About this app

For the first stage of the Industrial Safety Instructor exam, it is more important to review necessary content in a timely manner than to solve a large number of problems.

Prepare for the three subjects—Industrial Safety and Health Act, General Industrial Safety, and Corporate Diagnosis Guidance—all in one app. It contains 375 past exam questions from the last five years, along with custom questions organized by unit, and includes explanations for each question detailing why the answer is correct. The app selects what to review today based on your memory status for each question.
