MATH4B . Yang Xu A Month Ago

Makes almost no sense during lecture - I taught myself a majority of the material. TA's are super helpful, as they teach you patterns to recognize for exams. The exams themselves are worth 30 and 50% of your grade, so each question is either worth 1 or 2.5 percent of your overall grade. Though, the exams were pretty easy compared to the homework.

Two midterms, the lowest one is dropped. Weekly homework, the lowest one is dropped. All the exams weren't too difficult, but his handwriting during the lecture was not great.

Very easy all mcq midterms and final. lowest midterm dropped. hw due weekly online. TA resources were extremely helpful and I never went to lectures. Not the best teacher with confusing lectures so I didn't bother going.

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.
