Comment:
Liu IS the worst possible math teacher. He doesn't care about actually teaching the material. There are only two tests in the entire class worth 80% of your grade, and they're on scantrons to boot! That means no partial credit and no corrected problem, he doesn't even want the work turned in. He just skims through tutorials, getting most probs wron

Comment:
David has to be the worst math professor I have ever had. He is extremely unclear. Doesn't help when asked a question. Rude. ONLY GIVES 2 TESTS! There are no practice tests, quizs, or worksheets. His tests only had about 16 questions. Unclear Notes. Expects you to know how to do the math before he explains it. Try Kate Horton or Sharon Brewin.

He was a great teacher and really wants the student to learn. His accent is sometimes hard to understand but it is obvious that he cares about the student. If he were still teaching at PCC, I would have taken him for math 95

Comment:
Well, he is VERY helpful with Math, he even let me skip Math 95 and go straight to 111B because he refreshed my memory so well, and helped me understand the matieral. At first, he was mean cause he didn't like friends talking in class, but once we got past that, he was very nice and very helpful. If you actually want to learn math, he is the teache

I disagree with you. David has awesome lectures. He makes sure the majority of the class understands before he moves on. He is very thorough and detailed. The course work is very helpful. All tests and quizes are from actual problems in the book and not just off the top of his head, like most instructors will give. YOUR TOTALLY MISTAKEN!!!!!!
