I know how you feel! I feel like someone sold my email address to every college in the united states. It's insane! My plan is just to apply practically everywhere, then choose based on where I get accepted.
Well then, let me tell you all about it! At my school, my degree is composed mainly of general chem 1&2, organic chem 1&2, bio 1&2, biochemistry, statistics, calculus, and physics 1&2, which can be substituted for anatomy and physiology if a student chooses to do so. Oh, plus the labs for all of those lol! It's definitely not easy, but if you like it, it's worth it. Last semester I decided that I wanted to be a mass communications major and switched to that. My grades shot up.... But I was bored, so now I'm back to this!
