*Certified for both Class 1 and Class 2 Occupational Health and Safety Manager Certification

The lecture videos and practice problems for this course were created in April 2026.

While both the above cover important points from past exams, some content may not be up-to-date with the latest exam depending on when you take the course or exam.

[Lecture Videos Condensing the Expertise of Professional Instructors]
Instructors who are experts in occupational health and safety managers explain the key points for passing the exam in an easy-to-understand manner, covering topics such as occupational health and related laws and regulations.

Each video is approximately 10 minutes long, making it easy to study for the occupational health and safety manager certification during short breaks, such as during your commute.

[Thorough Analysis of Past Occupational Health and Safety Manager Exam Questions! Practice Problem Function]

Thorough analysis of past exam question trends in occupational health and related laws and regulations!

These are original questions created by instructors who are experts in occupational health and safety managers.

The questions are categorized by difficulty level, including simple true/false questions to check basic knowledge, and multiple-choice questions in the same format as the actual exam, allowing even beginners to gradually improve their skills.

[Efficient Input Through a Lecture → Problem-Solving Cycle]
When you want to review the content of a lecture you've already seen, "Lecture Slides" are incredibly useful.
You can review the slides used in the lecture video as still images.
Also, solving problems immediately after watching a lecture is a golden rule of exam preparation.
With Onsk, you can immediately challenge yourself with problems on that topic using a button within the lecture video.

[Progress Management is Manageable with the App!]
You can manage the content you're studying in "My Page." You can check your "Progress Rate" and "Correct Answer Rate." Since you can see the progress rate and correct answer rate for each topic, your current abilities and weak areas are immediately clear. Furthermore, you can extract only the "Problems You Got Wrong" or "Bookmarked Videos/Problems" and try them again.

[Take a Break When You're Tired of Studying! Plenty of Free Content such as "Helpful Videos" and "Magazines" are Available]
Onsk's approach goes beyond just studying for qualifications.
