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

By analyzing past high school exam questions from across the country, past exam questions from the Evaluation Institute and the College Scholastic Ability Test, as well as numerous basic textbooks, school exam books, and college entrance exam books, all math problems were collected and classified to create a powerful type network, so that sufficient practice problems can be obtained with just one book.


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.


Presenting three-dimensional and detailed types by concept

Problems arising from a single concept appear in various types.
All problems that must be covered in high school are classified into 182 types and organized into 1,327 problems to enable sufficient practice by type, thereby developing problem-solving skills.
