I'm planning to go in to medical field, so I'm thinking a science major right? Right now im in year 3 highschool. Math isn't my greatest but I must say I'm decent but in science(I've only take chem 11) I think I'm above average. Now year 4 is quite near (after this summer) and these are my courses; English, Chem 12, Physics 12, Bio 12, Advanced Functions (math), Calculus and vectors *adv. function pre. req.*, Philosophy, and Active living (gym.) Is the course work too much? In one sem. the easier I can have is English, Philosophy, Math 12, and Gym. Next semester I will pretty much die; Physics, Calculus, Biology, Chemistry! And for one thing I don't know anything about Calculus!! Bio and Chem are required, Physics is recommended. In short: What the heck is calculus? Is this too much for one to handle? Tips on time management? And in the future what am I looking at before becoming an MD.
