I am a sophomore in Nanjing University of Posts and Telecommunications. Because of various reasons, the credit is not good, and I want to repeat my studies, and I am not a student of Tongda University. What are the specific consequences? Please tell me. All your failing classes are equivalent to being retaken. If many people fail that course, the school will offer another make-up course. If there is no class, take a freshman class. Pay attention to online course selection, which will be explained later. Ask the counselor if you don't understand. In fact, you can try not to score as much as possible, and just make up the poor credits. Grading depends on your consciousness. After all, there won't be too many people grading the whole class. Grading has little effect on graduation. Anyway, as long as you get all the credits and have enough grade points, you can graduate. The only difference is that you spent an extra year.
