Unlimited Divemaster practice exams across all of dive theory — physics, physiology, equipment, decompression, the RDP/eRDPml, plus supervising divers and standards. Fresh questions every attempt.
The Divemaster final exam is a 120-question test — two 60-question sections — spanning dive theory and dive-professional knowledge. Our engine drills each dive-theory area separately (physics, physiology, equipment, decompression, dive planning) and then builds full mock exams, so you master every section before test day.

A taste of the style and difficulty. In the app you get a fresh set every time.
Compared with salt water, fresh water requires a diver to descend slightly deeper to add each additional bar of pressure. This is because fresh water:

When supervising a group of certified divers, a Divemaster's primary responsibility is to:
Why: A Divemaster evaluates the site and conditions, briefs the divers, and actively manages the dive to keep everyone safe.
The Divemaster final exam is 120 questions, split into two 60-question sections, and you generally need 75% per section. Our practice exams generate fresh 60- and 120-question sets on demand.
Take one topic at a time — physics, physiology, equipment, decompression/RDP, and environment — using focused quizzes, then sit full mock exams. Your missed questions collect into a personal review set.
Yes. Decompression theory and dive planning with the Recreational Dive Planner and eRDPml are a dedicated topic in the Divemaster practice set.
