    Oh yes, I have a couple of documents that may also come in handy.

    This one's from Edexcel, thought it might help with some of the practical type questions:

    And here's a summary of all organic reactions:

    In my attempt to get all reactions onto a single A4 page, I made it a little confusing. Anyway, use it if you can decipher it!

    I really want to do well in unit 2, and I want it to be slightly less stressful in A2 so want to get a good high A in this exam...
    Good luck second time round!

    Well chem 2 is worth the most out of all the modules so that's a good plan
    I don't even need to resist, my twin did so she made me so we could "revise together" hahaha luckily my other exams aren't until mid-late June so not too much of a stress

    Good luck with the exam

    my chemistry teacher told us that this unit 2 is more just learning it off, than actually understanding it. i know there's a certain amount that has to be understood to get top marks, but do you agree that it's mostly just learning what the books say? i'm not so sure?

    Oh I thought Unit 1 2 4 and 5 were worth equal amounts for the overall grade

    Ahh Snap! I have a twin too But he doesn't do the same board as me (We go to different schools)

    That's what I thought but then I found out chem 2 is 47% of the AS level, chem 1 is 33 %

    Ahh I'm more prepared than I was for unit 1 so hoping to do better on this paper anyway so I guess it's better that unit 2 is worth more

    You get used to it lol I can't imagine what it would be like if he came to my school :curious:

    Okay thanks, most of the green chemistry is linked in with section C though right so majority of the answers are in the question?

    Btw what textbooks do you all use?

    This is off the aqa website, if you go on page 2 it tells you how much each module is worth and what they're out of
