(1) Classification of problems by representative type rather than a simple listing of past questions
Rather than repeating similar questions from past exams, we have carefully selected and included only essential questions for each representative type.

(2) Includes modified versions of previous exam questions and restored CBT questions reflecting the latest exam trends.
The written exam for the electrician is conducted in the form of a computer-based test (CBT), so the questions are not disclosed.
Our team of experts, including master's and doctoral degree holders, university professors, and engineers, have invested significant time into including modified and restored CBT questions reflecting the latest exam trends in our textbooks.

(3) Includes the most detailed and friendly commentary of all time
We developed this to help you understand related concepts and develop application skills through problems by including step-by-step explanations of “problem type → difficulty level → approach point → terminology check or formula check → explanation → related concept or application.”
