Ha! Zacken should do this one; I posted an equivalent formulation in his STEP thread just a few days ago!

This (Q4) is a lot easier - there seems to be a lot of variation in the standard of the questions.
8. I was trying to have a varied range of topics so they haven't always been the most difficult questions in the exam. They're still reasonably interesting though.

I think that the average UK A level candidate would replace the word "interesting" with "terrifying". The Aussie standard for people at that age seems exceptional.
10. Well these are from the Maths Extension 2 exam, taken by top candidates, so I guess kinda like STEP(?)

Right, that makes more sense. I thought someone earlier had said that this was standard Aus A level standard.
12. Perhaps top end of A-Level FM, you could say. But even their standard Maths exam (equivalent to A-Level) includes stuff that ours doesn't, e.g. rigorous Euclidean geometry, tan(theta/2) identities, product-to-sum formulae, internal and external division of a line in a given ratio, proof by induction, limits (including sinx/x), differentiation from first principles, properties of the parabola as a conic, curve sketching, small-angle approximations (sinx~x etc.), equations of motion, simple harmonic motion, simple combinatorics, probability (so Australian students are required to study mechanics and statistics), derivatives of inverse trig functions, etc.
