    Boundaries for this? I thought it might be really high but after the little places to catch out people I'd say 49-50 for an A.

    I made a complete guess of OH- but i know it's wrong. I think it is ClO-, that would make more sense. I agree it was a weird paper, nothing like other past papers. I think i'm looking at 53/54 out of 60 which should be an A? What do you think grade boundaries will be?
