I still think its not fair that there are two variants for every paper, and with much different difficulties. Comparing (MJ10) Paper 41 (A threshold 66) and Paper 42 (threshold 54), 42 is suicide. During the exam this difficulty can effect the rest of the 'easy' questions as well due to frustration and the inability to solve the 'harder' questions. God help us tomorrow, and I hope it'll be an easy paper(s), as my preparation is a disaster, despite countless hours of study, this paper is a walk in hell.

To be honest, I'm finding it MUCH harder, but maybe it's due to the fact that I'm self studying, maybe if there was a good A2 teacher here, I would have found it easier.
I scored a B in chemistry, the worst of my AS grades, and hence I must do really really well if I will have to raise it to an A, but I hardly see that coming, in fact I'm praying for a B right now.

Lol, I know! I think this exam is the least exam I have prepared for, in like, well since starting the IGCSE's. That's not the problem, it's that I HAVE prepared, ALOT! But suddenly now everything Chemistry related text I read, It's like pure gibberish.

I'm not sure, it is the 'OH' that is responsible for the peak, so..
I think it's the same, but you never know with CIE, so I think its better to be safe than sorry.
Gd luck.
