I enjoyed Leung's teaching style/personality so much that I had to take two of his classes. He was a good sense of humor that he attempts to weave into his lectures (very amusing...but corny at times). He knew most of his student's names, which impressed me in a class of 100 or so. Definitely go to office hours and tutoring.

Leung is a great teacher, who really makes you understand what you are learning. He makes plenty of time outside of class for review sessions and general help sessions, which are wonderful. The unfortunate thing is that his tests are extremely hard. He doesn't give you any idea and usually misleads you to what they will be on, so it is hard to get an A in that class.
