Legend for getting this out so quick! Two less modules helps with speed I guess! Agreed, good exam. I got all the same answers, so I'm happy since Flow has challenged me in the past, but I got this one! Much appreciated.
It was much much quicker doing this one! I think I like this new format. Congratulations on smashing Flow! Here’s hoping the next exam is a nice one too.

Thanks for this! i know you don’t know for certain but do you reckon exam 2 will focus on things that weren’t in the exam today as much like leslie matrices, crashing, EST and LST and amortisation and things like that?
To be honest I don’t know. One year they assessed exactly the same things on both papers. Which was crazy. There hasn’t been crashing yet. The Leslie matrix question was very easy. There wasn’t much challenge in the Finance questions. So I imagine you would be more likely to see these things in Paper 2. I also think they need to make Paper 2 a little harder.
You are more than welcome! Thanks so much for taking the time in making a comment. I really appreciate it. Reach out if there is anything more I can do to help.
You are more than welcome. The ConstructMat function seems to be one of the best kept secrets! Glad that I could help! Wishing you the very best for Monday.
I only found out about it on Thursday and urgently told my students to get it on their calculators in case they needed to use it. And by luck they did!!!
I agree with all your answers given. Really liked your explanation of Q40, I’ll be using that next year to show my students. I’d love to know where you downloaded the Hungarian algorithm CAS document, I’ll get it for next year.
really appreciate the videos man quite helpful since no one really makes videos for general, does the hungarian cas function work on the cas? or just on the software been trying to put it on my cas but no luck.
Hi! Thanks for your comment and kind words. The Hungarian Software can be downloaded by teachers and put onto your CAS using the Teacher Software. So it might be best to ask your teacher to put it on. I know there is a student software package too but don't have any experience in using it.
For Q39-40 (Network Flow), I'd be interested in seeing an attempt at Q40 with the original diagram you had for Q39. Adjusting the flow to conveniently align with Q40 depends on hindsight, which feels somewhat unrealistic (especially in an exam situation). Any thoughts on troubleshooting or alternative approaches here? Ty
Hi. Thanks for taking the time in making a comment. To be honest I don't have any other way to do Q40 other than using the information from Q39. In previous years, trying to find the maximum flow by making a serious of random cuts seemed stupid and I was forever asking if there was an algorithm. Now I know there is one, I can't think of any other way of doing it other than drawing the network 5 times, making each change and then trying to find the maximum flow. Which seems to be somewhat time consuming.
Hi :) You are more than welcome! Thanks so much for taking the time in leaving a comment. I really appreciate it. Wishing you the best of success today and Monday!

hey just wanted to ask when would the solutions for general maths paper 2 would come out! the solutions for this paper is so great that I just am sure that the solution for paper 2 would be a great help
Hi. They are transcoding now on RUclips and should be live in about 20 minutes. Well, the SD version. The HD version will take a little longer. Sorry it's taking so long. It's a BIG video file.
Hello Darren, I am aiming for a 40 study score in general maths so if you could tell me what exam scores you need to get to achieve that study score that would be helpful. Thanks
Hi! Thanks so much for your comment and question. As you might imagine, I'm asked this rather a lot ... mainly by my own students ... and I really have no idea how to answer it! It is dependent on SAC scores, the cohort you're in, the state and how well they do ... All I can suggest is just heading in there and doing the very best you can. Wishing you the very best for Friday and Monday. Please let me know if there is anything more I can do to help.
The VCE subreddit has a very helpful explanation on how study scores work and why it’s hard to give a concrete answer on what study score you’re likely to get. Also thank you Maffs Guru for the great video!
im so surprised i got those bell curve/ standard deviation questions right, i only started to understand them as i was doing the exam lol. thanks for these :)
Yo maffsguru I think there was an error in the VCAA geneal exam 2 this year in the matrix section. There were two '1's in a column for a permutation matrix. Are you able to confirm this error in your next video concerning the 2nd exam paper?
For question 40, I used the minimum cuts for maximum flows method...and adjusted accordingly with each change. I still got E, but for the change to A, I got an increase of 6 as the maximum flow would become 29 (the new minimum cut). (cutting through DE, DC, AC, GF, GH-total of 29). Is this right? You got an increase of 1. Thanks!
Hi. That's a really good question. One day, I will have a look at what you are asking and see if I can work it out. I don't really understand what you mean by "minimum cuts for maximum flow method" ... sorry. But if you got the same answer, then your method obviously works :)
Hi :) Thanks for your comment. I am all set up and ready to record! As soon as I get the paper, I'm heading home and will fire up the recording studio and start working through it :) I hope to have it live by about 10:00 pm.
Thanks for the video, exam wasn't my best but I got around what I expected. Do you have any other cool programs like the Hungarian Algorithm one that would be good for the CAS for exam 2?
For qu 23, I found it easier to sub Po and Pn+1 with a, as it's a perpetuity and these amounts stay constant. Then you get a=R x a-d Solve and R = (a+d)/a Is this method right?
The two points you choose must be on the line as you are looking to get the equation of the line from those two points. My suggestion is always choose two point which are on the line AND which cross through two points which are really easy to read from the graph. They don't have to be dots on the line. I hope this helps :)
Thanks for this great work! With qu 22 , just for the process (as the answer is correct- to add $2.47 to $2611.65) don't you need to add the interest on? If the amount was larger it might have made a difference to your answer. But because it was a tiny amount, the 3.9% interest only added altered it from 2.465 to 2.473 so they both round to 2.47. As it was, both the pre and post interest answers were the same when rounded. But the process should include adding the interest to the final payment as just adding it won't usually work. So you set n=1 and include FV as 0, I as 3.9 and find the Pmt?
I will certainly take a look. I’m fairly sure the approach I used was correct. As the 300th payment still has something left to pay and hence I need to add this to my final payment.
@@joeloakley7609 yes. I hate the way the textbooks explain it. If the loan is due to be paid out at 300 payments, then just look at the over payment or underpayment and adjust accordingly.
There are some questions that ask you to pay the final payment as a new payment...they're the ones you need to add the interest to...But not with this one!
for question 13 it said the time series is smoothed using seven median smoothing. doesn't that mean that graph is already been smoothed and we just have to read it.
That's a really hard question to be honest. I thought it was pretty easy in comparison to some of the other exams. But then I'm a teacher. You would be best placed to answer this. Some people think it was easy, others think it was hard. So, it's a matter of perspective and revision. There were some interesting "tricks" but these were really just writing questions in a different way. Wishing you the very best for Monday!
quick question if we got an answer correct that a lot of people struggled with such as the last matrixes question does that somehow make our ranking go up or does it always depend on how much we got out of 40
That really is a very nice thing to write. I can't thank you enough. Let me know if there is anything more I can do to help. And good luck with Monday!
You need to have your teacher put in on your CAS using the Teacher Software they have access to. Make sure you understand how to use it as it's not at all intuitive! Get them to download the software and install it for you before the exam tomorrow. Wishing you the very best of luck!
This is probably best done by your teacher as they have the Teacher Software which can connect to your CAS and then upload software. I don't think there is any other way.
Dang, a lecturer and teacher said that usually the first and last year exams of a particular study design are the hardest but this year's exam 1 was not that hard. What is your speculation for exam 2?
I think it was pretty easy. Some interesting new ways to ask old content. But I’m hoping the next one will be a little harder. Otherwise the grade boundaries are going to be nuts!
Hi, thank you for the solutions. But I think you might have made one mistake. For question 33, as it is an undirected graph, edges go both ways. So in that case, there should be a cycle, or multiple cycles in that graph.
I don’t really agree and all the teachers and students I have checked with agree with my answer to question 33. a cycle is basically a loop but which passes through more than one point. There is not a way to pass through the points and return to one without repeating.
Hey man, what was the place you downloaded that Hungarian algorithm function from and how do you install it on the cas, had to do it by hand today and it was rough
For question 30, how can the inverse of a matrix be the same as its inverse? I only put 2 correct for that because I could not figure out how the inverse and transpose of a matrix could be the same
It's a really small part of the Cambridge textbook. The inverse of an identity matrix is the inverse. It's one of those small things they assess on. I wasn't sure, hence I did the check using the CAS.
I went to screen 1.2 and hit MENU -> Matrix -> User defined matrix. This asked for the letter of the matrix I wanted to perform the hungarian algorithm for. I put c. The CAS showed my matrix. I then his ENTER to get the CAS to do the algorithm. I hope this answers your question.
@@MaffsGurui think my cas is different because i go on a nw slide and evrytime i go menu---> matrix, i cant find user defined matrix. all i get is the create, transpose, determinant etc
When you reverse the flow you add a new route for 10 more people. If we look at the paths which go through the new route, we see can can squeeze another 7 people through. As this was more than any other by providing more people it was the correct answer. I hope this helps.
If you learnt min cut=max flow...you make the adjustment and then it creates a new min cut of 30, which then increases the max flow to 30, which is an increase of 7 on the original 23.
Damn i thought i did well like a 40/40 but i ended up making so many mistakes where If i would to do questions the second time without knowing i got them wrong earlier, i would get it right this time
@@mrbodycatcer I'll take it, but I mainly just want a study score of around 30 for english, tryna do screenwriting, RMIT needs me to answer questions (including a 2000 word story) but I have no idea what to write about 😭
Why you always make the kind of videos that I desperately need the most :))) Just did it yesterday and base on this video and my memory i think i got around 37/40 for exam 1 :(((. Btw, your videos helped me a lot in order to achive this.
Congratulations! Thanks for taking the time in making such a great comment on my video! And for the wonderful feedback. Really glad that someone is watching the videos and finding them helpful!!! Wishing you the very best of luck on Monday :)
The best thing to do is look for the grade boundaries for recent years. They are freely available online, and see what has happened historically. Whilst this won't help with this year, it might give you some peace of mind ... or some hope.
@@ahadabdul7496 yes there is. You can find the boundaries for all subjects in 2022 here: www.vcaa.vic.edu.au/administration/research-and-statistics/performance-senior-secondary/Pages/2022-grade-dist.aspx

Just a Quick one I also answered A for Question 25 at 34:49 but I did have to eliminate all other options first due to the fact it said "the temperature was" and not "the [Maximum] temperature was" I really thought VCAA was trying to trick me but I guess not haha
Sometimes I think we can over think the questions. We’ve become so used to VCAA trying to trick us we see them where there aren’t any. Wishing you the best for Monday.
I think it was much easier than other years. They asked some regular content in a different way which was harder. But I think it was a pretty fair exam.
It’s really hard to say. I found it much easier and I think a lot of people I’ve spoken too said it was very fair and pretty easy. But then I read online that people found it hard. So I suppose it’s subjective.
@@revedoIIy good question. We haven’t had forwards and backwards scanning or crashing yet. The Leslie matrix question was pretty simple. And maybe something using matrix algebra? But these are just guesses.
Hi. You will need to get your teacher to download the program from www.ticalc.org/archives/files/fileinfo/470/47035.html and then use their teacher software to transfer it onto your CAS. I hope that helps!
Love u so much thanks but still am not sure about q16 I think because it asks for the index and I wrote 0.65 as some of questions in neap last year had weird things but anyway thanks so much I literally watch ur videos to sleep
I think you need to find something bette r to sleep to!! Unless you’re telling that I’m so boring I rock you to sleep 😀😀😀 wishing you the best of luck for Monday! Thanks so much for the kind words though!
Then let me say a massive CONGRATULATIONS! Wishing you the very best of luck for Monday. Please let me know if there is anything more I can do to help.
U might be a little off my guess is 36 (don’t take my word for it). Only because it wasn’t a hard exam, but there were questions on there that would trick some people so I don’t think it would be 37+
im so stupid i got so many easy questions wrong. minimal spanning tree question wrong is just embarrassing. from this l think got 12 wrong. actually just so dumb only started studying now.
You are not stupid at all. I had to think twice about he minimum spanning tree too! You have tomorrow to be able to smash the exam. There is still everything to fight for! Wishing you lots and lots of success tomorrow :)
Some of the questions were a little more challenging. The examiners found new and different ways to ask questions about regular content. For example the correcting for seasonality question and the perpetuity question where you needed to have some idea of algebra. I think many of the other questions were fair. Doesn’t make it any better. Fingers crossed you have a really successful day on Monday.
Exactly the same way you did for Paper 1. The chances are there will be repeated content. But as there wasn't crashing, I imagine that will be on there. The Leslie Matrix question on Paper 1 wasn't too challenging and there was no matrix algebra. So perhaps make sure you know how to do this. And consolidate anything you feel you didn't get right on Paper 1. Wishing you the very best of luck though.
@@MaffsGuru I left revision quite late for part 1 as I had to study for PE as well. But I can say your 2022 exam walkthrough helped get around an additional 5 more marks which is huge. I'm gonna do the same for part 2.
@@rexwindmill that's really good to hear! At least someone is watching my content lol. Spend the weekend binging all the rest of the videos and I hope you'll smash Paper 2 :)
I am really sorry to read this. But please don't give up. There is still Monday for you to smash it. Please let me know if there is anything more I can do. Wishing you the very best of luck.

There are some questions that ask you to pay the final payment as a new payment...they're the ones you need to add the interest to...But not with this one!
done good on this hopefully the same on monday 🤞🏻
Wishing you the very best for Monday!!
cheers beaut locking me for exam
Thanks for your comment! Wishing you the best of luck in your exams
Hi for question 36 how and what did you download to do the Hungarian algorithm?? I may need to also download it for exam 2!!
Just did a google search for Ti and Hungarian and a website popped up. Transfer to cas and then learn how to do it.
for question 13 it said the time series is smoothed using seven median smoothing. doesn't that mean that graph is already been smoothed and we just have to read it.
This was discussed on Facebook and I think the consensus was that the graph was raw data and was ready to be smoothed.
@@MaffsGuru damn, the wording got me but thanks for the solutions they are amazing.
@@krishsingh3741 very kind of you to say!
Thank you, do you think this exam is a hard exam or a easy exam?
That's a really hard question to be honest. I thought it was pretty easy in comparison to some of the other exams. But then I'm a teacher. You would be best placed to answer this. Some people think it was easy, others think it was hard. So, it's a matter of perspective and revision. There were some interesting "tricks" but these were really just writing questions in a different way. Wishing you the very best for Monday!
quick question if we got an answer correct that a lot of people struggled with such as the last matrixes question does that somehow make our ranking go up or does it always depend on how much we got out of 40
I imagine it will depend on your raw score out of 40. Not particular questions.
Absolute legend once again
That really is a very nice thing to write. I can't thank you enough. Let me know if there is anything more I can do to help. And good luck with Monday!
I'm watching the likes go up in real time and its crazy. Nice stuff Darren
I am blown away by how many people liked my video and channel. So grateful.
@@MaffsGuru I dont even do further this is just cool to see
How to I put that hunagrian calc onto my CAS?
You need to have your teacher put in on your CAS using the Teacher Software they have access to. Make sure you understand how to use it as it's not at all intuitive! Get them to download the software and install it for you before the exam tomorrow. Wishing you the very best of luck!
How do you download the Hungarian Algorithm thing onto your CAS?
This is probably best done by your teacher as they have the Teacher Software which can connect to your CAS and then upload software. I don't think there is any other way.
is there a way the hungarian algorithm solver can find the maximum total time??
Yes. But you have to change all the numbers. I'm going to do a video on this one day ... as it's a really interesting thing to know how to do.
Dang, a lecturer and teacher said that usually the first and last year exams of a particular study design are the hardest but this year's exam 1 was not that hard. What is your speculation for exam 2?
I think it was pretty easy. Some interesting new ways to ask old content. But I’m hoping the next one will be a little harder. Otherwise the grade boundaries are going to be nuts!
sweet. By the looks of it, ive got 100% on this one, thanks a lot for uploading this video mate
Well done!! You are more than welcome. Wishing you the very best of success in Paper 2 on Monday.
Hi, thank you for the solutions. But I think you might have made one mistake. For question 33, as it is an undirected graph, edges go both ways. So in that case, there should be a cycle, or multiple cycles in that graph.
I don’t really agree and all the teachers and students I have checked with agree with my answer to question 33. a cycle is basically a loop but which passes through more than one point. There is not a way to pass through the points and return to one without repeating.
Mr Guru will you upload solutions to exam 2?
Just editing them now. Will be live by 9 pm.
Thank you, really appreciate your work.@@MaffsGuru
@@MaffsGuruYayyyyy
Hey man, what was the place you downloaded that Hungarian algorithm function from and how do you install it on the cas, had to do it by hand today and it was rough
I did it by inspection
@@mrsins329yeah I did inspection too but may as well save an extra minute or two
@@mathesonavich I've got a classpad which I don't think has programs for Hungarian algorithm
I just did a search on Google and it was one of the first things which came up. Really bloody glad I found this on Thursday!!
Youi can find the software here: www.ticalc.org/archives/files/fileinfo/470/47035.html
will you upload solutions for exam 2???
he said 9pm so it shouldn't be too long now
They are with RUclips who are transcoding them now. Just 15-20 minutes longer. Sorry it's taking so long, but it's a big video file.
Thanks for being so patient. Not too long to go now.
very epic
Thank you so much! I really appreciate the time you have taken to make a comment.
For question 30, how can the inverse of a matrix be the same as its inverse? I only put 2 correct for that because I could not figure out how the inverse and transpose of a matrix could be the same
It's a really small part of the Cambridge textbook. The inverse of an identity matrix is the inverse. It's one of those small things they assess on. I wasn't sure, hence I did the check using the CAS.
I did the exact same thing turns out there’s things call orthogonal matrixs that are matrix who’s traspose and inverse are the same who knew😅
I got 90 (36/40) - do you think that’s enough for an A+?
We really won’t know until all the exams are complete. We will just have to wait and see. I’m sorry I can’t be any more help.
Thanks anyway for the video - very helpful
U should be good. Don’t stress
@@bigballer1984 thank you!
@@MaffsGuru Also will you do a video on the solutions for Exam 2 on Monday?
hey for question 36 after you wrote the matrix on the cas what did you do next???
I went to screen 1.2 and hit MENU -> Matrix -> User defined matrix. This asked for the letter of the matrix I wanted to perform the hungarian algorithm for. I put c. The CAS showed my matrix. I then his ENTER to get the CAS to do the algorithm. I hope this answers your question.
@@MaffsGurui think my cas is different because i go on a nw slide and evrytime i go menu---> matrix, i cant find user defined matrix. all i get is the create, transpose, determinant etc
@@shathasalah7605 you have to install the software from the website. I gave the link in the description of this videos. Then instructions will work.
@@MaffsGuruohhh alright got it thankss!!!
I got 39/40 :(( is it still possible to get a raw 50?
We really won’t know. But fingers crossed you get what you need. Make sure you smash paper 2 on Monday!!!
For the last question, I don't understand why is it +7 for E
When you reverse the flow you add a new route for 10 more people. If we look at the paths which go through the new route, we see can can squeeze another 7 people through. As this was more than any other by providing more people it was the correct answer. I hope this helps.
If you learnt min cut=max flow...you make the adjustment and then it creates a new min cut of 30, which then increases the max flow to 30, which is an increase of 7 on the original 23.
How do you do the hungarian algorithm on the CAS?
You need to download the software file on the internet and upload to your CAS. It is a great program to save a lot of time.
I've added a link to the software in the description
thanks so much! @@MaffsGuru
Q37 is much easier done using eulers with edges being 12 as there are 24 values in the matrix representing connections, then just use eulers formula
Agreed! But at least I've shown there is another way to do it too :)
It is easier that way but as the matrix elements add to 20 there are actually 10 edges not 12. v-e+f = 2 5-10+f=2 so f=7
Damn i thought i did well like a 40/40 but i ended up making so many mistakes where If i would to do questions the second time without knowing i got them wrong earlier, i would get it right this time
There is always Monday. So smash the paper on Monday and you can recover any loses!!!
Got roughly around 25/40, not bad not bad, my teacher says I do a lot better on short answer so hoping I do better, 2/3 days left till we do it.
solid 30 study score 🥳

question 2
What happened with question 2?
i said positively skewed with no outliers - I got it wrong@@MaffsGuru
yeah honestly same, but ig what can you do. Schools only practice for the rest of your journey. chookers!!@@arikeca5362
I got 37/40. I wanna get a 45 is it still possible? I know you can't tell but just off past years?
The best thing to do is look for the grade boundaries for recent years. They are freely available online, and see what has happened historically. Whilst this won't help with this year, it might give you some peace of mind ... or some hope.
is there a website for it@@MaffsGuru
@@ahadabdul7496 yes there is. You can find the boundaries for all subjects in 2022 here: www.vcaa.vic.edu.au/administration/research-and-statistics/performance-senior-secondary/Pages/2022-grade-dist.aspx

Just a Quick one
I also answered A for Question 25 at 34:49
but I did have to eliminate all other options first due to the fact it said "the temperature was" and not "the [Maximum] temperature was"
I really thought VCAA was trying to trick me but I guess not haha
Sometimes I think we can over think the questions. We’ve become so used to VCAA trying to trick us we see them where there aren’t any. Wishing you the best for Monday.
I have got a question. Do u this 2023 was harder or easier than 2022? Done some silly mistakes. Having 2 exams really sucks! VCAA is just ;/
I think it was much easier than other years. They asked some regular content in a different way which was harder. But I think it was a pretty fair exam.
would u say this exam was easier or harder than previous years
It’s really hard to say. I found it much easier and I think a lot of people I’ve spoken too said it was very fair and pretty easy. But then I read online that people found it hard. So I suppose it’s subjective.
@@MaffsGuru any predictions on what could be on Mondays exam?
@@revedoIIy good question. We haven’t had forwards and backwards scanning or crashing yet. The Leslie matrix question was pretty simple. And maybe something using matrix algebra? But these are just guesses.
@@MaffsGuru thanks so much!!
Woah this man speedy

how did you put the hungaran on cass?
Hi. You will need to get your teacher to download the program from www.ticalc.org/archives/files/fileinfo/470/47035.html and then use their teacher software to transfer it onto your CAS. I hope that helps!

Thanks so much! I really appreciate the comment. Wishing you the very best for your forthcoming exams!
how do we download the Hungarian algorithm software in CAS
Do a Google search for Ti and Hungarian Algorithm and you should see it come up. It’s a great little addition to the CAS.
With question 30, can't we argue that the inverse of an Identity matrix is equal to the normal identity matrix and would therefore wouldn't be true?
I’ll have a look later and come back if that’s OK. I’m pretty shattered tonight.
its still an inverse no?
@thenerdyjellyfish7150 Ahh damn. Got that one wrong then. Cheers
does general scale down by 2 or 3?
It depends on where you sit on the bell curve but generally it scales down by 2.
benchmark 23:34
Thanks for benchmarking this. Can I help with anything?
Love u so much thanks but still am not sure about q16 I think because it asks for the index and I wrote 0.65 as some of questions in neap last year had weird things but anyway thanks so much I literally watch ur videos to sleep

Congratulations! Wishing you the very best for Monday.
is 35/40 an a+
depends on the year. you won’t really know until results are released
Here here!
U might be a little off my guess is 36 (don’t take my word for it). Only because it wasn’t a hard exam, but there were questions on there that would trick some people so I don’t think it would be 37+
Is 37/38 out of 40 a A+?
We really won’t know until the exams are marked and the boundaries are set. It’s just a waiting game now.
35/40 was A+ last year
im so stupid i got so many easy questions wrong. minimal spanning tree question wrong is just embarrassing. from this l think got 12 wrong. actually just so dumb only started studying now.
You are not stupid at all. I had to think twice about he minimum spanning tree too! You have tomorrow to be able to smash the exam. There is still everything to fight for! Wishing you lots and lots of success tomorrow :)
Our school uses you as a resource!
That’s awesome!! I’m deeply grateful!!! I wish a lot more schools did!! Wishing you the very best of luck on Monday
Got 80% may as well not bother with exam 2😭
No!!! Please bother. You might find that Monday goes really well for you and not so well for others!!
Am I the only one who found some questions challenging and paper harder than past VCCA and external
Some of the questions were a little more challenging. The examiners found new and different ways to ask questions about regular content. For example the correcting for seasonality question and the perpetuity question where you needed to have some idea of algebra. I think many of the other questions were fair. Doesn’t make it any better. Fingers crossed you have a really successful day on Monday.
What do you reckon is the best way to revise for part 2?
Exactly the same way you did for Paper 1. The chances are there will be repeated content. But as there wasn't crashing, I imagine that will be on there. The Leslie Matrix question on Paper 1 wasn't too challenging and there was no matrix algebra. So perhaps make sure you know how to do this. And consolidate anything you feel you didn't get right on Paper 1. Wishing you the very best of luck though.
@@MaffsGuru I left revision quite late for part 1 as I had to study for PE as well. But I can say your 2022 exam walkthrough helped get around an additional 5 more marks which is huge. I'm gonna do the same for part 2.
