getting an easy one wrong if you got say, 3 ultra hards in a row wrong. Then randomly you'll get super easy test questions that don't count. Additionally, some 700-800 are 500-600 imo and some 600-700 are brutal. So it's all a bit of a mess. Just take it one at a time and ignore the "difficulty" of questions you get.
I'll explain this all in my first video but basically it encourages a Fuck I've spent 10 mins on last 3 questions better rush to catch up and a a result you get an easy one wrong. Which is hard to recover from, impossible near the end actually. So all in all, fuck the GMAT
The score of 800 is Quant and Verbal only. IR has a separate score from 0-8. I guessed and got I think 0/12 or 1/12 right. Hence I got a terrible IR score here. Hope that explains it
With respect (and I may retitle the video to explain!) I was sitting the exam in real time and thus not able to explain my thinking fully and as such would call this an overall exam technique video NOT a question explanation video. With that said, where were you lost and more importantly, what do you mean by I give up? If you gave up on trying to understand how every question was answered absolutely correct and not a bad idea as this isn't a good video for learning other than exam approach and perhaps the odd trick/technique and showing how I think questions should be approached in general. If you meant you give up in any other way please don't use this video being confusing as a reason to!!!
Harder than it looks with the time pressure but, yes, the quant content is not extremely advanced. However a good score does not leave much room for errors
You are so underrated! Great content. It amazes me how fast you are. I am prepping for the GMAT Focus right now, but honestly I feel like I still have a long way to go!
hope went or is going well. WISH could have uploaded more by now. will have words with universe 😉
silly focus added heaps of learning to ensure 805 fast before helping optimally. sigh ahaha. just when i crack half time 800....focus
as soon as literally can work again will be filling this channel as 1 stop shop for focus

Thank you so much for this! This channel has very big plans in future so if you're ever interested in helping out, get in touch
many thanks
thanks king
This video has been so helpful. It gave me the confidence to give mocks and after watching this video, I started doing RC without making notes which really helped me. Thanks so much, your videos are brilliant! The ease with which you solve questions is commendable.
This is really helpful! Could you please make another video in this format for GMAT focus?
Thank you!
Man you're such a machine! Thank you very much!
This is very helpful, thank you so much for uploading this.
Thank you for making this video. It really helped me understand how different my approach is and what areas I need to work on. I learnt a lot from this, so thank you!
Glad it was helpful!
Your thought process in quant to fastly translate words to maths and your ability to simplify hard questions is insane. I am taking my GMAT tomorrow and I learnt a lot from this. Hope I can score 700+ tomorrow using your strategies and patterns. Only big issue for me is I'm way too slow when it comes to CR and in the Verbal section overall, as I am unable to scan CR and RC passages. But I took a lot of notes from this video. Thank you it was very insightful!
How'd it go?
Did you pass it?
Maybe we'll never know 🥺 (dans1129 is me by the way)
He is chilling at Harvad Business School atm, too busy to think about YT@@thetutordl
Im sure mbas at harvard are chill 😉 (wouldn't know never did one nor planned to 🤣)
Though on a more serious point gmat is insanity as a test for an mba. I would NOT be a good executive. But hopefully have a confirmed gmat wr out soon lol. Utterly stupid. Why isn't it literally a mix of entrepreneur case studies, executive case studies and a public speaking recorded section (awa but spoken) with a persuasive mark. View it as an obstacle that will help your mental maths for life at least lol ((used to help writing but sc gone which while horrific was useful 🙄)
it's good to see how a 800 do the test
Why is he SO DAMN GOOD? Why!
After watching this a couple of times and understanding how well you think, i've gauged that in the 4 step hierarchy of competence, you're at the highest level, i.e. unconscious competence. The small things like how 20,000/1.25 is (20,000/5)*4 which make it so much easier to solve is beautifully simple. Brilliant stuff. Looking forward to getting more value from you.
One suggestion of a topic that I would appreciate if covered - How to practice official guide questions and practically identify and improve your weaknesses in Quant.
4 step hierarchy of competence for reference:
4] Unconscious Incompetence - Wrong Intuition
3] Conscious Incompetence - Wrong Analysis
2] Conscious Competence - Right Analysis
1] Unconscious Competence - Right Intuition
4:27 I paused there and started wondering how the heck I'm meant to calculate through this without a calculator
Thanks for making this Daniel, I just started my journey on GMAT and this was refreshing to see the way you tackled these problems.
Could you possibly elaborate more on what you wrote In the description? (Techniques for all “official” topics?)
Either way, you are a great resource. Cheers!
Book post and your wildest dreams in final stages x
Absolute legend. Thank you
Hey there! Since you mentioned to share if anyone comes across a more efficient method for solving questions, so I wanted to pass along one I found while prepping for the GMAT. In question 3 (average speed), there's a quicker way to solve it when the distance remains constant. Specifically, if someone travels the same distance at two different speeds, you can find the average speed using this formula:
Average speed = 2ab / (a + b)
Here, "a" and "b" are the two different speeds. This method is especially useful for Data Sufficiency questions and entails one important point that when the distance remains unchanged, we can find the average speed without the actual need of knowing the distance or even time for that matter.
For question 3, applying the formula would give:
Average speed = 2ab / (a + b) = 2(30)(60) / (30 + 60) = 3600 / 90 = 40 i.e., option B.
Saved. Investigating. ❤
on fire !! Cant wait for more content
Thank you! On it's way this spring! Working on it now
your verbal is so smooth, as a native speaker I imagine it helps a bunch.
It does, I won't lie. But you'd be surprised. Many native speakers get screwed over by colloquialisms and I myself found SC hardest by far. My guide, coming this year but can't be rushed I'm afraid as it is HARD to make the gmat as simple as I'm trying to, shouldn't benefit fluent or non fluent speakers
@@thetutordl bro I have to take gmat this July. So don't wait for long. Your guide would be really helpful.
This was very helpful! Could you please do a similar video for the GMAT focus as well?
working on it. I'm almost healthy and have actually started typing away. videos in future will include one ""like this"" for focus but not done in 90 mins for a students request! about 2 weeks from recovered from a nearly 2 yr illness, THEN I get to do it finally:')
The real GMAT beast
Your advice is spot on. I have been preparing for GMAT for the past month. I did get 550 on my first-ever official mock without any preparation. Then I started preparing from Manhattan Prep Materials and solving some questions on GmatClub. Then, I took the GMAT Club mock. Pretty I soon figured I was doing the problems in the old algebra way or the method I learned earlier, which is just consuming time and created panic in my mind. I soon started to find efficient techniques to replace my inefficient ones and came across your videos. It has been challenging since RUclips is filled with videos of people bragging about their "700+ scores in X months preparation strategy" Very few are actually talking about the real thing i.e. "techniques".
One question I really wanted to ask is about the "source." Apart from the Internet, do you suggest any book or website in particular where most of these techniques are given, hence cutting down the preparation time even further?
Appreciated. I'm really sorry to say, while it may exist, I didn't find it. That's what this channel will become. Should've been already. Blame some bad luck 🤣 what i can recommend though is methodically search for the broadest techniques first. By which i mean, personally, (biased) my translation method as a starter for all questions. Then methodically go through a bunch of QUESTIONS, not materials, 500-600 and 600-700, official, on gmat club (not 700-800 until crushing all prior (hint: your score is sick once thats done, screw the 700-800 with a few exceptions for the extra knowledge but 500-600 and 600-700 90% of time then 700-800 just scanning through for new knowledge not solving questions really. Just not a good way of learning.
Anyway!
So you have a basic overall question approach down for all questions via practicing because obviously a high worth skill (every question...) (*cough* translation*cough*). That solves....a lot. Then you go through these official questions seeing if you can solve them. 500-600 first. Really really should be fast, all, before moving on. Wont be at all at first. That way you identify your good methods, lacking knowledge, and lacking methods. So you search around on specific question types you're slow at or cant do (say open 30 500-600 'divisibility' questions - should cover all knowledge for that level. Manually working through topic by topic 500-600. You will find ones you cant do. Or are slow or find hard. Those you know are bloody easy. You're missing knowledge or technique. So you search until you find one reliable technique you like. And you pay attention to how easy those questions are now.
Thats a LONG process but pretty simple and efficient by definition. Why learn techniques for ones you're doing well on? Now 600-700. Immediately youll notice vastly better at these. But holes. New knowledge and method gaps. So repeat. Methodical. Long. But then you're 99% done. Don't rush this bit it's LONG.
700-800 you dont solve yet. You do the same: divisibility, OG questions only, 30 700-800. You look for new missing KNOWLEDGE not just hard questions. Will be obvious.
One example being modulus: 700-800 suddenly you have 2-3 modulus signs and all your methods break. Learn the knowledge when found.
This shouldn't take anywhere near as long as 600-700.
Now, if you want practice doing hard questions you can do some 700-800 knowing you're not missing knowledge. Otherwise you're mixing difficulty with missing knowledge and they are not the same thing. Difficulty takes years and years to meaningfully start crushing them. Knowledge takes a few weeks. Hope difference is obvious.
Truthfully if you are able to crush the 500-700s now faster than the time usually you'll have time to solve the hard ones, or some of them. But they truly don't matter like the easy ones. Very counter intuitive but just think of your score as rising up to a level and trying to survive there. All easy and medium correct, some hard right, some wrong, you've done Damn well. 760 type well on old test. Bit better on hards at cost of 1-2 easy/med? 700. Scoring dumb. People worry way too much about hard qs. Get the knowledge and that includes techniques.
That gets you easy and med correct and speed and knowledge so you have time and knowledge to solve the hard ones. Which don't matter you're now 760-790 deciding. (800 is all right, 790 I got 9 wrong once...)
I hope that makes sense and provides some structure? Very easy to search for methods on a particular question, gnat club, youtube, internet generally etc.
Thats my style of teaching for what it's worth anyway.
It's literally all your prep from 0 to fully ready outlined in, by definition, the most efficient you'll get outside of me finishing this channel or getting a damn good tutor (RARE)
Please make a Gmat Engkish video playlist similar to this
Will do. Sc is leaving the gmat in the next few months however, so won't lie, not.gonna be focusing on that
Thank you so much.
At 27:33, i think it should be 2^(n/2) * (n/2)!
Not 2^n * (n/2)!
Correct! Sorry - was in a bit of a rush 😉
Can we connect through linked in I want to leant about GMAT
@nbrahmareddy7690 afraid all focus is on building this channel atm. Watch this space in 2023. It won't be quick, I'm sorry, but I want to make full guides explaining how I got 800 in half time and so that you can do similar. Which is difficult to make but will be worth it!
@46:25 Shouldn't it be 9/x square rather than 3/x square, we ought square 3 too right?
Correct! In my defence I was doing the test so mistakes were inevitable 😉 but luckily my method for solving didn't rely on the numbers themselves
Hey! I need help understanding how you solve question 16 in quant section. I understand how you got 2^(n/2) * (n/2)! but not sure how you concluded from there that the smallest prime factor had to be greater than 50. Thanks for your help in explaining! Awesome video
Understandable - weird q: Imagine an even number: add 1. Not divisible by 2. Imagine a number divisible by 5. Add 1. Same obvious result. We know is divisible by all primes up to 50 cos literally has them as factors, so add 1 and can't be divisible by any of them. Does that help?
@@thetutordl Can you explained how you got 2^(n/2) * (n/2)!? thank you for the amazing video
I am really struggling with GMAT Prep and I don't have much time to study because round 2 application deadlines are near :(
Hope this helps
A) good luck ofc. But B) afraid I don't know you but what I can say is 2 things: 1) Almost anyone can go to 700+ with enough (sometimes many many hours prep) 2) Depending on usage and goals and reasons, think about if taking a year out to go somewhere better is worth it - wouldn't just be gmatting ofc. People always rushing everything 🙄
How did you read the first passage in 40 seconds ?!
@@dans1129 Do you recommend spending more time reading the passage in the beginning or reading more quickly to map out the tone of the passage then refer back to the passage when needed while answering questions? I ask because RC tends to eat a lot of the time i have for verbal. Thanks!
The above comment Zach was replying to which I'd rather keep separate, so have deleted my original reply on that.
Anyway, I sort of recommend a mix. Read the first question (not the options just the question) first. Then read the passage such that you understand it and can sort of remember where each bit was so you can find them quickly later. So overall I tend to recommend more thorough reading at first than less, but not ULTRA thorough; just enough to understand the passage and know what each bit was about.
Hence, me in the video is not even me following my own advice (as I should've been more thorough rather than skim reading and it could have cost me). But it was a while ago and I'm much better at the gmat now. New videos coming soon, of much, much higher quality.
Brilliant!
thank you very much
5:10 Why is it 60 and not 90?
oh wait i got it
Waiting you guys
@@chamikaposhi7362 ok
Thank you very much🎉🎉🎉
when are we expecting new videos ?
Sorry I know I keep failing to deliver- answer is genuinely soon (this month). Moving right now and essentially new videos will come as my health improves which will start rapidly having moved. Incredibly grateful for the support despite no uploads and has convinced me to really follow this and that I have something of value to share
3 years may be overkill but approve of keenness 🤣 would argue general career progression or uni focus or skill learning more important for next 2 minimum 😉 but yes leaving many many months to do 1 topic a week by doing 30min-1hr a day is how people go from 500 to 750
At risk of sounding insufferable, my prep was my degree and life of loving debates so lucked out into only needing sc prep. But that means technically I did years of prep without knowing it
(For anyone curious this led to my first 'blind what is gmat?' official mock test score being 770 which is why a course takes me so long - never mapped one out carefully for myself nor learnt best methods systematically -- course design now is via coming up with my best methods now that I choose/create then check extensively online if anyone has a better way ((they often do))
Don't want to sound like I'm making excuses - just explaining truthfully without tmi. Moving right now, finished tomorrow; this will allow my health (which has been the reason for lack of uploads) to start improving finally. With that and the fact it's part of my current 'important' and job priorities in mind, I'd be very disappointed if not this month.
Plan is for full course done by end of year - GMAT focus course easier (no SC) with new additions based on feedback and new ideas throughout 2024 and ofc tbh a full revision expected in future (2025) as I learn RUclips and new GMAT methods. If my health improves as expected this will get done. If not I don't have a choice in the matter unfortunately 🤷♂️ Hopefully people can tell l care and want to be helping and can believe me not being able to so far is just as frustrating for me as anyone else!
quantitative question 2 messed me up. Obviously if there is a higher percent in the profit than the loss, the total gain will be profit but you put that it would be a loss and got the question correct. maybe because this is british but if the dealer makes a 5000 profit from the first car and loses 4000 on the second car, how can the total be a loss?
It's a sneaky one. Translation really shines here as reading it to 'go with your gut' will steer you wrong.
1) Meant respectfully but maths in the UK is the same as Math in the US so don't worry all answers should line up!
2) The sneaky reason for loss comes out in the maths: he made 25% profit on a cheap car and lost 20% on an expensive one. Hence he lost money overall.
Also he gained 4000 on first and lost 5000 on second not vice versa
Hope this helps
You make it look so easy tbh, but I can’t do that
You can't do it yet. Nor do you need to. You need to learn how to do it but about 30% slower (I had loads of time left) and with some mistakes. You don't need 800; it is an unbelievably rare score. You need 730 for the very best courses in the world. And I have scored 770 with 6 mistakes before. I haven't scored 730 but would imagine it allows about 10 mistakes, as long as they are on hard questions. You do NOT want to get the easy questions wrong however.
Proper guides coming soon! (Within 2023)
I know it's probably too late for you and I'm sorry. But by end of 2023 everyone will see how to do this but faster and easier
@@thetutordl Hopefully sooner :D
Best way to do guides in my opinion would just be to a guide for the main topics - and try include official questions with each topic and sub-topic taught - this is the best way to reinforce the teaching.
would also help to provide 2-3 different methods to solve questions so that students can pick which seems more intuitive to them
Dear all, please read description prior to get the most out of the video!
Additionally I answer every question written so feel free to enquire :)
Also I'm sorry about any ads you get that are ridiculous I tried to minimise it without the algorithm crushing me but a new change means I've lost a lot of control on that end :(
While I of course woukd never use such tools, everyone knows adblock on Windows but fewer on android know of youtube revanced. If researching just make sure you stick to github and the main project page before downloading anything as viruses rife from fake sites. I've heard it allows youtube to continue to play when you put your phone to sleep and auto skips all adds so understand why some use it!
Iphone/mac no idea sorry :(
Finally, anyone who made it here: I assume I sound English? Is my speaking and tone clear to understand? Understand audio is the most important part about new videos and luckily have had relatively good reviews of my voice 😂 but happy to work on anything needed.
(Please take into account I truly was doing the exam so explanations etc. Won't be ideal - hopefully forgivable 😂)
Best,

Hi Sir, How to connect with you .. ?
Linkedin search Daniel Lauber gmat tutor or Gmail daniellauber6: please note I'm actually at work right now both writing a post for this channel and making my first proper videos:) additionally am still very much recovering from severe health issues last year so while I love to help people too much please do be aware any help elsewhere takes away from my limited energy at the moment to finally do this channel:) ((was so ill not even tutoring:( )
someone explain 27:14 please
Thank you so much for this amazing content. I'm preparing to take the GMAT exam in July, could you please do a personal tutoring with me? I'd really be grateful (ofcourse I know it won't be free, lol)
I truly wish I could. I've gone quiet because I'm not a complainer and it got silly but truthfully the amount of health problems and then crime from family no less the world has chucked my way is so obscene that for the first time in 6 years I can't even tutor (physically as in place to live sort out all other stuff) which since these are all random 'crappy' videos for my students is hopefully obviously something I love
Not to mention I HATE making promises and then failing; odds of this stuff I swear! Frustrated can't make these videos, tutor and on top launch my ai startup which has been 8000 hours in the making and is 200 from launch. Not whining so much as horribly frustrated
I can however, if you give me time to find somewhere to live (don't ask 🤣), give my number if you email me at daniellauber6@gmail.com and have a long chat sometime say in a week? As small as that sounds, I do believe it's likely to make your prep vastly more efficient after :)
No charge for that - despite all this I did make it quite high in the tutoring world and have made some very good investments so luckily that is one thing I don't have to worry about ((not rich lol just cash buy a 1 bed flat in London levels which is far from destitute and yes I'm proud of doing so in 5yrs of tutoring following by going on 2yrs of stolen life hopefully coming to an end! (28 now so not that ancient yet lol). All I can say is this channel is important to me for the original reason but now also for US contacts for my startup who will hopefully trust me if I make outrageous claims like "would you like $30k a year? 100pg doc, odd button click, legal or I'm off to prison for life on 10000 misdemeanors 🤣 and obviously commission but otherwise don't want a thing from you." sounds awfully suspicious I know but....8000hrs and several years and means the states will FINALLY let me in after first 2 years building in UK.
All that is to say, 100,000 subs who know I'm smart and tend to like helping people might mean a couple thousand US contacts to then ofc spread like wildfire when I make good.
Therefore this channel IS being finished and assuming no more ridiculous infernos life should return in a couple of months here.
....sorry ranted a bit at you. Frustrated would be my word; finally figured out how to use my gift to give and 2yrs of BS says no 🤣 (not a saint, chasing dopamine like everyone else and for the record fully intend to become a billionaire with my startup and if only I'd recorded the 800 in 62 mins might seem more plausible 😉 pending no more infernos. those i cannot predict. Why screw you all over with infernos on me though God? Seems mean. 🤣

Apologies just saw now will reply with number and ask you to WhatsApp me :)
Does he have other social media platforms with similar content?
No he doesn't but see new comment
Hello, How do you read and comprehend sentences so quickly ??
I will be honest and say a life of reading books when young and scientific papers probably helps. However, my overall technique for reading is to skim the 'obvious' bits and really only zoom in on the confusing harder bits for RC and CR.
Given a passage in RC I probably spend 50% of the time on 10% of the sentences as they're the worst ones.
In SC which is gone in focus (so true advice if sc is the problem is take focus!), I do similar: I literally 'cross out' irrelevant words and sections of the sentence and zoom in on things like 'between' or 'not only' or 'which' that are all trigger words.
Hope that helps a little? Overall advice if speed is issue is ask questions like this and research ways of speeding up, then practice practice practice with speed in mind but NOT speed rushing to the point of being wrong. Just try to truly get answers 100% right as fast as possible over and over with tactics like those above being practiced and you will speed up :)
Hey man, for the bicycle question. Why are both insufficient although he cycling for 18m/s is 32,400 and 6miles are 31,680?
Thanks for the video but i have maybe a dumb question about q9 - n could equal 1 which means the product would be 0, would the remainder be 0 or -24? If the latter, then shouldn’t the answer be insufficient? Thanks
no offence but why would the remainder be -24? remainders are strictly smaller in magnitude than the divider so 0 is the remainder ((not dumb q!!!))
@@thetutordl Hello - I am in the process of watching the video, and I am nowhere near your level and just starting my journey with this, but I think the point trying to be made above (linking to your point in the video about `finding the exception`) is that the exception in this case could be n = 1. This is not divisible by either 2 or 3, and gives 0, so therefore both statements aren`t sufficient as more specific information will be required on the nature on `n`?
This is me instinctively assuming that 0 isn`t a valid remainder, however.
how did you read your rc in less then a minuteeeee
give me tips for my upcoming exam plssssssssssssss
Didn't fully, just gist and frankly bad technique.
Biggest tip and please listen to this seriously: Easy wrong due to taking 10 seconds instead of 20 saves you 10 seconds at the cost of 50 points.
Very hard right because spent 5mins not 4 maybe 10 points?
Imagine your score is snakes and ladders and you want to
Finish high.
Contrary to expectations AND time taken/saved I've gotten 780 with 11 wrong and 760 with 5 wrong.
760 was 2 easy Qs silly mistakes early knocking me so far down I wasn't given hard Qs in time to recover.
Master 500-600, spend time and get 600-700 right then fuck all 700-800; you climb up snd have small snakes down for the wrong hards
Try it in a mock btw and do NOT have any quant areas you suck at. Get. The easy. Qs. Right
Then cling on with a horrible test of hard Qs from like q10 on.where you think you did shit cos had to guess LOADS of Qs
See what score you get. But google your wrong answers to see if 5-6, 6-7 or 7-8. Any easy wrong RIP score but know that's an area you lack knowledge. Go study it.

P.s. If I were to upload full guides for free better than anywhere found elsewhere (whether they be paid or free, how would you find it last annoying for me to monetise?

3) patreon etc.?
4).Affiliate links to e.g. amzon in description where I get 2% of whatever you spend?
I want to keep this free forever but if it does get popular if I can monetize it I can put in more effort. I only make such claims as I'm working on my methods to get 800 in half time (31Q.32.5V) which SURELY must generalise!

@@srilanka739 interesting. That was going to be my final option after a genuine request to share the channel to at least 5 people who will take the GMAT 1 day
For the record: my income is of course tutoring. Now a successful RUclips channel would of course allow me to increase my hourly rate due to cutting down the hours each student needs. But truthfully, as much as I love tutoring and will do a bit of it forever I'd far rather help far more people who can't afford tutoring. Hence the YT channel plan over the next 2 years. And yes, the success of that does depend on whether I'm as good as I think I am/can be; time will tell!
I don't actually teach the GMAT yet because I am not qualified to. Yes I scored 800 but that doesn't mean I can explain it to others. Hence the huge amount of time/thought put into the new course and why I can't rush it :(
(And yes, that was a subtle jab at many other so called GMAT 'tutors' who scored 760 and decided that makes them a tutor)
Why u shared ur screen @1:19:49??
I used zoom with screen sharing and recording of my screen to make the video. Not sure if you can record without screen sharing - probably can - will check thanks
you talk about students in the description ... do you have a course?
I will soon; this channel is more as a small resource to help current students that I teach at the moment, but I plan to make proper guides in future, all of which will be available here on RUclips
Great video, more and more please!
More to come!
Do you have a website where I can potentially hire you for tutoring?
By end of 2023 yes. But this site will have ALl my guides before then and only those who want an extra edge can hire me if they so wish.
How do you know all this math??? Do you practice with OG questions only?
maths at Cambridge kinda cheating ahaha. and tutor... but yes OG ONLY and almost none above 600-700 diff.

7:07 Why in question nº7, when its saying that the average of 5 different positive integers is at least 30, the 1st statement assumes that each of the integers is a multiple of 10. But what ensure that the numbers wont be like: 10,10,10,10,10. They are all multiple of 10 but the main sentence about the average being at least 30 is not ensured in this. Am I right?
Hello,
The question at 32:47 of your youtube video
if you put x=1 ( as x is positive)
in all three options
all three options do not satisfy the condition when x=1
Then the answer should be none
Will watch the video and reply properly but respectfully (and you can hear my surprise!) shows at the end no questions were wrong
Ah interesting point. You are correct if x was 1 none would be valid. But the question was if x was positive which COULD be valid? I.e. if x is some positive number that we choose which of these has a chance of working for some choices of x
Whereas the others just never work no matter what positive x we choose
That car dealers made 25% profit in first car and 20% loss in another so total profit is 5%. How was that loss??
Make 1% profit on a billion and 100% loss on a dollar and you're now a decamillionaire. Size matters 😉
Hey I just wanted to ask one doubt . In the question where you are supposed to take the mean of 5 different integers and the first statement is saying 1) every integer is a multiple of 10. Why are we not taking 0 into consideration as 0 is a multiple of every number ?
If you could specify exact question would be helpful but guessing they said positive integers?
@@thetutordl Okay that clears it. Yes its Positive integers.
@RAZSTAR tmi probably but had 2 phones, cash, a 5 grand bike (my nicest possession) all stolen from me this month
@RAZSTAR kinda set me back. But 17th August
To clarify just not in a good mental state to release authentic videos as my real usual self
(That is the tip of the iceberg why I'm so delayed. Punished for a past life 🤣)
@@dans1129 Really sorry to hear about it man. Don't worry about this. Take care. Hope things get better for you soon. Take as much time as you need.. :) Just want to say that your videos are quite unique to what others offer. Really appreciate all the efforts till now.
Can you explain question 11 ?? i didn't get it
Apologies for delay -- std dev as mentioned is literally how spread out is a set of numbers.
1) tells us we shrink all of them by 30% so of course the gaps between them will shrink by 30% so std dev goes from 10 to 7. Hope that makes sense in an intuitive way; mathematically you really really don't want to get into proving that but if wanted:
Start:
Sigma^2=sum(x^2-mean^2) where the sum is over all values in the set x.
x now becomes 7/10 for each x and mean of course shrinks too to become 7/10mean
So:
Sigmanew^2 = sum((7/10 x)^2-(7/10mean)^2) so just take out the 7/10^2 from the sum and we get sigmanew^2 = 7/10^2sigmastart^2 (as now the sum is unchanged from what we originally had)
Reason i showed some maths there is to show it truly isn't the way to go on a lot of questions and a more intuitive view is so much better ("spread out")
2) tells us absolutely nothing about how spread out they are so is utterly useless
Hi. Are you using Varsity Tutors?
No - I am an independent tutor
thank you for your videoo
You are welcome
Do we get physical pen and pad at the exam centre for calculations and notes ?
Yes.
Verbal 13th
I thought that the answer was C. I dont know why E is right because that plan doesnt even contain any price matter, isnt it?
Telephone question: E tells us their product doesn't sell, essentially, even if they reduce prices, so increasing production won't help sales. Does that help?
Question 35- narrowing the ownership goal. Isn’t that answer choice little vague, from the passage I can comprehend that’s it can be talking about minority group but in the answer choice it’s not explicitly stated. Can anyone help me with this?
Sorry for delay just saw - without being condescending think you may be overthinking/overemphasising the "trick" nature of the gmat.
While they do try to trick you they don't do so horrifically unfairly and obviously. As such you can take their questions on good faith to a degree and understand when they ask a question it's related to how such a term was used in the passage
I really don’t understand question 21 how come 2 and 3 aren’t correct… can’t you have like one house selling at 100k and then only 130k until median and then like only 170k and it would work the total out ?
Must be true not could be 😉
How does a perfect quant score get 96th percentile lol?
the incan highway question is weird
Can you say a high was 2500 miles? that implies the highway was 2500 miles and isnt 2500 miles long anymore?
That would be a problem potentially if that was a core part of the sentence. Everything about its length follows which. One of my favourite technique for SC is cut the sentence down as much as possible: "The greatest road system built prior to X was the Incan Highway." Thats the base sentence. Then, GMAT says which refers to the noun immediately preceding it as an additional bit of non essential info basically. So separately we are told some facts about the Incan Highway
You are correct I'd be concerned if they'd said 'The Incan Highway was 2500miles long and was the greatest.... Etc etc. Though even there, a highway could be extended or cut back over time so not a death rule. Though I'd be very suspicious if they didn't mention it changing length for some reason.
Hello. I know this is from the official gmat practice test, but i heard that the questions here are different than what I will find in the test. When i say different, i mean vastly dissimilar line of thought. Is that true?
Closest one can get and disagree. 770 first practice 790 real 1 week later so anecdotally hard disagree
Edit: Seen that they are a decent predictor and far better than any others. R.e scores I had inadvertently been preparing for about 2 decades so didn't say that as a brag - will eventually explain in a vid
Questions imo are real questions as they're from the exam board so
Q9 on the quant part.. I think you got it wrong. You didn’t check n=3 on A
Will check now but respectfully the overall answer was correct as shown at end
At this point in the question ww had already been able to rule out options not fulfilling both criteria. Since 3 violates a criteria it does not need to be checked
Also for the record all answers whether incorrect or not shown at end - will add to description thank you!
The RC about inflation was super easy
Yes the GMAT is weird. There are 31 quant qs and 36 verbal qs. But thrown into each section is a few questions that are 'test questions for future gmats' that do not contribute to your score. Hence you can be smashing it, expecting brutal questions near the end and bam get hit with something super easy. My first time I didn't know that and was sure that meant I'd flopped. But the score came up as 790 so, the trend of GMAT q difficulty is weird.
You start off at, let's say, 650. Some early questions can therefore be quite hard. And if you are smashing it you will hit the top end of questions about 10 questions in. Then your challenge is to keep it there by not getting too many hard ones wrong and CERTAINLY not getting an easy one wrong if you got say, 3 ultra hards in a row wrong. Then randomly you'll get super easy test questions that don't count.
Additionally, some 700-800 are 500-600 imo and some 600-700 are brutal. So it's all a bit of a mess. Just take it one at a time and ignore the "difficulty" of questions you get.
I've gotten 770 with 14 wrong that were ULTRA hard and 760 with 4 wrong before. 🤣
I'll explain this all in my first video but basically it encourages a Fuck I've spent 10 mins on last 3 questions better rush to catch up and a a result you get an easy one wrong. Which is hard to recover from, impossible near the end actually. So all in all, fuck the GMAT
8 15 , theses are the worst type of questions and take the maximum time to solve, also q 15
I have an easy way now! :)
Integrated Reasoning doesn't contribute to the score? Really? So you just guessed and got nothing wrong? I don't understand
The score of 800 is Quant and Verbal only. IR has a separate score from 0-8. I guessed and got I think 0/12 or 1/12 right. Hence I got a terrible IR score here. Hope that explains it
I lost my way here and I must say, I give up.
With respect (and I may retitle the video to explain!) I was sitting the exam in real time and thus not able to explain my thinking fully and as such would call this an overall exam technique video NOT a question explanation video.
With that said, where were you lost and more importantly, what do you mean by I give up? If you gave up on trying to understand how every question was answered absolutely correct and not a bad idea as this isn't a good video for learning other than exam approach and perhaps the odd trick/technique and showing how I think questions should be approached in general.
If you meant you give up in any other way please don't use this video being confusing as a reason to!!!
If you see this please do let me know as I would hate to think my video made anyone give up on anything in a bad way :(
Can someone explain 11?
OK seems like I don't have to worry. This is like Primary 6 math in my country 🙄
Harder than it looks with the time pressure but, yes, the quant content is not extremely advanced. However a good score does not leave much room for errors
