We thoroughly analyzed and classified questions from midterm and final exams, mock exams, and the College Scholastic Ability Test across the country, dividing them into detailed types to help you master all types of mathematics.
All problems of each type are classified by difficulty.
The entire structure is divided into 5 levels, and among these, Type Mastery and Type Up are subdivided into 5 levels of difficulty: low, medium-low, medium, medium-high, and high, allowing for systematic improvement of mathematical skills.
Essential examples of conceptual mathematics are typified.
Essential examples from the basic mathematics textbook on concepts and principles are categorized and various problems are included for each type to help students develop application and problem-solving skills.
Therefore, if you study in conjunction with the basic mathematics textbook on concept principles, your learning effect will be even greater.
