It is possible to make-up exams and retake elective courses for college students. Our school stipulates that the first make-up exam fails and the second make-up exam fails. If you haven't passed the graduation exam, it's hard to get a diploma. There is an exception when it is hot. I took an elective course for college students, but I can't get rid of it. After looking for a teacher, the teacher suggested that I just failed the course and couldn't get credit. . . So I think, in fact, public elective courses will definitely not affect students who get diplomas.
