    I need to know how much I need for an A <_>

    Unit 1 - 106/120 (A)
    Unit 2 - 102/120 (A)
    Unit 3 - 48/60 (A)
    Unit 4 - 92/120 (B) - And I'm not sure my retake went any better

    Now assuming that for Unit 6 I will get around 35/60, and that 80% (480 UMS) is an A - If that's how it works, then I need 97 for this exam.

    Anyone got any clue what 97 would be?

    Worst case scenario 61/80, best case 69/80. I'm content with that

    Anyone have the chemistry unit 5 paper?

    The max A can go to is 60 for this paper, so I think 61 would be a good guess, but it all depends and your unit 4 and 6 marks could make a big difference to it.

    cz the frequency is inversely proportional to the max wavelength, and the max wavelength is inversely proportional to the temperature, so the frequency and the temperature are directly proportional!

    λT = constant

    since λ=v/f

    TV/f = constant

    TV = constant x f

    Therefore, T is directly proportional to f.

    For me worst case, 60/80 best can go upto 75, but personaly I think impossible.
    But there is hope.
