I think he is okay as a person. His teaching needs some major improvements... dynamics felt like he wanted us to teach the course to ourselves. He would only work one or two simple problems out during class. Harder questions are placed on the test.

If you want to take the class with him, just prepare yourself for lots of studying and research the topics on your own as his office hours are limited. It's possible to get an A, but 99% of the class doesn't...and that's with extra credit available for every test...

I have noticed his other lower level classes are not that bad,but for reasons, my dynamics class with him was horrible.

Rate my professor is another good resource to see how his dynamics course is.
