① After summarizing the core content of each unit, we organize it into questions that ask about orthodox problems and basic principles directly related to each unit, and provide a 'Jump Helper' to solidify the basics.
② You can select representative types of problems from each unit, solve them according to the solution, and then use the confirmation problems to firmly master the representative types.

③ You can prepare for various school exams and competitions by covering a wide range of new types of problems that are covered outside of the curriculum or textbooks.

④ We have carefully selected only the highest level of difficulty problems in the country, especially high-quality problems that can evaluate your problem-solving skills, so you can solve problems without fear even when participating in high-level competitions such as national competitions and the World Mathematical Olympiad.
⑤ By comparing and analyzing past exam questions for the Gifted Education Institute entrance exam and organizing and solving the essential problems, students can improve their creative thinking skills through practice similar to the actual exam and prepare for real-life problems.
