what a few of my friends had issues with was that one with tanx/2 = t...that's 3u maths, but in 4u terms. sort of like our 2u paper question 10a - it was 2u level maths, but a 3u person who was familiar with parametrics would have done it with more ease.

but really, what's stopping them doing that? they do need to differentiate good maths students from average ones, and of course the 4u people are going to do better - they must be better at maths, do more work and learn a lot more stuff. so i'm not too fussed.
