This book, which was created so that students can sufficiently prepare for mathematical ability through self-study, is an optimized textbook for studying applied mathematics for the public enterprise NCS basic job ability assessment and the aptitude test for large corporations. It was created for test takers who have difficulty or are lacking in studying public enterprise NCS mathematical ability due to the small number of problems and poor explanations in the few NCS applied mathematics workbooks available on the market.
This study guide provides a total of 503 questions, including "33 Pre-Level Tests," "400 Daily Questions for Self-Study," consisting of 33-34 questions each for 12 days, and "70 High-Difficulty Questions by NCS Applied Mathematics Type."
The main features are as follows:

NCS Applied Mathematics provides detailed explanations and explanations, with illustrations, to the point where each problem is approximately one A4 page long. Each problem is accompanied by two to three explanations, offering a variety of approaches to understanding, making it accessible even to beginners. NCS Applied Mathematics is divided into three difficulty levels (Levels 1 through 3) with varying levels of difficulty, allowing for daily practice as if in a real-world situation.
A unique feature of this book is that it can be completed in a short period of 14 days through the learning order of “calculation practice → practical solution → 70 difficult problems by type.”
Current public enterprise employees and current and former students of Seoul National University, Korea University, Yonsei University, and Pohang University of Science and Technology (POSTECH) intensively analyze applied mathematics problems frequently appearing in public enterprise NCS mathematical ability tests, providing the most effective learning experience, including practical know-how (tips) from successful candidates.
Therefore, even if you study on your own, you can feel the effect of receiving private tutoring from someone who passed the exam.
