Structure of this book

(1) 100 questions restored from the latest exams

This book consists of 100 questions restored from the actual exam that was used in the online SKCT written exam conducted for the first and second half of 2024.
Here, we provide two special lectures on solving past exam questions (data interpretation/creative mathematics) and four special lectures on revival for those who failed the exam to help you study more effectively.

(2) Representative type analysis

It is structured so that you can gradually learn the five areas covered in the online SKCT: language comprehension, data interpretation, creative mathematics, language reasoning, and sequence reasoning.
By dividing the types by area, we have organized them into 7 types of language comprehension (finding topics and titles, agreement/disagreement, inference, paragraph arrangement, sentence insertion, case selection, response and criticism), 2 types of data interpretation (data interpretation, data calculation), 6 types of creative mathematics [four basic operations, distance/speed/time, cost (discounted price/regular price), concentration and ratio, amount of work, number of cases and probability], 7 types of language reasoning [propositional reasoning (syllogism, Venn diagram, 3 or 4 premises & 2 conclusions), conditional reasoning (truth game, matching, ordering, number of cases)], and 2 types of sequence reasoning (numbers, pictures).
You can grasp the latest trends through analysis of field characteristics, representative types, and past questions, and it is structured so that you can systematically learn representative types through stages of example learning for each representative type in each field.
Additionally, we have improved learning efficiency by shortening the time, organizing access skills, and organizing related theories.

(3) 4 mock exams

This is a set of four mock exams consisting of a total of 100 questions in five areas: language comprehension, data interpretation, creative mathematics, language reasoning, and sequence reasoning.
We provide an online testing service so that you can take all of these tests online, allowing you to practice as if you were taking the actual exam in an online testing environment.
We even provide a performance analysis service here so you can assess your position.

(4) In-depth competency test

SK's unique personality test types, which are broadly divided into two types, are included in one set so that you can practice sufficiently before taking the actual test.
