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.

2 online midterms and online final. Lectures were directly out of the textbook (literally had it up on the projector) but there was no clear pace/was all over the place. Stopped going to lectures the last few weeks because those 8ams were BRUTAL and wasn't gaining anything. Take for an easy A, go to CLAS if you actually want to learn.

6A . Yan Z X 2 Months Ago

HW-30%, Midterms(2)-25%, Final-25%,Quizzes-10%, Attendence-10% Lectures were all over the place and & there was no clear pacing/organization. Exams were all online, attendance was not taken (points were given to everyone). Gives extensions pretty easily & is very accessible by email. Take if you want an easy A, avoid if you actually want to learn.
