Winter 2021 - Make sure you understand materials on time because lecture pace is fast. Don't procrastinate. He expects you to not only apply proved theorems in class and homeworks, but also understand the ideas behind those proofs. Watch out as these ideas will appear in exam question. Exams are tough. He gives practice exams. I suggest you work through these practice exams, as you will have a great advantage on the actual exams. If you have concerns/questions, it's better to ask him during OHs instead of emailing/piazza. It may feel a little intimidating, but he's willing to explain a concept until you get it. He is a very kind soul.

Winter 2019 - Juana Sanchez is a really good professor, you just have to be polite and make her feel that you are involved in the class. Her exams are pretty long but the questions are not that hard. She provides very clear and concise study notes and the homework are helpful for the midterms and final. Some people complain that she gives them anxiety but don't take her too seriously, she is not mean, she just wants everyone to study the minimum required. She is actually pretty helpful in office hours, so don't hesitate to go and see her to ask questions about the class or homework. The material of the class is very interesting and really not that difficult overall.

This was Professor Xu's first time teaching 100B and he closely followed the textbook, so the lectures were pretty dry in my opinion. There was also no random sign-in sheet that was passed around. Homework problems were mostly taken from Professor Christou's homeworks. The exams were straightforward, but they were not open book/notes. We did not get to use a calculator until the final. He had two grading schemes: Straight scaling and curving. For curving he would give top 25% A, next 25% B, and so forth. For the curving grading scheme, he said he would fail people if they did really bad in the class, e.g. 40 on final. Although I have never been to his office hours, I have heard he is extremely helpful during them.
