I already stopped studying for methods. Might as well face it, I will fail the exam
... As for the rest, I think I already posted here before. 
lol....i'm the opposite. I only started studying for methods. Yes, in the last 2 months of year 12 I decided to bring back my maths skills from hybernation. Anyway hang in there!!! You're almost at your finish line, why give up? Just study as hard as you can then you know you walked into the exam doing your best.
as for me, if I stopped studying now I'll probably get in the 70's. I'm a big crammer, so most of the things I learn are right before the exam. Seeing as the exams are still in a couple of months I haven't started cramming I'll be screwed.
