There are many key mathematics in junior high school exams, because any school wants to select some flexible students to improve its long-term learning rate. As for the quality of these schools, I personally think that the fifth middle school is relatively loose and will give children some space to play freely; No.9 middle school is strict, and the management comparison board; The seventh middle school is somewhere in between. If you have strong self-management ability, it is better to attend the fifth middle school, and the education method in the fifth middle school is more suitable for the connection with the first middle school; If you are lazy, go to No.9 Middle School. Children with poor self-control will be better controlled because they hold on tight. Therefore, there are more senior children, but the stamina is insufficient. In fact, where there are good children, the key is to study hard and exercise yourself. It's the same everywhere, especially in junior high school.
