VCE Maths Methods Exam 2 - 07/11/19 - Discussion/Questions/Solutions

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.

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

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?

[Sconey]

would pi/2 - tan^-1(3) be fine?

Yep, it equals the same. Good job 

[nirgun.kaur]

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.
