i found the exam significantly more challenging than previous years, as had nearly everyone in my fairly large cohort

Personally, Im happy the last question was tough, allowing me to focus on other parts. Hopefully 5 for q 15 and 80 raw

Btw, e4 cut off predictions? Taking into account it was 74 for the 2014 hsc, i would say mid 60s

Yeah you probably have a much better idea of the consensus then, with a larger cohort.

Probably in the 80's, mid 80's I'd guess.

Does anyone have a copy of the exam paper?

No idea why that ellipse textbook question was there. Probably easiest 4 marks of the entire test.

One reason they ask Q's like that I think is because they want to try and ensure that everyone gets at least some marks.

If you find P'(x) you'll be able to get a discriminant from that. Not sure after that.

And 14aii

Interesting that they chucked a combinatorics problem in Q16 when they did that last year (to be fair, the problems were quite different though).
From a quick glance it seems like the paper only started to get interesting at around q15

7 is (D)

$\bg_white \noindent The result is that x^{2} - y^{2} =k and xy = \frac{1}{2}k (k > 0) are 45^\circ rotations of each other.$
