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!

Guys I'm doing Alevel now but resitting chem 2 because my sister wanted me to and believe me, chem 2 is like a walk in the park compared with Chem 4 :frown:

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! :smile:

Well chem 2 is worth the most out of all the modules so that's a good plan :smile:

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 :smile:

Good luck with the exam :smile:

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?

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

Ahh Snap! I have a twin too :smile:

But he doesn't do the same board as me (We go to different schools)

Yeah about 23% of the exam is how science works :redface:

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

Aww you go to different schools :frown:

what's that like?

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
