1. Freshmen, the school has a unified arrangement for course selection. So don't worry too much. Don't worry. It doesn't matter what class you choose. What matters is choosing the right teacher. You will understand this sentence later ... from the heart.
If you are an old student, if you choose a bad course, I can understand the pain. My practical experience is that it is the wisest to take Yang Dong's class. I don't call the roll once a semester and hand in my papers in groups at the end of the semester. I won't go into details about other categories. I'll send you a picture about the comments of some common public teachers in foreign universities.
I hope I can help you ~ ~
