In the online solutions PDF, for the 2015 MAT Qu2, you have written that you tried expanding (xy+y^2)^4 because that expansion includes a term which is proportional to x^3y^5. How did you know to try that term specifically, I only found it by trying to expand the bracket by squaring it, cubing it, and eventually, raising it to the power 4?

Will the 2-mark and 3-mark multiple choice questions be designed to be quicker and/or easier than the 4 mark questions? Will the 4-mark questions be a similar difficulty to past multiple choice questions and the 2/3 mark questions easier/quicker? Or is another system being used?

Q12: is it not just (3/10) * (7/9)? As in 3/10 is probability for 1st contestant to be chosen and 7/9 is probability for 2nd one not to be chosen.
