METHODS EXAM 2 SOLUTIONS
Exam 2s take a while to write up. Sorry 'bout that. We've probably made a few typos / minor errors. If you spot one, let me know, and I'll fix it maybe tomorrow.
-
Hmmm how'd u find it guys?
-
Got completely lost towards the end of q2 and q5 but other than that pretty happy with it. Had to guess 3 multi choice. Now I can only hope I didn’t do anything stupid.

What did u get for Q5 value of a for minimum area?
-
Was everyone informed about the mistake in question 5?
-
Was everyone informed about the mistake in question 5?
Yes. The axis is vertical, not horizontal
-
What did u get for Q5 value of a for minimum area?
i got a = 10^(2/3) / 10 but may be wrong
-
i got a = 10^(2/3) / 10 but may be wrong
I got that too
-
What did u get for Q5 value of a for minimum area?
I ended up with a function of a without a minimum lol I’m not the best person to ask
-
what did everyone get for the second mcq? do two identical solutions considered as two real solutions? being so dumb.
-
Anyone know how to do the 2nd last part of question 5? Also what angle did you guys get I got tan^-1(1/3)
-

yeah I literally had no idea how to find b - but yep I got that angle too!!
-

would i lose a mark if i converted the angle to degrees, but still in exact form??
-
for q3, what would happen if i wrote x= instead of t= but got the answers correct?? would that be considered as invalid??
-
If we had last answer as decimal (lol ik we werent meant to but my cas wasn't giving me exact value so with some wishful thinking I thought maybe since the wording stuffed up they originally intended for answer to be a certain number of decimal places - yes ridiculous I know)
So if you gave answer as 18.42 (something like that) would you lose the mark?
-
Also what u guys reckon the A+ grade boundary will be
Based off having done most other vcaa exams, I honestly feel like A+ could be as high as 70/80
-

I don't think so myself, maybe a bit higher than last year but I didn't feel it was that different. You could be right though.
-

Nah I think itll be like 68/80 or at max 69/80.
-
Do you guys think that a 36/40 on exam 1 and a 73/80 on exam 2 and a sac average of 91% in a decent cohort will be sufficient for a raw 40?
-

Yes, ~43+ probably
-
What was the b value?
-

I haven't seen exam 2 yet so can't speak about the difficulty and projected A+ cut offs for that but I think basically every year in the past those scores would yield a low 40 study score.
Also make sure not to double post on the AN forums as per the rules.

Yes, unfortunately.
-
What was the b value?
It was f(a) - think that gave you 9/10 or something
-on a side note, anyone else kinda happy vcaa made the mistake with horizontal/vertical cos after hearing the mistake you could guess the question was going to involve finding the area of a function by using the inverse (without even properly reading the question)
Feel like I may have missed that if they had the question right in the first place :P
-
Anyone know how to do the 2nd last part of question 5? Also what angle did you guys get I got tan^-1(1/3)
would pi/2 - tan^-1(3) be fine?
-
would pi/2 - tan^-1(3) be fine?
Yep, it equals the same. Good job :D
-
not invalid, but you would lose a mark - and it was out of one so....
-
Pretty happy with today 146-152 out of 160. But I did really bad yesterday, so looking at about 70-80% exam 1. Do I still have a chance of raw 40+ if my sacs are above average in the top select entry school (so around 85-100% GA1 depending on scaling).

Absolutely.

exam 1 32/40
exam 2 70-73/80
teacher didn't tell me the percentage but told me i am the one of the top students in a moderate cohort of around 50 people.
is there any chance of getting raw 40+ study score?
-
Alrighty. Solutions are finally up! They're on page 1 ;D

-16 last year got a 43, so yes, should easily be 40+
-

Thanks a lot! This helped me to overcome my nightmare of failing and focusing on finishing my remaining exams.
Overall, the exam was not bad. Better than exam 1 for me
-
Got 73 - 74 /80 on exam 2
38 on exam 1
Sac 1 average 45% got 85%
Sac 2 average 50% got 70%
Sac 3 average 60% got 95%
What study score should I be expecting
Thanks
-
Hmmm how'd u find it guys?
I think the paper was OK. Just a typo in Section B Question 4 f. i. should be 0.2947 and not 0.2949, other than that all answers look good to me. I'm a bit surprised that they placed a question with an infinite number of solutions with Question 3 e. Also surprised that there was a typo in the exam! You would think that there had been plenty of proof reading to avoid these mistakes.
-
Yep, it equals the same. Good job :D
I would think so since it is another form of correct answer.
-
Oh my GOD I f**king BOMBED lmao
Funny thing is that I got most of the super difficult, top of the state questions, I just messed up on suuuuuper basic crap, like calculating super simple integrals. I don't know what was happening to me, something just stopped working up there??? Maybe I was just pressing my CAS buttons wrong or something??? Either way, it stings real bad ughhhhhhhhhh.
Least I have another math subject to redeem myself with tomorrow, hopefully :-\

hiiii
do you think a raw 40 is possible with:
- SACs: top 25% of cohort
- exam 1: 36/40
- exam 2: 73-74/80
I stuffed up my first methods sac (worth 50% of SACs), so I was worried whether I could still get a 40
Also, for the transformation question where you find a,b,c,d I guessed a=-1 and b=1 would I still get a mark? haha
-
Ranked above average in a strong cohort.
GA2 - 32/40
GA3 - 60/80
What SS would I be looking at?

Yes, very possible. In fact I'd expect a 42-46. Large range as we are unsure how much this year's exam difficulty will affect scores.
Ranked above average in a strong cohort.
GA2 - 32/40
GA3 - 60/80
What SS would I be looking at?
~38-40

Consequential marking is available for methods, right? A lot of the questions would have C/S available, but I'm not sure if VCAA award them
-

Yes, I'm pretty sure that VCAA award consequential marks if a question requires the answer from a previous calculation.

What would my estimate SS be:
Sacs-74 ( top 1/3 of a cohort of 30ish students, weak-avg cohort ( last year had 1 43 ) )
Exam 1- 31-33/40
Exam 2-55-58/80

probably ~34-37 ss raw

For the area question from t=0 to T=6, I did it for the entire area by accident ( I multiplied the correct answer by 4 ). Do you reckon I’ll get consequential marks?

If you got the wrong answer with an incorrect method then you won’t get consequential marks, they’re only given if you make a small error (calculator maybe) but with the correct method/working or if the answer required values from previous questions.

Hi :)
If my SAC score is 90% in a very strong cohort (and I'm around Rank 2 or 3), and I got 37-38/40 in Exam 1 and 72-73/80 for Exam 2, what ss will I get??
-
Hey guys what kind of exam scores are needed for a 25 ss in methods
-

Probably a high D+ to low C given a below average - average sac scores.
-
Hey yall!
So i probably got a 35 or 36/40 for Exam 1, and 73/80 for Exam 2. What kind of raw study score am i looking at for Methods this year?
Edit: I'm rank 1 in a relatively weak cohort, and I averaged 94.25% on my SACs.

I got 33/40 for exam 1
68-69/80 for exam 2
Sacs 85% for all sacs
What ss would I be aiming for?
38-40 raw ss

Hey guys quick question;
For the probability question where they gave the probability rounded to 4 decimal places, I calculated the exact probability and used that for further parts of the question since they never said explicitly to use the rounded value.
Do you guys think that VCAA will accept my answer?
