    Grade boundaries?
    Id say:
    44 = A
    40 = B
    35 = C

    How'd it go?

    Same, but as long as you talked about van der waals' for the other molecules, you should get 3-4 marks for the question.

    THis paper was significantly harder than last years

    For full UMS last year it was 56/60. This year: I reckon 55/60

    Well, people were crying how easy it was apparently. It took me so long to do the calc question and it was an unconventional paper. Periodic trends, being the easy part of f321, didn't hold many marks either so definitely unconventional

    I thought grade boundaries will be 48/9 for an A, seemed easier than most past papers

    Potentially easier but different. People tend to revise stuff based on previous papers more, so I think a few people will skew that boundary down

    Likewise

    I did all the OCR sciences and they were all noticeably different than past papers haha I think OCR want to catch people out this year - may have worked - may not have worked; can't really tell

    Yeah it was hydrogen bonding. I put dipole dipole interactions and didn't even think about hydrogen bonds for some reason :/
