What is the learning mode of Master of Mathematics in Hengge Junior High School?

Listen, it worked. In the past, I was confused in thinking and was not good at building a knowledge system framework. These problems are very difficult. Since listening to Brother Heng's class, it's very helpful to solve the problem. The teacher's lecture is very detailed, and poor students like us can understand it. We will continue to study in the future, hoping to make further progress in mathematics.
