The largest number of primary school mathematics training institutions is to cram the Olympic Mathematics. Generally speaking, the Olympic Games are held for students below grade five. Each institution charges different fees and classes are different. There are one-on-one classes, so don't worry too much about the cost. The children who come out to tutor their children have worked hard, mainly with good results. It's a waste of time to make up 30 yuan an hour. There is no 30 yuan now, not even a large class. It is suggested that parents can come to Wuhan Jianfeng Education, which is good for training.
