    do you think i will get the mark in the question asking you to put the dipoles on the molecule with florine if i put negative dipole on both florins whereas the paper that the alevel them guy uploaded only had the dipole on one florine? thanks also grae boundary predictions?

    I think you won't get a mark if you only put one dipole. But since you put two, that is correct.

    Yes because its essentially H2O (perm dipole-dipole).

    Looks like I'm getting a C then...based on the unofficial markscheme, I reckon I got 43. Which is so annoying because on all the past papers I did, I was getting mid to high 50's.

    What do you think the grade boundaries will be? Realistically

    it can't be higher than 52/53 for an A can it?

    52+ for an A is rediculous, that's 85%... Realistically you need to understand there where questions in this paper that could quite easily catch you out, and for a lot of people it did. Also, yes we are A2 students but we are retaking because, for the most part, we did poorly last year - there will still be a lot of students that do poorly this year too. I'm not saying they're going to be rock-bottom grade boundaries but they need to representative of all of us, and not just a student forum. I've said that imo the boundaries should be 49-50 for an A, but the boundaries should get closer together towards the B and C grades compared to usual. We'll just need to wait until results day to find out for certain, my guess is as good as yours.

    For the question about what you would see in the reaction between ZnCO3 and HCl would you get the mark if you only put fizzing and didn't mention about the solid dissolving?

    How many raw marks do you expect for 100% UMS?

    58~, 100% ums is really something we wont know until results day. Good luck if you're aiming for it!

    Having done all the past papers I can say that this type of question is quite common, and it's always 2 marks, 1 for stating there will be effervescence/fizzing and the other mark for stating that the metal/solid whatever dissolves

    Counted 55-57 marks for my answers. Hoping that's enough for 95+% UMS

    It's rarely two marks for an observationName:  IMG_20160527_151739.jpg

Size:  151.7 KB, I'm sure. Usually the second mark is for the reaction.

    I swapped the numbers to charges on the opposite ion and then balanced it out.
    it was ionic compound so you had to draw the outermost electrons of P bonded with 3 other electrons provided by Ca... 2 P atoms and 3 Ca atoms

    For the table in the first question, I got the whole table correct except for the relative mass of an electron, I stated it was negligible. Would I only get 1 mark for this or do you think they would accept negligible as an answer?
