Took LS4 with him. Not a great professor. His slides are pretty basic and don't convey the information needed to solve the hw problems. His answer keys for the problems contain multiple mistakes so checking my hw just made me even more confused. Not to mention the hw is practically impossible. Everyone I talked to had seemed to be just as lost as I was. Fortunately his tests are not as hard as the hw (although that is not saying much). Nothing in this class is connected. The slides are too simple, the hw is too hard, and the tests are somewhere inbetween in difficulty making it very hard to study for. If you're lucky he will put easier problems on the test; if you're unlucky he will destroy you with impossibly complicated problems
LS4: I took LS4 with this professor, and I especially liked his lecture slide. Since he was not and experienced professor, his lecture is not as smooth as other professors, but I really enjoyed the class. Exam is a bit difficult, but as long as you like calculations and probability, you should be fine.
