◆ Features of this book

* Perfect study guide for internal exams
- We have thoroughly analyzed school exam questions from across the country and organized them to help you prepare for school exams, focusing on frequently asked questions.
Additionally, we have included questions from the Office of Education's scholastic ability test that are frequently included in internal exams.

* Basic problem book designed for intermediate to upper-middle level
- All examples and practice problem types from the textbook are included, allowing students to sufficiently practice their calculation skills with the textbook's basic questions.
We have reduced the learning burden by not including top-tier questions.

* Basic problem book with various configurations for selective learning
- The composition of this textbook is [Concept Summary] + [Basic Textbook Problems] + [Internal Grade Type Problems] + [Problems that the teacher always includes on exams].
In particular, we have included many [basic problems] to ensure a solid understanding of the concepts.

◆ Structure of this book

* Concept organization
- We have made it possible to check the important core concepts covered in each unit.
Definitions of essential concepts and terms, key formulas, etc. are provided, and additional information such as formulas for deeper understanding before solving problems are provided in supplementary paragraphs.

* Basic textbook problems
- This is a corner where you can review basic concepts through basic problems at the textbook example level.
We focused on accurately understanding the core concepts of each unit by sufficiently practicing calculation problems and concept understanding problems.
Definitions and Basics of Terms
We have made it possible for you to understand the formula accurately and prepare for the type of questions on your internal exam.
* Internal type problem
- We analyzed past exam questions from over 300 high schools and categorized the frequently appearing questions into types.
Important questions are marked as 'Important' and frequently appearing questions from the Office of Education are also included.
We have developed the ability to adapt to frequently asked questions so that you can prepare for the exam.

* Questions that teachers always ask on exams
- We have selected and organized problems that frequently appear on actual exams from among various types of problems.
We have focused on solving common problems that appear on school exams, from basic to more difficult ones.
- We have selected difficult problems that must be solved to achieve a top grade in the internal exam and included two “1st grade problems” each.
By solving difficult problems with a high error rate, you can develop mathematical thinking skills and problem-solving abilities, making it possible to challenge for a top grade in your internal exam.
