Straight up just copied out of a textbook. He did not explain proofs well enough that made sense. i'd avoid him. grades on a curve cuz the tests make no sense. or maybe im just stupid...

Smart and handsome guy. Really into math stuff. But the grading is a bit harsh but luckily he curves the grades finally..

Don't take him. Final and midterm weight heavy, and the tests are hard. A lots of assignments have to do. 117 is stressful and the lecture is not helpful.

Really helpful lectures, and he's good at answering questions. He didn't assign a ton of homework, but what he did assign was pretty hard so going to office hours was necessary for me. The tests were hard, but he graded and curved SUPER generously. Honestly nothing bad to say, I'd recommend him to anyone.
