Art History.
I took Art History 203. It was surprisingly more interesting than I thought it was going to be. I actually took it at night at St. Mary's University College in the south part of town. The great thing about taking it there is, the prof (Bershad) teaches the exact same course at the U of C but to an auditorium of 400+ people. Where as at St. Mary's it's only about 25 students, and he brings in donuts! It also might be cheaper and closer to where you live. You will appreciate everything to do with art and architecture of the time so much more. Plus Bershad makes it really interesting and has lots of fascinating stories.
