I think it is very important to choose the right cram school. First of all, it depends on the qualification, reputation, teachers and effect of the school. Then, it depends on whether the child is willing to go to bed. If the children don't want to, no matter how good the teacher is, it won't have much effect.

I heard from a friend that his daughter was poor at math. In the fourth grade, she enrolled in a small math class in Sichuan-Vietnam Training School. She attended a semester, and her grades rose from more than 70 to more than 90. You can learn about it, I hope it will help you!
