There are evening self-study classes in universities. Generally, freshmen in universities only study by themselves in the evening, and the study in universities is mainly self-study, that is, a way of learning by using their spare time to independently choose teaching materials and counseling materials and arrange study plans. In addition to regular classes at school, students also arrange some time for concentrated self-study and homework, which is called "self-study". For example, reading early before class is called self-study early, and self-study can be arranged in the afternoon after lunch and in the evening. Students learn by themselves completely during their study hours, and teachers can also help in class. Self-taught examination is the main way of university study, that is, to choose teaching materials and counseling materials and arrange study plans independently in spare time. The college self-study exam is different from the high school and junior high school self-study exam. In junior high school, it is generally supervised by teachers, but in college, everyone is consciously learning and learning to enrich themselves.
