    Can someone either link me to an existing post with written answers, or type up their answers to the written ones so we can debate? I'll add it to the mark scheme in the first post after.

    I'll also attempt to remember my answers...

    Do you think AQA will get rid of the mark for the graph intercept or will they only compensate those who used 300,000 ohms?

    Why are you using the 30nC and not the 60nC charge? I know most people got an answer around 4.5 x 1^(k) (dont remember the power) but i got the double of that answer.

    I used 60nC/4pie0 (5-2) rather than 30nC/4pie (5-2)

    Then times it by the 60nC charge to find work done.
    Doesn't matter where you use each charge as you get the same answer 😊

    In the past exam boards have just given everyone either full marks or no marks at all as it won't have an effect on the grade boundaries anyway

    i acutally think we should, I thought that if it was 300 ohms it would be halved however 300k was too small so for some reason I made it bigger instead as such a small value made it seem odd (which of course is completey wrong)

    For 3B, I said the capacitor will not fully discharge, so not all the energy stored will be used, will this get a mark??
