I enjoyed Roman Civilization and it was pretty easy to me, but I like that kind of stuff. It's an upper level too!
I would NOT recommend Philosophy of the Mind. I thought it would be easy and it was just annoying. I took it as my writing exit requirement. The teacher was pretty easy on grading and word counts. The whole grade is 3 papers: 2 1500word papers and a 3000word paper, but my papers ended up being in the 800, 900 and my final paper was just barely 1500 and I got an A. But you HAVE to go to class and the teacher yells when he talks so it's just miserable to sit through. And you have to read a bunch of boring papers. Plus I disagreed with some of the things he was saying, but I didnt feel like arguing with him in front of the class at 8am.
I took Intro to Sociology, and it was good. Easy class for electives.
I took humanities and world mythology at a community college when I was in high school. Not sure if USF classes would be as easy.
My old roommates took a lit class on LOTR, but they didn't like it so much. They couldnt keep up with the readings, it was so fast-paced, and there were a lot of extra readings assigned having to do with fantasy-realism or something and it was A LOT more work than they anticipated.
Hmm... other than that I take mostly science classes. I have plenty of knowledge about biology electives.
