wow, maths b? i'm sticking with the easy math option :p
ik i don't have to make any final decisions now, but was asking because i'm torn between physiology of organisms and evolution and behavior, on the off chance you did either - i don't think you know much about those though?
haha, i'm also pretty worried about chemistry! my chem is in a horrible state .-. i got away with it in hs because of the way the ib paper is structured, but i'm so bad at organic chemistry it's hilarious. nonetheless i'm probably taking it if only simply because it sounds like suicide to be a pure bio student, plus i do wanna keep my options open with regards to biochemistry/ pharmacology IB. which IB options are you taking?
