The child is about to enter junior high school and wants to go to the middle school attached to Xigong University, but his math performance is not particularly good. I don't know where to find a good math tutorial. The middle school attached to Xigong University is not easy to enter. Generally speaking, primary school mathematics is still dominated by classes, so it is more important to practice after class, and the reason why you do less is that you do less. I think math cram schools are all like that. If the school teacher does it, you can consider signing up for one, mainly to answer questions. If many students in the society are here.
