A really good teacher, but almost too smart for his own good sometimes. He can be a little condescending, but the concepts are always successfully taught.

With the kinds of stuff he needs to teach, he does a good job, so you can't say he's a bad teacher.Act like a student, and he'll respect you; in terms of person and grading-wise.

He's a cool guy. I've laughed at some of his jokes before. But I really hate theorems.

He doesn't explain stuff that well and he isn't very funny or exciting and sometimes he doesn't even finish what he was saying to you before helping someone else.
