A problem-solving book that makes math easier

Features of this book

1.
Faithfully reflects the 2022 revised curriculum
2.
A 3-step learning system (basic, type, and final) allows for easy and complete learning.
3.
Includes the latest national internal exam questions to help you prepare for frequently appearing and new types of questions.

1.
Problem-based textbook that reduces learning burden

It is structured to cover the essential concepts for each topic in detail and to allow sufficient practice of basic types.
We've removed unnecessary content and lowered the difficulty level of difficult textbook-covered topics and frequently appearing on school exams to reduce the learning burden and ensure adequate exam preparation.

2.
Systematic & three-dimensional learning

The difficulty of the problems is divided into two levels, A and B, and level B is further subdivided into levels of difficulty, B-, B0, and B+, to systematically develop mathematical skills.
In addition, in Stage A, we provide the basic problems essential for learning the concepts, and in Stage B, we provide a variety of problems by type to enable three-dimensional learning.

3.
Improve problem-solving skills through detailed type learning.

We've compiled a comprehensive collection of easy-to-find school exam questions, the College Scholastic Ability Test (CSAT), the Korea Institute of Curriculum and Evaluation (KIET), and past exam questions from the Office of Education. We've broken them down by type, based on concepts and solution methods needed to solve the problems, so you can learn problem-solving strategies for each type.

4.
Final study of the intermediate level to prepare for the real exam

We've designed a set of final study questions for each unit that reflect the latest exam trends, allowing you to review your learning for that unit and fully prepare for the actual exam.
