The head teacher there is quite enthusiastic. One-on-one effect is different. Although it is more expensive than tutoring, it is worth it. My son is very interested in mathematics now. Before, our children's math scores have been very poor, and changing a few tutors has not had much effect. It happens that our family lives near Dezhengyuan, so we'll go and have a look. If your children's grades are not good, you can also go there and ask them to help you find a suitable teacher.
