wasn't attentive to student needs :(

Super disorganized, hard to understand his speech or handwriting, no response to emails, posts hundreds of hw problems but doesn't say which are important, midterms and final consists of some stuff we don't spend any time on. Didn't show up to any of his exams which all had grading errors, Yang is intelligent and a nice guy, but bad at teaching.

Extremely unorganized from the start. He writes so messily on a tablet and his explanations are so bland. He changed his grading scale so many times throughout the quarter. He never showed up to exams because they had mistakes on them. Some things on the midterms were never covered in class. Some people aren't meant to teach and he is one of them.

Pretty bad lecturer and the slides he has posted are from previous years and don't always match up with what he covered in class. There are two midterms, lowest is dropped. Lowest homework is dropped. Midterms and the final were really easy though. Easy class but poor prof IMO.

His lectures were pretty scattered and not super worth going to. He also writes out a bunch of problems and concepts but his handwriting is almost completely illegible. I had to teach myself almost all of it but the TAs had very useful resources.

He wasn't the worst that's for sure. In fact his lectures were good for the first half of the course. His lectures at the very end were kind of all over the place. His tests were pretty fair, but he constantly didn't follow the lecture slides and was unclear about certain expectations. It's a test heavy class, but doable.
