To get a better feel for how your exams will be administered, I will release solutions to the sample papers QCAA have recently released. For Maths Methods, the papers can be accessed here.

Note that these solutions serve only as samples and are not endorsed by any other party.

Paper 1 (Technology-free)

Multiple choice

Questions 11-14

Questions 15-17
I should mention here that there is something I'm a bit iffy about regarding Q15. The mark allocations seem a bit off to me. The main thing is that in theory, candidate points of inflection should always be tested for concavity - this should not just be assumed, as is possibly the case in part c). Yet something "similar" to a test for concavity change appears in the next part.

Reminder that these are not endorsed by any other party, and hence not by QCAA either. It will be interesting to see what they do when they release their own solutions, assuming they will.

Questions 18-19

Paper 2 (Technology-active)
