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

Because we've collected and analyzed past school exam questions from middle schools across the country and organized them by type, you can perfectly complete your middle school math studies with just one book, Sen Math.

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 B-level Type Breakdown, 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 to be covered in Middle School Mathematics 3-1 are categorized into 171 types and organized into 1,398 problems, allowing for sufficient practice by type and developing problem-solving skills.
