Interest: It is mainly aimed at students who have spare capacity in school, hoping to stimulate students' interest in further learning mathematics, so the scope and difficulty of knowledge are controlled.

Extension: It contains a complete knowledge system of competition mathematics, which aims to make students with outstanding mathematical ability receive systematic training, and the difficulty meets the requirements of most competitions.

Transcendence: for students who have received systematic training and have a deep understanding of competition mathematics, higher requirements and greater challenges are put forward for students, and they are encouraged to explore and think further.
