Candidates in military colleges must be high school graduates under the age of 20, and candidates in public security colleges must be under the age of 22, which restricts some repeat students from applying for the exam. Most of the 8-year undergraduate, postgraduate and doctoral majors in medicine only admit fresh candidates, not repeat students. Most schools don't recruit repeat students.

Repetition, also called tutoring. Because they are not satisfied with their grades, or with their admission results, they choose to repeat and start again after failing in the college entrance examination in order to achieve a certain best state. With the release of college entrance examination scores every year, repetition will become a hot topic for some time.
