My advice to you is to make the book "Come into Reality" that I issued when I signed up for junior high school. The topic inside is the favorite topic style of teachers outside the real world.
At the same time, you don't need to do many difficult Olympic math problems. You must let the children consolidate the foundation first, and then choose some topics suitable for the children's level to practice during the summer vacation.
In addition, the quality of the examination room is also very important. This kind of examination must not be stage fright or panic.
Believe me, there is not much difference between the experimental class and the ordinary class. Schools mainly play a propaganda role, and there is no difference in the allocation of teachers.
