you should be given some of them, best way to check is to find the formula booklet for your exam board on their website.

18 formulae .

How much harder are C3 and C4 from the AS units?

I'm thinking of doing C3 and S2 in jan so that in june I only have to do C4. Is it possible to finish S2 in 4/5 months, private study as my college only does C3 in Jan.
