I ABSOLULTELY LOVED CC BECAUSE I TOOK IT WITH LEE!!! I thought that he did a great job of encouraging discussion, and he asked great questions that provoked thought. He explained the books excellently, and I really took a lot away from the class. I'm surprised that people were bored in CC with Lee; I thought he made the texts as interesting as possible. He never really lectured, but he would lead the discussion in such a way that students could come to conclusions themselves (but he would make it clear what the right answers were so you are set for midterm/final purposes). I never thought that I would be interested in CC, but I really think that Lee made the books relevant and fascinating, making CC my favorite class that I have taken at Columbia so far. Lee is also really approachable if you have any questions or concerns. He's definitely an easy grader, and the midterms and finals are easy to do well on, too. You don't have to do the reading to do well in the class either (I tried to read as many of the books as I could but at Columbia time is always limited as we all know...so I ended up skipping a couple completely and reading select sections from others), but reading the books definitely makes your experince in the class better.
If you take good notes in class, you will be set to write papers for Lee and do well on his midterms and finals.
Also, he will meet with you about your paper topic ahead of time, and he accepts outlines of papers ahead of time too, which allows you to basically have your paper approved before you start. I would say most people in the class ended up with B+ or A-'s for not too much work, and you could get an A by putting more time into your papers/speaking in the discussion in class. I had a much better experience with CC than any of my friends, too.
DEFINITELY take CC with Lee!!!
