It depends on how many points you have enrolled in the elective course. If you need to take three courses, and one elective course A has 2 points, you have to apply for one more elective course B. For example, I have taken four elective courses in my university, one compulsory course is physical education class, and one can choose a variety of elective courses.

You choose the newspaper like this, but the system shows that if you don't apply, the school will think that you don't have a draft and you have to choose a new course. Some schools have regulations that you can pay points if you don't have enough credits, and some require that you complete the credits before graduation. It's best to ask a counselor for help or something, so as not to make up the points desperately in the horrible last school year.
