How to Pass the Divemaster Exam
The Divemaster exam is longer and more theory-heavy than anything before it. Break it into topics and it becomes very manageable.
What's on the exam
The Divemaster final exam is 120 questions — two 60-question sections — and you generally need 75% per section. It spans the five dive-theory areas (physics, physiology, equipment, decompression and the RDP/eRDPml, and the dive environment) plus dive-professional knowledge like supervising divers and standards.
Dive planning with the RDP and eRDPml is where most candidates lose points, because it demands accurate, repeatable table work. Prioritize it.
A study plan that actually works
Reading the manual cover to cover is the slowest way to prepare. The fastest is active recall: answer questions, see what you get wrong, and target those gaps. Here's the loop that works:
- Drill one topic at a time until you're consistently scoring above the pass mark on it.
- Take full, timed mock exams so exam day feels familiar, not stressful.
- Review every missed question — understanding why the right answer is right is what makes it stick.
- Practice in the language you think in, so you're testing your dive knowledge, not your translation.
Common mistakes to avoid
The usual culprits:
- Under-practicing the RDP/eRDPml — it's the single most missed topic.
- Studying passively by re-reading instead of answering questions.
- Cramming all five theory areas at once instead of mastering them one by one.
