OH, & for variant 2, the combination question for choosing 7 pieces from 6 classical & 4 modern pieces..
i got 10C7 = 120ways for i) and 100 ways for ii) :) :) did anyone get the same answers?
10C7 for the first one and 100 for the third one, forgot what I got for the second one but it is fewer than 100 for sure. The answer in part ii adds up with two other possibilities to give 100.

Part i) No restriction

ii) Two pieces of modern are selected

iii) More classical pieces than modern pieces, has to contain one modern pieces.

By the way, based on the Paper 1, I've decided to some question spotting since CIE won't be stupid enough to ask the same questions twice.

So I have a hunch that functions, sets, trigo/proving and finding x, b square-4ac, coordinate geometry, graphs, integration for area under curve, differentiation, surds, relative velocity and logarithms are coming out tomorrow.

There were like two graphs Qs in Paper 1 Variant 2 :O (Three if you include the one re : y^2 = m sec x + c as well)

I dearly pray to GOD, though I'm Buddhist, that relative vel wouldn't come up. I HATE IT >:(
