1. If you want to make up, make up in the second year of high school. You should have military training first, and your class should be postponed. You should teach yourself the missing courses by self-study.

2. Credits have a great influence on you. If you don't have enough credits, you can't graduate, and of course it will affect the evaluation of scholarships and other aspects.

3. You can't make up for it through other courses, and you must take the exam again (that is, re-participate in military training).

I am a student of China Normal University, and the regulations of the school are like this.
