I failed a course in the college exam (generally required), so I will take this course again next school year. Time takes a semester. Those who fail the make-up exam will have to wait until the next school year to study the course with their younger brothers and sisters, and then take the final exam. After passing the exam, they will end the course and get corresponding credits. Of course, I made an agreement with the teacher of this course that I would not participate in the study halfway, and the final exam would be fine. 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.
