Meaningful. Every school has its own educational administration system, which is the busiest at the end of each year and the beginning of the school year, because our final grade and course selection system are gradually opened during this period. Usually, there is a class hour behind our academic performance, and different subjects have different classes. The more class hours, the more important this subject is.

Many people say that class time is to restrict students and force them to study, but it is not. The class schedule is a constraint on teachers. Teaching pays attention to step by step. If there are no class hours, some teachers have no plans to give lectures. I believe it is possible to complete four months in two months, but the effect is unknown.

In addition, for some students who don't want to attend certain classes and don't like certain classes, I personally think that we humans are only qualified to comment if we do the annoying things well. Therefore, existence must be reasonable. It is absolutely meaningful for universities to stipulate class hours, not only for teachers, but also for students.

The role of the credits:

Credits are a reflection of your study at school, which means that you have completed enough courses required by universities. Some schools still need innovative credits before they can graduate. European and American universities have a credit system. As long as you take enough credits, you can graduate, no matter how much time you study. As long as you study normally, everyone's credits are the same, and the rest depends on your grades.

Credit is a unit of measurement used to calculate students' learning volume. Calculated by semester, the specific academic achievements of each course and practice link shall be subject to the provisions of the professional teaching plan.
