    yeah I meant the last question
    i got something like that too.
    there was also a question on efficiency of a power stations, the figures were in standard form. what did you get for that one?
    i got something like 0.7% or 7%
    pretty sure i was wrong though

    0.7 is correct in pretty sure efficiency can never be above 1%

    Yeah but last year's paper was pretty easy compared to this so the grade boundaries should be pretty low.... right?




    P.S.

    Sorry for the horrible grammar
    I agree so hopefully yes

    Well I got at least half of that wrong. This was the hardest paper! Did anyone else find it difficult to finish in the hour? I spent more time reading than answering which is stupid.
    By end, I left 2 (no time) and half answered about 6!
    Horrid paper

    I really struggled with timing for this exam-it was about 12 questions.
    Does anyone else think that timing was an issue? I think OCR made this paper too long!😕
