I really hated my music theory III class...I know it's not a premed course, but the professor wasn't kidding when she said it was harder than Organic Chem (She took the premed courses when she went to Rochester).
I honestly had no idea what I was doing the entire time I was in there. I was completely at the mercy of my professor. Somehow I came out with a B, I think it was because she felt bad for me because I was completely clueless.
Basically it felt like I was thrown into the middle of a lake and I couldn't keep my head above water...now I just have to get through theory IV
