『2025 OneQ Pass Samsung Job Aptitude Test GSAT Level 5 High School Graduate Recruitment (Previous Questions + 5 Mock Tests)』 is a textbook for preparing for the GSAT Level 5 High School Graduate Recruitment Aptitude Test.
You can familiarize yourself with past exam questions by completing 690 questions, and you can study for the actual exam with a total of 5 mock exams.
It also provides easy and quick solution methods and learning strategies so that you can study on your own.
This book was written by a team of expert writers who have developed aptitude tests for various large corporations for many years, thoroughly analyzing the types of questions from past GSAT exams, focusing on the key points for each type.

In PART 1, we organized the representative types of each type of mathematical logic and reasoning, and described in detail the solution methods for each type to shorten the time in the actual exam.
Detailed explanations of particularly difficult spatial perception problems, along with detailed explanations for each type, enhance learning comprehension. Part 2 includes five mock exams, allowing ample practice with the questions. The Answer and Explanation sections provide explanations for correct and incorrect answers for each question, along with solutions tailored to the specific characteristics of each question and applicable to actual exams.

The GSAT is not a test where you have to answer every question correctly.
If you assume that problem 1 is a problem that takes a long time to solve, you took your time and solved it well, but if you think about it differently, you would have been more competitive if you had solved two easier problems in that time.
This book is designed to train you in quick solutions to each representative type of question.
I am confident that if you understand and organize the concepts with your own principles by referring to the solutions in this book, you will be able to achieve the result you desire: passing the exam.
