College students should choose courses in the educational administration system within the specified time. Generally, they only need to choose public elective courses and sophomore physical education class.

Instead of choosing courses, it is actually a class grab in a strict sense. Good classes will naturally be very popular, and there will naturally be many people robbing classes. Moreover, the capacity of the educational administration system in many schools is not very large, so it will be particularly difficult to choose courses.

Some people are stuck on the login page, and some people are stuck on the course selection page, that is, all kinds of strange scenes will appear.

Educational administrators manage class information through this module, including adding, modifying, deleting and querying class information. When adding information, open a new window to enter class information. Check whether the class number is duplicate when saving. If the added class number is duplicate, prompt the user.

Information can be added only if the information is not repeated. When deleting information, a prompt window should pop up for the user to confirm whether to delete it. Only after the user confirms it can the information be deleted. When modifying information, you should be able to modify it according to the category selected by the user, that is, list all the information of the category selected by the user and modify the category information on this basis.
