About this app

Passing the Class 2 Electrical Engineer Examination (Power) requires consistent and correct practice.

The "Power" subject of the Class 2 Electrical Chief Engineer Examination covers a wide range of topics including power generation, transformation, transmission, and distribution, making it difficult to reach a passing level without extensive practice with past questions.

This app is a learning app that contains past questions for the Class 2 Electrical Engineer Examination (Power) subject in a "question and answer" format. Open, solve, and read the explanation. These three steps can be completed anytime, anywhere, using only your smartphone.

▼ Features of this app
● Stress-free operation that lets you start the moment you open it

This app prioritizes "ease of starting" learning. You can begin practicing problems immediately after launching the app. With a simple, intuitive UI, you can solve problems, check explanations, and move on to the next problem. There is no waiting time in this entire process. You can reliably progress through practice even in a few minutes during your commute, lunch break, or short time before bed, making it an ideal app for busy people.

● Detailed and well-reasoned explanations for all problems
Simply checking whether an answer is correct or incorrect won't give you the skills needed for the actual exam. This app, developed by someone who has passed the Class 1 Electrical Chief Engineer Examination, provides step-by-step explanations of the thought process behind each answer, including background knowledge of related laws and formulas. Beginners can understand "why" things are the way they are, and advanced users can use it to check for gaps in their knowledge.

● "Unlearned/Review" function allows you to review only incorrect or unstudied problems
The app automatically records incorrect answers, allowing you to focus on and rework only the problems you struggle with. Instead of blindly repeating all problems, you can pinpoint your weaknesses, making the most of your limited study time.

● Bookmark function for quick access to important problems
You can bookmark problems you're interested in or want to review repeatedly, allowing you to access them anytime. Whether you want to review them thoroughly later or check them again right before the exam, you can easily find the problem you're looking for.

● Efficient Knowledge Retention Through a Question-and-Answer Format
By repeatedly going through the "question → answer → explanation" cycle in a short amount of time, you can solidify your memory. Compared to passively reading a textbook, this provides a more rewarding learning experience in the same amount of time.
