Dr. Li himself was good. His lectures were engaging and on-point. I definitely learned a lot about statistics and experimental designs from him. Li also cared about the class, and student learning. He was also considerate about logistics. Slides were released early and all lectures were recorded. Student groups with international students were allowed to pre-record presentations, too. Quizzes were open-note and 24 hours, with collaboration allowed.

Unfortunately, lectures were only a small portion of the class. Non-lecture logistics were very haphazard (although this was Li’s 1st time teaching this class and 2nd time teaching ever). 90% of the class was labs, and labs depended a lot on the TA. A couple TAs were decent, but some stunk at teaching. Furthermore, most of the class was data analysis and report writing. Reports and data analysis were long and very time consuming. Just 1 or 2 bad groupmates can ruin your experience.

Next, grading was very inconsistent between TAs. I did not know why I was graded in a certain manner for lab reports. Quizzes too were graded inconsistently. Some TAs gave differing amounts of partial credit for the same answer. Sometimes 2 students graded by the same TA got different grades for the same answers.

Tl;dr: Professor was good but class logistics sucked. Grading was frequently unclear and arbitrary, due to difference between TA's (and even amongst the same TAs).
