I once saw on the Internet that there was a school diagonally opposite the Elephant Group for one-on-one tutoring. The neighbor's children studied math in grade three there, and the effect was very good after a year's tutoring. From the original failure to more than 80 points now, go and have a look, let the teachers there analyze your child's situation and find a suitable method for systematic counseling, which not only synchronizes with the knowledge in the textbook, but also consolidates the knowledge you have learned before. After all, you'd better try to have a look these two days.
