    Thats what i was thinking,what did you get for q13plotting the 2 graphs

    For (a) my line was parallel to the first one and a little bit above it. For (b) the line was going the opposite way for me, it had a positive slope.

    no one wouldnt be correct as i said real numbers, and both number had to be the same, so ive its something like 0<=n<=1 it can then be
    in decimal places

    I got 1<=n<=1, surely that would be correct?

    But surely,and I may be mistaken it asked for two numbers n E N,which meant you had to give a natural number,This meant that the number had to be bigger than zero and a whole number

    Nope, that would've been too easy. Question clearly said Real numbers which is what caused a lot of confusion. As long as you have two of the same numbers, I think you're fine.

    I didn't do one question. For some reason I just went blank on it. It was the one where you had to factorise x^2 - x - 6

    Anyy idea how many marks I lost on that one?

    Doubt you lost that many marks to be honest, wouldn't be too worried about it.

    The thing is I left an hour early but then realised how to do it after I left.

    I'm gonna spend the whole 2 hours for paper 2 this time.
