There are many factors in this matter, and each university is different. For example, our university has an excellent rate control. It's not easy to score above 90. Every teacher is different, some courses usually get more grades, and some teachers care more about exams. If you have a good class every day and review at last, there is no problem if you are above 85.

I usually listen carefully, but to be honest, some classes are ugly and the teacher's speech is too unattractive. Then I do my homework well. Nothing. I usually study by myself. I mainly forget to eat and sleep before the exam, so I am basically above 85. There is a saying: college study is in the first month of school, one month before the exam.

Come on! I believe you are all right.
