My children come from Wang Gang Middle School, where they study in a small class of 2-4 students. The effect is very good and the price is very affordable. The most important thing is that the teachers there are very responsible. My child went in August, and the first four classes were one-on-one for my child, because I didn't find a student with the same foundation as my child. After school started, I found a student with the same foundation as my children and joined them. I am very satisfied with the teachers there.
