There are two ways to recruit students. One is to enroll students in advance. If your grades are good enough, you can contact the admissions teacher in charge of your area before the middle school entrance examination. There should be a small interview (I also had a small written test at that time, and I took three Olympics). If they think you are good, they will admit you in advance. At that time, the indicators given to us were the top five in county-level middle schools and the top forty in municipal middle schools.
The other is to take the senior high school entrance examination, which will refer to your ranking in your region. Scores don't seem to mean much. After all, the criteria for scoring in different regions are different. The number of students enrolled in the senior high school entrance examination is related to the past quality of students in your area. If your candidates have good high school grades in previous years, there will be more enrollment.
Our county is a small county town, recruiting 2-5 people every year.
