I teach math in an experimental high school. Although I haven't worked for a few years, it's not a question of enrollment. However, I still have some understanding of the fractional line. Our school is estimated to be between 575 and 580 this year. Last year, No.1 Middle School was 20 to 30 points higher than ours. This year, fewer people applied for No.1 Middle School, and their scores will definitely drop. I can only say that your score is still very promising. Good luck.
