I had one professor, who I just couldn't be bothered to wake up at 9 to hear him and his bad English showing slides of Roman ruins, so I dropped the course. I transferred into a class I liked much more.
Other than that, I've had really good college professors. I've had the WORST HS teachers, though. I had one who (fundamentalist Christian who just happened to have a son in rehab) told me that I would be corrupted if I went to Brown, that I'd join a cult and dye my hair.

She brought EVERY discussion we had, from Aristotle to Shakespeare, back to religion and how her church was the best. Another one REFUSED to give A's. Yet another one called my paper "bulls--t" and got mad when I called her out on it.

All in all, I just had an amazing amount of work designed to cause ulcers and keep us as busy as possible! I'm so glad now because I'm in college, where the teachers just aren't like that!
