About this app

For the Electrician Technician written exam, reviewing necessary content in a timely manner is more important than solving a large number of problems.

Prepare for the three subjects of Electrical Theory, Electrical Machinery, and Electrical Installation in one app. It includes custom-made questions and detailed explanations for each subject, and FSRS calculates the next review time based on your memory status for each question.

[Key Features]

Full-range learning by subject
**Learn the three subjects of Electrical Theory, Electrical Machinery, and Electrical Installation by dividing them into subjects and units.** Progress and accuracy rates are displayed for each unit, allowing you to identify and focus on areas you haven't touched yet or your weak points.

Custom-made questions and detailed explanations
**We have included study questions across all units tailored to the exam scope and the 4-option multiple-choice format. To ensure you don't just check the answer and move on, we have explained why that answer is correct and why the other options are incorrect.

**Mock Exams**
**Planned to solve 60 questions within 60 minutes, allowing you to practice time management and choosing which questions to skip. You can check your results against the passing standard of a total score of 60 points or higher. After solving the problems, you can review your scores by subject and the questions you got wrong all at once.
