I'm absolutely amazed how someone can say so much yet explain so little. Hes smart af but the lectures are all over the place. If you want a solid foundation in this class then prepare to self study.

Although he is an intelligent man he is almost neglectful of students. He did not post reviews for any of the 3 tests and stopped having class a week early for review for the final but provided no materials. He then changed the grading criteria after the final on a whim. class wasn't difficult but he sure is.

EXTREMELY easy prof. No exam whatsoever. 1 HW per week, with HW answer literally at the end of textbook used in class. I took this class as a fun GE (as a physics major) knowing that he wouldn't add too much to my course load, but if you're a math major that need a rigorous hyperbolic geometry foundation, he is probably not your best choice.

Excellent professor! The lecture is clear and the grading is easy.

Take all your classes with Zetian he is SO easy!

He is kind and a very easy grader. Take the class for an easy elective.
