This learning app is specifically designed for those aiming to pass the Water Supply Installation Chief Engineer Examination. It reflects the latest legal revisions, such as the 2024 transfer of water administration (Ministry of Land, Infrastructure, Transport and Tourism and Ministry of the Environment) and the addition of PFOS/PFOA water quality standards in April 2026.

It features 649 past questions in the format of the actual exam and 807 original questions carefully selected from key points, for a total of 1,456 questions. It covers all 8 fields, from public health theory to the structure and performance of water supply equipment and construction management methods, allowing you to efficiently improve your chances of passing even through self-study.

The Q&A format allows for quick learning during spare time. The explanations for each option help you understand *why* that answer is correct.

◆ Features of this app

1. Review *before* you forget using the Forgetting Curve (FSRS)

Equipped with the memory retention algorithm "FSRS". It presents questions at the right time, based on your learning progress, so you're about to forget. This reduces unnecessary review and helps solidify knowledge into long-term memory with less effort.

2. Get used to the actual exam format with past question mode

Includes past questions in the format of the actual exam. Questions are grouped by topic, allowing you to target your weaknesses, such as "perforation of saddle-type branch valves" and "outlet space." It's separate from the original question set, so your learning records won't get mixed up. You can switch between modes at any time from the top of the screen.

3. Understand *why* with explanations for each option

Every question has an explanation for each option. Important terms are highlighted in color, making it ideal for memorization. Changes since the exam was first created, such as the transfer of water administration in 2024, have been supplemented to allow you to relearn the current system.

4. Overcoming Weaknesses Through Subject-Specific Learning

• Introduction to Public Health
• Water Administration
• Water Supply Installation Law

• Water Supply System Construction Management Methods

The learning analysis function makes it immediately clear which subjects you are strong in and which you are weak in.

5. Actual Exam-Style Test Mode

Choose from 10, 20, or 30 questions. Strengthen your practical skills with a time limit. There is also a "Random Questions" option where all questions are shuffled and solved in one go; you can resume from where you left off even if you close the app midway.

6. Overcoming Weaknesses with Review Mode

Incorrectly answered questions are automatically saved. You can repeatedly study only your weak points.

7. Review Key Points with the Web Textbook
