The suggestion is to start with the basic class and then consolidate it in the advanced class. 1, the basic course focuses on letting students master basic knowledge points and learn to practice basic questions.

2. The improvement class is more about educating children about different problem-solving ideas, practicing some unusual topics, and exercising children's ability to resist stress. The difference between the speed of solving problems and the thinking of solving problems requires students to firmly grasp the foundation before moving difficult points.
