The GRE and GMAT are two of most used graduate exams for those seeking to study a Masters Degree or Masters in Business Administration (MBA) degree. The Graduate Record Exam and Graduate Management Admissions Test have been taken for over 50 years and are taken by approximately 600,000 and 300,000 people worldwide annually, respectively. These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.

Thank you for posting such thorough videos! Retaking the GRE 7+yrs after my last math class and I'm feeling a lot more confident with your help.
Thanks a lot man! I mean so many things happened during my at home GRE. Lots of disconnection and then my laptop shut down😞. But I still managed to score a 320. Your videos were a huge huge help!! Especially the ones where you were solving the verbal and quant sections. My approach to the questions got a lot better
Thank you for the kind comment Anisha, after you have done your exam!
@Jackie you cannot . Buy an erasable white board 4*11 from Amazon… get the odor free markers , it’s a long 4 hours to be breathing in toxic fumes and a good eraser. Also practice using it before test day . It takes getting used to
Hi Philip, these test solving sessions are really helpful and I wish you do more in the near future because these tutoring sessions are giving us so many tips and shortcuts for the test day which we usually wouldn't get by simply taking a mock test on our own. I have a test coming up in 2 weeks and I am so glad I came across your channel.
Thanks for the comment Padma. I will do more, hopefully before your test
Much love from Ghana West Africa, my exams is in a few days and with your videos ,I'm confident that I will come out with flying colors. Thanks Philip, you are the best !

Getting close to my GRE test and you make my life easier 😇 😌 🤓 thank youuuuuu
So glad to hear Melika!
30:06 love how the introduction to calculus & limits was more concise than my uni lecturer
Lol
Your explanation is very clear and quick sir. You are doing wonderful job.
You're SOOO kind! This was just the thing I was looking for! Thanks a million!
Wow thanks C
This was such a helpful video! Please do more of these. Thanks a lot for sharing your nuggets of wisdom.
Please do more of the McGraw Hill Tests. Your explanations are super useful. I'm doing the tests and using your videos to revise the questions I got wrong and improve on my overall strategy (both quant and verbal).
Will do!
Thank you so much .. your videos are really helpful .. much much better than any of the videos I see here... keep the good work
Thanks, will do!
these videos with full walkthroughs are amazing
Please do these kind of videos more often!!!!!
I went through all of the tests. For practice purpose they are good no doubt, but there are mistakes in questions plus they sometimes shuffle the verbal section's pattern to a non-standard form ( SC comes before TC etc).
Your videos are really helpful. Love from India 💖💖
Awesome! Thank you Bharath!
Your explanation are really superab. thankyou for your valuable guiding
2:28 ....if we take the x term as negative... then also we can get the answer...so the answer A is greater isn't correct....it cannot be determined...
Dude they said x is a positive integer
Great video! Will be taking my GRE on 12th Jan. and these type of videos help alot. Thanks again ;)
Good luck RS
question 8 the condition is a,b and k are greater than 0,so getting fractions aren't possible. they are positive numbers greater than zero so always A will be bigger. 3>2>1>0.
thank you so much
It's really helpful to spot my mistakes
can you explain this one to me if you don't mind?? I put answer D because when I did 0.3, 0.2, and 0.1 instead of whole numbers B was larger. I thought 0.3-0.1 are larger than 0 so that would imply. Why are fractions not possible?
Reasonably good questions
16:05 yeah that was the only question that I got "wrong." They used value y instead of usability y
Your test are very good love them nice practice video keep on doing it
Loved this. Could you please make more of these practice test videos?
Will do Nidhi :)
@@TheTestedTutor Thank you Philip ☺️
Much love i loved ur videos alot...so inspired from ur videos
This is amazing. Thank you so much, Philip! My exam is less than a month away, and my last ETS Free Practice Test I scored 320 (V: 160; Q: 160). I would like to get 335+ and was wondering whether you have a schedule/tips/suggestions on how I can improve by score? Also, how representative is the my score from practice test to the actual GRE? Thank you so so much! *Subscribed*
Thank you arielle. Real test isn't that different, just a weird environment. Obvious tip would be to watch all my GRE videos but apart from that, go over every practice test mistake to ensure you wouldn't make the same mistake twice.
@@TheTestedTutor Appreciate it!
@@ariellecatI'm taking the test next month
Can you please give some suggestions for verbal sections?????
You da man, brother!
plssss do more such videos where you take tests - i scored 17/20 :)
Please can you do a video on finding multiples in a row *Inclusive*
For question 8, although picking numbers is the way to go in a test, I find the proof intersting. For both quantities A and B, the difference between the numerator and denominator will be the same (lets call it z). Since a > b, a/b can be written as 1+ z/b, likewise quantity B can be written as 1 + z/(b+k). Now by comparing both quantities it is clear that A is bigger than B since z/b will always be bigger than z/(b+k), given that all variables are posotive.
can you explain this one to me if you don't mind?? I put answer D because when I did 0.3, 0.2, and 0.1 instead of whole numbers B was larger. I thought 0.3-0.1 are larger than 0 so that would imply. Why are fractions not possible?
@@anthonyprotopapa6278For 0.3, 0.2 and 0.1, Quantity A is still bigger than B. A = 0.3/0.2 = 1.5 while B = 0.4/0.3 = 1.33.
Let me explain it differently, since a is greater than b, we can write a as (b +z), z being the difference between a and b.
Now, Quantity A can be written as (b+z)/b or (1 + z/b).
Quantity B can be written as (b+z+k)/(b+k) or (b+k)/(b+k) + z/(b+k) which is 1 + z/(b+k).
Now compare both quantities: (1+z/b) vs (1+z/(b+k)). Remove 1 from both you are left with z/b vs z/(b+k).
Since all numbers are positive and the numerator is equal in both quantities, the value with smaller denominator will always be greater i.e. z/b > z/(b+k).
I hope it made sense 😅 although in a test you are better of plugging in numbers and examine carefully.
@@anthonyprotopapa6278even with your choices, Quantity A is greater. 0.3/0.2= 1.5
0.4/0.3= 1.33
I tried to explain further but I couldnt 😅 sorry
in section 3.. quest. no. 4 ........ circumference of the circle c/d = pi d / d = pi
so Quantity A = pi , Quantity B = pi
Answer is C (if the two quantities are equal)..
Am I right brother?
On question 7, does that still apply for a vertical line with an undefined slope and a horizontal line with slope of 0?
yes
Hi im new to your channel within minutes of seeing how well you explain the problems I know i will do really well in my GRE test. Im not ready for my test, however :(
Thanks Rebecca
For question 10, I do not think Y can be a negative integer because X & Y are multiplied to give a positive integer. It is the power to X and Y that is negative, so the solution is correct
Great Video Philip 👍
Thanks Nikita!!
Excellent as usual. :-)
Thanks for the explanation , Just started watching Regarding problem# 2 multiple of 9 ; Is 9 itself not the smallest multiple of 9 ? in that case the Numerator has to be [297-9] divided by 9 and then adding 1 which results in 33 which obviously is greater than 32 of Quant B. So answer A. Please tell me what is the flaw in my reasoning
oh sorry realized my mistake it is between 10-100 . What that "inclusive" term entails? If there were no such term as inclusive, would the math have looked different?
Hey a short question to question 7. Why is the correct answer not D? We could have a vertical line (slope infinitely big) and a horizontal line (slope 0). the product is not defined but the lines will intersect at a 90 degree angle.
dont confuse yourself. product of parallel line is 0 and perpedicular is -1.
Thx for posting this. It helped a lot.
Please do a couple verbals
Hey Phillip the question 15 compares X and Y rt , so why is zxy not considered while finding the preference for X ? X is still ahead of Y
there z is the preference not x
Thank you Sir.So kind of you
:))
For Q3, why do you need any formula, as you said, 300/9=33.33, hence there are 33 multiples of 9 b/w 1 and 300, before 10, there's only 1 multiple of 9, just subtract 1 from the max number of multiples =32. It's so much easier and conceptual if you do this. But then again, to each his own.
Shouldn't the first answer be D as x can also assume the values, -8, -9, -10... Please clarify
Would this be useful for someone taking the new version of GRE in 2024
In the product of slopes of two perpendicular lines question they didn't mention line Y is not a vertical line .So the answer should be cannot be determined
Quick Q on #6:
38:12
Why no mention of negative roots for sqrsts of 1, 3, 4?
Square root in gre must be positive...
@@TheTestedTutor Thanks! I wasn't aware of that!
Thanks for the lovely video
20:49 this question is confusing because it states that "x/y > 1"; however, it´is misleading....
Thank you for the video! Picked up more tricks from this video, thanks for showing us those secret tricks to save that little extra bit of time.
For question 7, what if the slope is 0 and undefined? Is the product still -1?
For what its worth, I had the same thought. No clue if that counts though.
For question 7 I understand that the slope x times slope of y gives you -1 due to them being reciprocals of one another. However, what about if the slope of x is horizontal and the slope of y is vertical? Is this case not considered because the vertical slope is undefined? Or is the product of them zero? Thanks
yeah i just wonder that
overthinking. perpendilcular slopes product is -1 always.
Do you work for scholarden?
I found your voice in almost every TC and SE questions!
Yes I did a few Qs for them
for #19 why choose 10 , and not another number like 20? explained
Thanks so much
Hi,
Thanks for your very helpful videos. I have a problem with the answer to quant section, question 5. You said there were 6 possibilities of z, but I think there are only 3 (8, 9, or 10). z can not be negative because the question says +8 is ≤ z (so +8 cannot be ≤ -8).
S I think the right answer is C.
Please correct me if I'm wrong.
Thanks
You are the best!
Sir, can you give the exact details of that previous video, that is, "THE QUESTION YOU SAID AT THE START OF THIS VIDEO WHERE YOU WENT WRONG", so as WE ALL MAY NOT KEEP MAKING THAT MISTAKE OVERANDOVERAGAIN.
I shall be profusely grateful for this clarification.
Sir could you please suggest me the best book for the preparation? And the latest book.
Manhattan 5lb is very good
"not too bad if you enjoy pie charts." you mean to tell me there are people out there in the world who don't enjoy pie charts
IKR
In the question 18 I double checked it but putting the number 4 then increasing it to 6. The numbers didn't add up to 4 times.
Idk Phillip, i scored 19/20 here, but not able to score in my real test, wish me luck, 3rd May it is!
Good luck for tomorrow!
Great. New subscriber
For Q7, lines x and y intersect to form a 90 degree angle, what is the slope of one line was Zero (horizontal line)? Wouldn't that then cause the product of the slopes to be Zero?
Thank you for this! Very helpful. How would you rate the difficulty of these questions?
Like 140-160 level only
Thanks for the video! Why do you do the odd numbered questions first?
That's the software not me!
Hi Philip. Great video. On question 12, when you cross multiplied why did you switch the inequality? There was no negative number. Thanks!
I was just writing the inequality the other way round, I didn't change anything mathematically. Hope that helps.
Question 13) 23×2 is 46 not 56 you made an error there, but the logic was correct it will be 18×2
Is the LAV principle mentioned particularly for cubes? Or does it work with other 3D figures? Does the figure even have to be 3D? Could you briefly explain it please?
Any similar 3D or 2D shape
The bigger value here is 10-300, shouldn't the big value be 290 instead of 300? Resultingly, divide 300 by 9 for biggest multiple.
Could you please explain question 18 more in depth :)
Would love to Noemie but would take a full video! It comes down to the length, area and volume of similar shapes always having a scale factor of x, x squared and x cubed respectively.
I'm currently pursuing my B.E in Civil (final year).. I wanna do my MS abroad on Environmental Engg.. Can you recommend a good University if possible!? (not in the US)

is quant on real GRE this easy? i don't think so
Couldn't a horizontal line have slope zero and the vertical line a slope undefined. Making the answer D?
Hi Philip, As you said at 28:00 what is similar question appears in exam and in this case if some students answer 5 and some answer -1. So in this case what will ETS do? Please do reply.
Thanks sm!
In Q 15 10:15 mins - 34 % is what percent greater than 16% - Here you simply subtracted and wrote 18% . Why not 34-16/16*100(What percent greater than formula). Like in the previous full length mock test we had a similar q(% change in profit line graph ques) 366.66% is what % greater than 21.4% . There we applied 366.66-21.4/21.4 * 100 =1600%. Why you did this one differently like subtracted directly . I am confused please explain
They are asking the number of consumers not the percentage change so it’s 34%(1000) -16%(1000) which is 180
(In case of the previous one it’s the percentage change which is greater or lesser )
Hello Sir
I want to give GMAT/GRE in feb 2021.But is confused which to give. Which exam is easier in difficulty and so that I pick easy exam and boost my score?My quants skills are greater than My verbal.
Please help.
Check out my gre vs gmat video Saksham!
do you have any resources on free practice tests online that are similar to the real one ETS gives for gre?
Kaplans free one, manhattans too
No way this is damn easy and can give false hopes before actual gre
Not damn easy, there are 12-15 questions that could come up on the real test. And even the easy ones, in the real exam you need to answer them quickly as I demonstrate here, to save time for the harder ones. Also, do check outmy recent Magoosh quant walk-through if you want a harder test.
-3 is not prime factor of 72, so -3 will not work, only 3,2 works, not -3,2
In regard to easiness/difficulty, would this be on the easier side of a real GRE?
Similar, but for the wrong question or two
23 x 2 is not 56. In minute 8:44
32:52 isn't the ans C here. Coz here it is asked, circumference is c= "pi.d" and then, c/d = pi
So both quantity are equal.. isnt this possible??
I've also thought the same but in the question it's mentioned circle c and not circumference. However even I think they meant c to be circumference most likely and hence thought of option C
I’m not really understanding, I think you’re not really explain and just working it out and expecting everyone to understand or be on the same page as you.
Explaining fully is for all my other videos
I got 16 in this test. I have a target around 165 in the main test. How far am I from my target? Can you tell me?
Not too far, maybe 158
Is the lvl of ques same in real exam?
i am half way through and have gotten every single question wrong...even the ones that seemed easy even to me i somehow screwed up...any advise/hope for me? is there anyone out there who sucks as much as i do ? or should i just give up and climb back up the church tower where i belong
Don't say that Cardi! Remember this is a Graduate test taken mostly by students from STEM backgrounds. So they may have had several year headstart on you. Everyone starts in a different place and has a different journey, yours may just take longer or may take a different route. But I do believe everyone can improve substantially.
@@TheTestedTutor thanks for encouragement Philip! I’m going to cry ... I study so hard , every little chance I get : I stay up late , wake up early, during commutes ; and I work full time . My test is in September and maybe I’m already experiencing burnout ? Anyway I’m going to keep going!!
I feel dumb 😢and my test is tomorrow. Oh gosh
Is there any negative marks in gre
Nope!
18:05
Me on every question.
Your videos are helpful, are you using ETS questions in this video?
Youre wrong for #7. Its only -1 if the perpendicular lines are non vertical. The correct answer is not enough info.
