Generally, there are eight, namely, study department, recreation department, study department, discipline inspection department, secretariat, sports department, propaganda department and organization department. As a college student, let me talk about the department I know.

The main responsibility of the organization department is to organize students to learn the knowledge of the party. Of course, joining this department can give priority to joining the party. The learning department is mainly responsible for statistics and sorting out grades, summarizing and docking with teachers. Of course, in this department, the life department must be responsible for the daily life of students. At the same time, it will also assist the dormitory management to check other illegal appliances such as high-power appliances, which is also a measure to ensure the safety of students. This is also a busy department. The responsibility of the sports department is to carry out various sports activities and organize school sports competitions, which is more suitable for some students who like sports. The Secretariat Department is responsible for the establishment and storage of departmental files and the statistics of student status files of all grades. This department is also a busy discipline inspection department, which is responsible for supervising the attendance of students. Regularly check the violation of school rules and discipline, and the discipline inspection department is also the hub of the student union. To sum up, no matter which department you join, it is an exercise for yourself. If you want to improve your ability, you must join a department or a club. It won't take up too much time, just a way to enrich your after-school life. After all, college life is not a mess, but an improvement.
