Each school has its own undergraduate training plan and logs into the personal educational administration system. There are compulsory courses, elective courses and specialized courses that you need to pass. You all have to pass enough credits to qualify for graduation. There is also a deduction system. If you fail the exam, you will be recorded in the make-up exam or retest. If you reach a certain level, you will repeat the grade and drop out of school. At the same time, if you exceed the training period, you will also be expelled from school.
