I think it's slightly unfair to say it was easier.

Obviously it's only because we're getting better and hence, the paper seemed easy.

If u try doing a past paper now (eg from 2007/2008), trust me, they will seem easy as well. This year's paper 2 also had 9 marks on combinations, which is unusual. But we find it "easy" but some people don't.

Paper 1, i messed up in the conversion to linear graph...i messd up on the velue of k... so obviously my next part is also gonna be wrong.... and in paper 2, i messd up on the second binomial expansion... i added instead of subtracting...and that 9 mark question i really did somethng stupid... i got -4 and -8 for the x-coordinates but for the y-coordinates i dont know what i did wrong, so also my midpoint is wrong... but got the gradient of the perpendicular as 0.5, which im hoping is right!!! stupid careless mistakes... if someone could please estimate how many marks i've lost so far out of the 160, i would be greatful!!!
