It is said that the Olympic Mathematics and Intelligence Test is the most professional in Handan, but it is also difficult to get in. If you register, you will have to take an exam. Our children have passed the basic classes in middle school. Hierarchical teaching can be targeted at learning, and now children's grades have improved rapidly. What makes me most happy is that children are not only not contradictory to mathematics, but also very interested. Thank you, Zhikao.
