Reviews of professor Weilin Li

Rating: 4.0/5, difficulty: 3.0/5
His lectures are clear and organized. Homeworks test the important concepts and are returned back on time. Exams are fair. Would definitely take again.

Rating: 1.0/5, difficulty: 4.0/5
70% homework, 30% final Only focuses on very specific analysis concepts and completely skips the algebra. Lectures are sterile white powerpoints dense with text and symbols. Claims his unforgiving and inconsistent grading is because he is "preparing you to become a researcher" but actually it's just plain hazing. Rude in office hours.

Professor Li is very caring that he is always willing to help you, and his lecture is informative. Although there are weekly quizzes and HW, these are important to build up a solid foundation. He is not a tough grader, so you will be fine as long as you complete these assignments by yourself.

Professor Lis class is very lecture heavy. He gives out weekly homework and quizzes as well. However, he is very caring in class. He tried his best to answer every question we raised during the lecture. He made it easy for us to understand some difficult concepts in maths. His grading is not hard for the midterms and final. I would take him again.

Good professors. Posting notes after class, notes are clear. Also clear in lecture. HWs are weekly and can be done in few hours. Exams are much easier than expected. Moreover, he is the fastest prof I have ever met, no matter in terms of HW grading speed, exam grading speed, albert grade release speed.

Professor Li is very nice and caring. He gives out clear lectures and posts written notes after every lecture. Weekly homework is useful for revising. Quizzes and exams are easier than homework. Very patient during office hours. Would definitely take him again.

This class is pretty lecture-heavy, but Prof Li conducts the materials pretty clear, and his class notes and recordings are all available, which are fairly helpful. No unpredictable or unreasonable tests. And the relatively heavy workload is a tradeoff- missing one assignment/ quiz or even screw up one test won't influence a lot.

Very difficult class if you are not good at calculus. I dropped my economics major because of this course. Weekly quizzes, lots of homework, very tough midterms with minimal curve. I ended up pass failing, it was that tough for me, but if you are mathematically inclined you will probably be fine but get ready to work.

This class is made up of 70% homework and 30% final exam. The lecture consists of tons of slides. Final exam is extremely hard, and it is not very related to what we learned in class. Although we have three days for the final exam, many of the questions are still too hard to solve completely. Besides, the grading for the final is harsh and strict.
