    They don't have grade boundaries as grade boundaries are reliant on the candidates who sat the exam (eg how well people did) and therefore as no one has done them it's difficult to set boundaries. But if you wanted a rough estimate which I like to set high it :
    80% - A
    70% - B
    60% - C

    What sort of questions do you think they'll ask about the practicals? For instance do you think they'll be a 6 marker on explaining the method or just small 2 markers?

    I'm actually getting confused about the breadth and depth practical questions so, this might be wrong but, I dunno, they might ask something about the apparatus and ask you to explain the limitations in a scenario.

    I don't think that they'll ask for the whole method in the breadth exam, although they might do that in the depth. It might just be 2-3 markers asking the reasons or what you could do to measure something.

    When you do q=mcΔT

    For ΔT do you do the highest temperature- initial temperature
    or do you do final temperature- initial temperature?

    That's great as lots of people have been asking for these. Just wondering if anyone wants me to do some model answers for both papers?

    I got 56 in the breadth paper (the public specimen one). Is that a good score? Because I have no clue I failed at the multi choice though getting 12/20 right!

    Does anyone have any really hard practice maths questions for chemistry? They're upping the ante on maths this year apparently, so I was wondering if anyone has any practice stuff that I could attempt. (Answers too, if possible.)

    Do you have the OCR chemistry textbook? There are a few challenging maths questions in there.

    56!? Woah, well, I'm not sure if that's good to others but, IMO, that's pretty good for your first exam on the new spec papers. In some schools, I've been hearing that the average is about 30-40 so, y'know your score is pretty good.

    Just revise the new spec and try the other breadth paper.

    That would be 80% so an A (depending on grade boundaries obviously). Well done!

    In the new practice depth paper (the one on the google drive link) question 5c where it asks you to identify the molecular formula of alkane X, I identified that the alkane has 7 carbon atoms in it so assumed its formula was C7H16 due to this being the general formula of alkanes. Yet the answer was C7H14, why is this?

    They might be asking for a cycloalkane. If that was the case then it would have been C7H14.
