I rebuke this professor man!

MATH34A . Ye R 2 Months Ago

Literally so disorganized and no clear syllabus. While math is usually a strong area for me, I would sit in his lectures and not understand a single thing. DO NOT TAKE THIS CLASS unless you know how to learn on ur own

MATH117 . Ye R 5 Months Ago

To be honest I hated the guy until the final. Lectures primarily consisted of him waffling and you were better off reading the textbook. They were funny though. I got a D- on the midterm (which he curved to a C-). Then he gave an extremely easy final worth 50% of the course grade and I ended up with an A after the final curve. Peak cinema. 10/10

Horribly disorganized, bad handwriting, weird tangents, constantly corrects himself so you have to rewrite notes, and switches between going too slow and too fast. His phone went off 20 times during the final exam and he did not silence it. If you are forced to take a class with him, grading is reasonable and you do get a cheat sheet on exams.

Horrible at teaching, the tests did not reflect what he taught in class.

zero structure in lecture or section. almost no communication with students or TAs. 20+ questions of hw each week that are nothing like the exam. no information on dates/how many midterms until 1 week before. no study materials. luckily, TAs are very nice and give a lot of partial credit, which is the only reason this class was passable.
