The evening self-study in Shanghai University is usually at nine o'clock. What you can do in evening self-study is as follows:

(1) Read the textbook content explained by the teacher during the day, including definitions, concepts, examples, etc. According to the teacher's explanation in class, rearrange the ideas.

2) Organize, supplement and improve your own class notes. For the short notes in class, you should supplement them according to your own classroom study on that day, so that you can review the important contents again and review them later.

3) Solve the problems left over from the course of attending lectures. It is inevitable that some content in the class is incomprehensible or some knowledge points are somewhat vague. After the above two steps, let's see if we have understood all the points that we can't understand in class. If you still don't understand, you'd better write it down in a notebook and ask the teacher or classmates after class.
