    r = 2/3 a^2
    is this R = 2/(3a2 ) ?

    or R = (2/3)a2 ?

    Yep. Though technically it would be plus/minus that answer, but that's another story for a different time.

    Hi,You seem important on TSR. How long do GCSE raw marks stay on the schools system and can I ring up the exam board and ask for my raw mark?

    Also, is GCSE maths easier than a level?

    A = + sqrt of 3r/2
    A = - sqrt of 3r/2

    If you're dealing with fractions, keep it in fractions.

    Just call up your school and ask for the raw mark, they can be able to help you, rather than the exam board.
