Generally speaking, the course fees for each grade are different. Some are calculated according to class hours. My child has just entered the first grade and is now applying for mathematics. At first, he listened carefully to a small class of about 8 people. Because of the poor foundation of primary school, junior high school math scores have dropped a lot. It seems that 1 classes are all tens of dollars, which is not very expensive. If you want to go there, I suggest you go first.
