✐ Basic Concept Covers not only textbook concepts but also advanced concepts and concepts connecting to future grades, allowing students to build a strong foundation for advanced learning by solving related problems. ✐ Choisangwi [S] Through a combination of 'one sentence + image,' students can intuitively grasp the algorithm and key concepts needed to solve advanced problems. Based on this understanding, students solve similar problems to firmly build top-tier skills. ✐ Math Master Students solve a variety of advanced problems beyond the representative advanced types, including competition-level problems, to challenge themselves for the top 3%. Organized so that all representative problem types from the main content and Math Master can be reviewed one-to-one.
