I went and met with this professor, and as a person he was very nice and interested in my struggles and progress as a student. However, as a teacher, the way the class was taught didn't make sense, he was hard to understand, and was self proclaimed to be falling "deeper and deeper into his senescence". Also, my TA barely spoke english.Rate My Professors ↗

This guy makes you prove a lot of theorems. He also put on the midterm i just took something that nobody knew what to do with. The secant concavity theorem. He gave a list of proofs he said might appear on the exam the week before the midterm, but this was not one of them. I had to leave the page blank.Rate My Professors ↗

hands down worst professor i've ever had. extremely unorganized, unhelpful, and does not know how to teach what he is supposed to be teaching. the board is a mess when he writes on it, and he constantly erases notes because students always find errors in his work. avoid if possible, if not, be prepared to learn yourself.Rate My Professors ↗

THIS GUY CAN'T TEACH (and he admits it too)! Must learn the material on your own...and he misses appointments. I am very lucky to have a good TA; otherwise I would have flunk this class already. If you need this material own the road, AVOID AT ALL COST....Rate My Professors ↗
