① Concept organization and type classification faithfully reflecting the 2022 revised curriculum
② Maximize learning effectiveness with a three-level learning system (A, B, C).
③ Includes the latest national internal exam questions, allowing you to prepare for frequently appearing and new types of questions.
④ Includes excellent past college entrance exam questions to improve convergent thinking skills.

1.
All the questions that appear on the exam are in this one book.

We have collected and classified all math problems by analyzing past high school exam questions, past exam questions from the National Institute of Curriculum and Evaluation, and past exam questions from numerous textbooks, internal exam books, and college entrance exam books, and created a powerful type network, so you can sufficiently practice problems with just one book.


2.
All problems are divided into 3 difficulty levels: A, B, and C.

A reasonable way to learn math is to tackle problems in order, from easy to difficult.
Strong Math divides all problems into three levels and organizes them by level. In the Type Breakdown section, these are further divided into easy, medium, and high difficulty levels to systematically develop math skills.


3.
Presenting three-dimensional and detailed types by concept

Problems arising from a single concept can appear in many different types.
All problems that must be covered in high school are categorized into 92 types and organized into 719 problems, allowing for ample practice for each type and developing problem-solving skills.
