Reviews of professor Sidong Lei

Rating: 2.0/5, difficulty: 3.0/5
Likes to spend time on the proofs for the calculus behind every concept, which is not very relevant when it comes to quizzes and tests. The online homework is assigned through MasteringPhysics and I feel like I learned more from the homework than I did in lecture. He takes attendance at random. Easy grader, easy to talk to.

Professor Lei is the real deal. He knows the material extremely well and I believe he does a good job of putting this material into lectures. If you show up to lecture and complete the Mastering Physics homework, you will be fine.

Great professor, always accessible. Pushes students to go above and beyond in learning physics, but if your not about that, no problem. His priority is getting you the grade you want and there are many extra credit opportunities. His unique exam and grading style will leave you stress free all semester long.

Never showed up to class, only his TA. Does not reply to my emails. No contents are posted in iCollege. Given assignments with no instructions.

I took Dr. Lei for Physics 2211K and have him for 2212K. He is extremely knowledgeable of physics concepts and does a good job showing us the concepts. He is very reasonable when it comes to quizzes and tests. If you do the Mastering Physics homework you will get extra practice to help you on tests. He also allows an extra credit presentation.

He is a great professor take him for physics he gave us two take home tests and optional final but he will also teach you physics if you're trying to learn it he gives a lot of options to fix your grade.

Dr. Lei is a good person and passionate about Physics but does not know how to teach it to new students. I WOULD NOT want to take his class as my first physics class out of High School. He has little to no structure in his teachings and jumps between topics with no clarification. He assumes you know the things he does as a Ph.D. Couldn't recommend.
