PSTAT120B . Wainwright B 4 Months Ago

Lecture not mandatory but section is with one section being dropped. The workload is super manageable but the content is difficult. It is very easy to get lost even if you go to the lectures. The average on the midterm was 40%. Your final grade is curved at the end. Wainwright is a super chill guy and will remember if you come to the lectures.

midterm was hard, but he curved a lot. Final was super essay, as far as i know a lot of people get full credits. However, his lecture was boring, but you have to go there since the explainations on the textbook were not clear. If you only read the textbook, it will be hard to get an A.

The first half of the quarter's content was covered really quickly and pretty confusing, but he slowed down a lot in the last half. Once he slowed down, I actually liked his lectures. The midterm was quite long so scores were very low, but he curved the whole class a lot at the end. The final was reasonable.

Midterm and final were difficult (especially the midterm), He accounts for it with a huge curve. Curves the entire class grade in the end Explains things clearly and throroughly answers questions Some people don't like his teaching style, but if that's the case, attendance isn't mandatory he provides a textbook that explains the material well

Professor Wainwright is a super nice guy and very helpful during office hours, but unfortunately mundane during lecture. His slides are ripped from the textbook with little elaboration, and his examples are also from the book, but often skip "trivial" steps which can make them hard to follow during lecture. Homework is graded on completion.
