SPECIALIST EXAM 2 SOLUTIONS

Sorry for the lateness...

Thoughts on the exam?

Anyone else think this has been by far the hardest specialist exam 2 by VCAA?

I don’t know, I thought it was a decently hard paper. Lots of show questions and some abstract maths. But of course there’s a tendency to overestimate the difficulty having just done it.

I though it was more difficult, but there's the factor of exam pressure etc. Also, was that the first exam 2 5 mark question ever?

Fair enough. I thought it was relatively harder as there were a lot of variables which you had to work with.

Very tough 5 marker I thought.... Also was very confused finding the area and volume for the vectors question. Rest was okay? My answers for the complex seemed a bit too basic, did anybody else just have parts of the quadratic formula for p and q?

Yeah, my p and q ended up being part of the quadratic formula as well.

I wanted to die when attempting that 5 mark mechanics question. More especially so when the assessors didn't put on AC during this exam on the only hot day this week   
(also, I'm curious as to what the volume in terms of t could be, from question 1)

I think the multiple choice this year was harder than previous years, but the short answer was pretty standard. I messed up though

momentum in the 5 marker? that was wild

Hey everyone, how did you do the first question of the vectors question? Isn't there 3 points which C could be? How do you arrive at one

A quadrilateral ABCD has C on the corner opposite A. Since AD and BC are parallel sides or a parallelogram, AD=BC

To find
in terms of t, you had to use
and
.
Also considering the terminals,
I think that should be right, checking with the normal volume in terms of y.

I thought it was clearly harder than recent years, perhaps the hardest since 2008. I think VCAA overcompensated for last year's relatively high A+ cutoff. I got the exam at 3:40 but still had about 10 marks worth to do by the time students were coming out.

Well this is worrying. I thought it was one of their easier exams while I was doing it but now I'm reading around it seems it was just so hard I didn't realise how wrong I was
