    I thought that exam was pretty good

    What did you guys get for the section B maths questions with zinc?

    For the amount of water - X - i got 5.6

    For the question asking you to work out the mass of zinc i got something around 8 (had 16 at first)

    For the purity percentage i got 53%

    Did i get any right?

    What did everyone think of it in terms of difficulty? What sort of grade boundaries do you reckon?

    I found it okay, I didn't like the shapes, but somehow managed to get them

    I remember getting ~90% in the purity and I think I got 6/7/8 for the amount of water (x). Can't remember for the mass of Zinc I think it said give an integer value of x as well?

    Section B confused me a little (seeing as I suck at Maths) But I managed it in the end, it was an easier paper than January so I won't be expecting below a C I hope so anyways, saying that I always do stupid mistakes lol

    Oh dear, I found that was quite a difficult paper. The calculations were hard, I found the rest fairly okay.

    I got 7, 4.13g and 46% :/
    Which are wrong I know!

    i also got 7 for the water and 90.3% for the purity one..... for the mass one.... it was so hard and confusing so i literally did every formula possible coz i figured ill get at least a few marks.... i think i got something like that for one of my answers but for my final answer i got 7.something but its probably wrong!
