1.
The optimal problem-solving textbook to reduce learning burden
It is structured to cover the essential concepts for each topic in detail and to allow sufficient practice of basic types.
By boldly omitting difficult content, questions that are rarely tested, or questions that do not fit recent test trends, we have reduced the learning burden and improved the learning achievement of students who struggle with math.

2.
Type segmentation
After covering all the easy school exam questions, we've broken them down into more specific types based on the concepts and solution methods needed to solve them, so you can learn problem-solving strategies for each type.

3.
three-dimensional learning
The difficulty of the problems is divided into two levels, A and B. By strengthening the basic problems of level A and further dividing the types of level B, three-dimensional learning is possible by level of difficulty and type.

4.
Perfect preparation for real-life situations
We have designed the final study questions for each unit based on frequently appearing questions in school exams to check the learning level of each unit, and we have provided a final check through mock exams for each unit in the format of actual exam papers to ensure perfect preparation for the actual exam.
