It's normal for universities to have evening self-study. Under normal circumstances, freshman schools will uniformly require self-study at night. After freshman year, you can choose whether to attend evening self-study according to your own situation. Of course, many people still don't want to attend. You can arrange your own time. Before entering the university, after three years of intense study life and time arrangement in senior high school, the university time is relatively more, and many students hope to have more free study time in the university. In particular, you can get rid of self-study at night and finally be free to arrange "nightlife". However, many colleges and universities still require freshmen to follow the evening self-study system until their sophomore year.
