What classes are there from Wujiang primary school to junior high school?

The placement test from primary school to junior high school is not based on the number of students, but on the students' grades and the placement system of our school, which is divided into parallel classes or experimental classes.

Therefore, when students take the entrance examination, even if the test numbers are next to each other, because they are divided into classes according to their grades, the students' grades are different and the rankings are in order, so the same division before and after the test numbers may not be together.
