So, it seemed like a good start for me, pre-med/bio, and I signed up for my bio class -- I found out, as Professor Drennen did, that I had to take chemistry as well. I wasn't as upset, I was sort of a neutral chemistry person at this point, but I thought it was pretty smart to get it over with on the first semester, so that's what I did.
