I took Calderon in Fall '08 and he's probably the worst professor I've had at UCLA so far. Basically, he's really flaky-he took a good 3 weeks to grade our midterms and it's the 2nd week of Winter quarter now and I have yet to receive my grade for Fall. It's been almost 5 weeks since we took the final. He just didn't bother to turn it in. He told us we could e-mail him questions about our term papers and then he didn't bother to respond to them. Besides the grading fiasco, he just doesn't seem to care too much about teaching. Our lectures almost always ended about an hour early, which of course I don't really mind, but it just shows his lack of enthusiasm and dedication. Also, he has an air of arrogance about him. He constantly name-drops and talks about the prestigious universities he's attended and taught at and is pretty rude and condescending to his students. Obviously, I didn't have a great experience in his class and I definitely would not recommend him.
