1.
Learning concepts and practicing past exam questions to build a solid foundation for the internal exam

We thoroughly analyzed midterm and final exam questions from middle schools across the country and based on this, we have neatly organized the core concepts with high frequency of questions by middle school level. We have also selected frequently appearing types of questions on the exams to help you focus on basic learning.
Additionally, we have structured related problems with explanations of advanced or higher-level concepts linked to the core concepts of the textbook, making it easier to solve problems requiring discrimination.

2.
Three-dimensional problem structure to achieve perfect grades

To achieve the goal of a perfect score on the internal exam, we have carefully selected highly accurate exam-predicted questions and organized them into "difficult problems for a perfect score challenge" for the upper-intermediate level and "highest level problems to reach the top" for the highest level to solidify the ability to achieve a perfect score on the internal exam, by level.
And, to help you check your skills in preparation for midterm and final exams, we have created a "School Exam Practice Test" for each unit.

3.
Intensive learning to improve creative thinking and problem-solving skills

By focusing on studying various creative types of problems, we have helped students develop creative thinking skills, and by providing problem-solving methods and systematic solutions, we have helped students improve their problem-solving skills.
