Professor Lee is definitely an extremely knowledgeable professor. He was constantly explaining Greek and Latin terms and illustrating connections to current law to help us understand the books more comprehensively. His method of queueing class discussion (having everyone interested in responding to a comment raise their hand and then calling on each in turn) I found to be a bit annoying, because by the time the conversation got to you, it had totally changed subject and you'd forgotten what you were going to say. However, he would respond passionately and intelligently to every point directed at him, and would always do his best to keep conversation on topic, which could be rather difficult in a class full of jackasses constantly tooting their own horns. Although he was rather inflexible with deadlines (I asked for an extension on my first paper, he gave me 24 hours and an explanation of why he wasn't going to grant one again), he did his best to be fair and reasonable, which he was.
His grading is also very fair. I received the grade I expected on all my papers within a +/-, and his comments were very direct, albeit all in a paragraph assessment (as opposed to in the margins). For a very subjective class, he certainly made an effort to objectify everything as much as possible. For the final, he provided a comprehensive study guide that had everything we needed to know on it, as well as providing multiple options for all the sections (there wasn't a single part of it where we were required to answer everything).
Bottom line: If you want to get a lot out of CC, especially on the historical and legal side of things, take his class.
