Don't write papers after graduating from college. As we all know, graduation thesis determines whether you can graduate, so how to write a good thesis is definitely not something that can be written at once, and it needs constant practice. Four years in college, some elective courses or courses with similar situation and policies end with a paper. Because I am an engineering student, we all have to do curriculum design after the professional courses, and doing a curriculum design is very similar to graduation design, and we have to have our own designs and papers.
As for the question of repeating studies in universities, there will definitely be. Our school failed more than six subjects (whether you didn't take a new course or failed) and then directly dropped to one level. There is one in our class who has failed too many courses, almost one exam and one retest, and he will have to repeat the grade when we are promoted next semester.
The university is still very free. I heard a senior sister say that the university is reserved for leave, so I can't take it now, and I can't take it after work. That's true, but everyone can't miss class three times a semester. Classes with fewer class hours will have to be supplemented by other classes if you take more leave.
