    In legacy mark scheme it says starch is decolourized.

    No worries I think you were thinking of biology where you test for starch


    How are you revising?

    Did you try the Jan 2013 paper and what do you think this paper will be

    I think I may have been, I did revise a lot of Biology today so I think i have it on the brain right now :P

    I generally revise using past paper questions, consolidation cards, mind maps, that kind of thing I like to try lots of things because it keeps me concentrated for a bit longer! What about you, how do you revise?

    I haven't done so yet, but I have it on Wednesday, so that will be fun! How about you, have you done the Jan 13 paper yet? I'm not sure really, the paper was apparently very difficult in January, so whether there will be a nicer paper in June, or whether it will be of equal difficulty to the Jan one, we shall see! What do you think?

    They won't ask you about the oxonium ion, because its not in the spec?
    I'm sorry for not replying to your post sooner - I must have missed it when scanning through the thread!

    Do you have the Heinemann OCR textbook? There is a bit on the oxonium ion in there - and if it's in the textbook then I assume they can ask you about it in exams. Either way, it doesn't take long to learn about and may be worth knowing

    hm provided grade boundaries are the same 32 would be a B I think, but my teacher thinks itll drop to 34 for an A rather than 36, because the papers have been made harder compared to last year. I think 38/40 was an A* for last year, but that'll drop so dw!
    Erm depends what the 32 equates to UMS wise, but you'll need 90% average over the three components so maybe 94%+ in the exams.

    Just checked 32/40 Last year was 42 UMS.


    Which leaves me with 18 UMS to drop for an A*.


    Assuming High Grade boundaries I would need like 55/60 and like 90-95/100


    It's do-able. I'm going for it. Got like 49 first time, I don't see how much harder it would be to get 5/6 more marks second time round.

    And I find Chem 5 easier than Chem 4.

    May the force be with me.

    for an A* you need 54 ums in the practical approx so you can easily make up those in the paper

    haha ikr chem 5 is so much better than chem 4, you can do it

    Cheers. Now I have realised how high I need to score time to step up the work.

    By this time next week 4/7 Chem 5 Papers will be done, and ideally above A*, and Chem 4 Legacy Question Pack will be done.

    Let's do this. I really need to finish all the papers and have them at an A* level at least by the 1st June.

    Then it shouldn't be too bad.

    Just some advice. Make sure you work so hard that you burn out too soon! I think I did that on a couple of exams last year.
