    THe best thing about chem is that if you know the subject a 100% youare likely to get top marks.
    I love that there are no real life situations or question you have to think very hard.

    But anyway post the papers as soon as you get from the centre!!

    That's true! Some people find Chemistry hard and I don't get it. At GCSE level it's **** easy! I'm not even revising

    Hey guys, for the experiments, do we need to just learn them? Eg the oxygen experiments to show how much oxygen is in the air and the cracking experiment and the others hahha do we need to learn them?

    I don't actually know any experiments by heart, per se. If you can understand the concepts, that should be fine. However, you should make yourself aware of any catalysts listed for any reaction, because they really can't be figured out on the spot (e.g. hydrogen peroxide -> water + oxygen, catalyst is manganese (IV) oxide).

    Yesss, that's what I mean, like those experiments. Is that the evolution of oxygen? :/ I can never remember what is what. I'm generally good at chemical concepts, its just the experiments that trip me up

    Halfway done with IGCSE exams, got Chemistry on Monday morning. I used to really dislike Chemistry and got C's and D's in the class tests and mocks last year, but got 1 mark off an B in my January mock and have been improving in class.

    I would have been aiming for a B but now I'm aiming for an A. Did loads of practice papers and revision couple of weeks ago, but don't know where start studying now. Any ideas on what 'difficult topics' that require studying will come up?

    Stereochemistry of amino acids.

    Don't worry, I'm joking. To start with, make sure you know the Contact Process and Haber Process back to front, including all of the conditions, etc.
