Rating: 5.0/5, difficulty: 2.0/5
Very good teacher. Patient and be willing to solve problems all the time.

Professor Li did not really teach all semester as much as he stood there and spoke AT us. His grading criteria were unclear and inconsistent (for example, grading a 30 point question as a zero because of an initial error - every math teacher follows your error through)! He is difficult to get in touch with and even worse at communicating.

Best math professor! With clear lecture, beautiful notes, and reasonable homeworks. Super patient, friendly, and helpful during office hours.

Rating: 5.0/5, difficulty: 2.0/5
Professor Li's lectures are always logical and clear. As long as you pay attention to the lectures, you won't have difficulties in the exams and homework. Somebody might say the mid-terms are too hard or tough graded, but this is math's problem, not the professor's problem.

Everything analytic in a course called linear ALGEBRA. Everything algebraic is quite easy and he would give the proof, while everything complicated and analytic will be left as homework. 3 days finals, all about analysis; some of them are not related to the material he gave. Don't expect anything algebraically from Weilin-Analysis-Li.
