I'm a junior. I've taken biology, chemistry, and now I'm taking chem 2. Most juniors are taking physics right now, but i thought chem 2 would be better. Next year i think i'm going to take two science classes, Anatomy and Physiolgy, and Cell Biology. Should I take physic's instead of taking one of these classes.

I do not believe in maths. It is just manipulated numbers, which are not a real thing either. Numbers do not occur in nature. Can anyone convince me that maths has some basis in reality? Thanks.
