<p>I agree with Josh. I have always found that the class composition is more important than the professor or the reputation of the department -- particularly at liberal arts colleges where class discussion is a key element of the class. You don't want a bunch of "high achieving" grade mongers who have no intellectual curiosity and just want to know what is going to be on the test. </p>
<p>In retrospect, my best classes were ones where there was a mix of abilities, but where the vast majority of the students were intellectually curious and open about the subject matter. Very subjective, I realize.</p>
