Repetition is generally because there are too many failed courses in this school year and the credits cannot meet the requirements. After repeating the grade, as long as you make up the subjects that failed the exam, the exam will pass and the credits will meet the requirements. Repetition is not only a waste of money, but also a waste of precious time, giving people a bad impression. Postgraduate entrance examination should only look at your initial test results and the assessment of the tutor interview. If you are looking for a job, your file and report card will go to the employer, and you should also have a look. Employers value your ability more than your academic performance.
