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

    for example this is aqa's

    Re: C4
    18 formulae :eek:.

    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.

    I don't get why you said it was not in the booklet and I don't get what the 'face' means. Am I going crazy ?

    The face means that I am embarrassed by my error
