Don't forget everyone has different standards... someone might think the paper is easy when they are expecting a lower mark for example.
I'm not sure if I said this already- but our school's Head Maths teacher said it was much more challenging & even "stupid" for a 2u paper; and that's considering he teaches 2u maths for our grade... So don't feel bad if you found it challenging- pretty much everyone from my school found it challenging too (out of those who sat the 2u paper)... and before you make any cracks at my school- unless you're in James Ruse, NSG, SG or HG, our school beat yours in 2004- and if we do it by raw number of candidates >90 overall, then only James Rusers and NSGs can talk.
And sikeveo, that was a rather inconsiderate remark by you.
