Features of this book

A textbook that thoroughly analyzes past school exam questions.
- The textbook was created based on the results of a detailed analysis of past exam questions from approximately 300 high schools nationwide, categorized by type, difficulty, and frequency of questions.
School exams vary in difficulty depending on the style of the teachers who administer the exams, but the important questions that must be assessed are the same or similar.
This textbook covers all of these important issues.

A textbook containing 19 types of questions that often appear on school records
- We selected 19 types of questions that frequently appear in school exams and academic performance assessments, and organized each type into important questions so that you can fully prepare for important problems that often appear in school grades.
Math is already difficult! You don't have to struggle to learn material that won't even appear on school exams, so you can prepare efficiently for your internal exams.

A textbook that will give you confidence in your strategy for each type.
- In three stages of [basic problems] + [previous problems] + [expected problems], you will learn how to solve problems by type through sufficient repetitive learning of the types, which will give you confidence in taking school exams.


Structure of this book

Analysis of question types
- We analyzed past exam questions from over 300 high schools nationwide and academic ability assessments to organize the question types, difficulty levels, and likelihood of questions appearing on the exam.
Each question is categorized and marked according to type and difficulty so that you can study it intensively in either the "Super Easy Internal Exam Textbook" or the "Super Important Internal Exam Textbook."

Examining the core concepts
- We have made it possible to check the essential concepts and formulas required to solve problems by type through concept confirmation.

Mastering basic problems
- We present basic problems that can be solved by applying the basic concepts of each type, or problems that allow you to practice applying the formulas directly.
It was created to serve as a basis for solving past exam questions.

Preview of past exam questions
- By presenting questions of the types that were on school exams and scholastic ability assessments, we have helped students develop adaptability to each type of question and eliminate their fear of the actual exam.

Check the expected questions
- We have provided practice strategies for each type of exam, based on basic and past exam questions, so that you can practice with similar questions from past exams.
Additionally, we have developed problem-solving skills and confidence by presenting slightly modified types.
