● Book Introduction
This book is the first electrician book written from the perspective of a non-major. This was made possible thanks to numerous reviews and outstanding researchers.
The features of this book are as follows.
1. For the first time in the previous problem collection for electricians, the problem collection and the commentary collection were separated.
2. You can check the frequency of questions through ★, so you can study important questions efficiently.
3. Increase learning efficiency with detailed explanations that do not require re-finding the concept book.
4. MATH means the unit of 'YouTuber's Combat Math'. Since the electrician test requires knowledge of mathematical concepts in many cases, the section on combat mathematics is written in the commentary for questions containing mathematical concepts.
5. Difficulty means very difficult questions, and if your goal is to pass an electrician, you can skip it.
6. 'Memorize' is a question that can be solved by memorizing the answer without having to understand the derivation process.
