If you fail a course in the college exam (generally required), you will take it again in the next academic year. Re-taking the exam is called re-taking. Most colleges and universities adopt this strategy: when a student fails in many subjects in the final exam, he will be given a chance to make up the exam in the first week of next semester. If students pass the failed subjects in the make-up exam, they don't need to retake the exam, but if more than a certain number of subjects fail, they must retake these courses.

Or four years later, there are still subjects that have not passed, and they need to retake the exam before graduation and pass the exam before graduation. Maintenance needs to pay a certain repair fee. Reconstruction can be divided into two types: shifting classes and opening special teams.

Many college students are afraid to tell their families the disgraceful fact that the decoration fee is "failed". However, the amount of decoration fees is generally relatively large, which has caused a certain economic burden to college students without fixed income. This phenomenon has attracted media attention. Although the Ministry of Education has clearly pointed out that colleges and universities around the country are not allowed to introduce new charging standards, and some colleges and universities have stopped charging revision fees, there is no systematic revision review system in colleges and universities across the country, and many schools still "go their own way" in revision fees.
