Don't take him. Final and midterm weight heavy, and the tests are hard. A lots of assignments have to do. 117 is stressful and the lecture is not helpful.

Really helpful lectures, and he's good at answering questions. He didn't assign a ton of homework, but what he did assign was pretty hard so going to office hours was necessary for me. The tests were hard, but he graded and curved SUPER generously. Honestly nothing bad to say, I'd recommend him to anyone.

He only copy down the textbook on the whiteboard. test are difficult and tough grader, avoid him!!! I don't think he's aware that this is a summer course.

midterm/final average was low af. doesnt really teach and expects you to review stuff on your own. tests are difficult

To get a good grade is easy, the lectures are good, the professor is really nice, but algebraic geometry really killed me.

When there is Xiaolei, choose him. You will love him. He is not a hard grader and wants students to learn math in his class. The workload is fair, approximately 10 problems per week. The mid and final are similar to practice.

Great guy. But algebraic geometry is superrrrrrrrrrr hard

Professor Xiaolei Zhao is a great lecturer. He delivers the materials in a clear and reasonable way. His lectures are very easy to follow and they are very helpful and informative. The midterms and finals are very reasonable and there will be a curve. He also provides opportunities to get extra credits. An excellent professor.

His lectures are very clear and interesting. Some of the problems in midterm/final are kind of difficult but there will be a curve.

midterms are exactly like the practice tests and lectures are super comprehensive
