Well I'm sorry if you think I'm being lazy, but I refute that. I know if may have appeared like that because I asked for a list, however that's only because after looking through the thread I wanted to know if there were any other things to revise other than those already mentioned. If that's all of what I need to revise then I'd already gathered that, so fair enough. I don't see how asking for advice on techniques for speeding my maths up is lazy, quite the contrary; I thought this would be the best place to enquire. Apologies if I appear lazy, I wouldn't want to give the wrong impression.
