For some reason, I tend to do well under pressure. If things aren't going too well, then oddly enough I pull myself together to achieve stellar grades. But if things are going ok, then I become kind of lackadaisical.
Wierd, I know.
Ditto, I do better under pressure - particularly in exams, when you're just sat there and you HAVE to do okay. Coursework and essays are always pretty crap for me, just because I have no motivation to put my all into them.
