Is the Divemaster Exam Hard?
The honest answer: it's the most theory-heavy exam you'll have taken as a diver, but it is very passable with the right preparation. Here's what actually makes it feel hard — and how to defuse each part.
What makes it feel harder than earlier exams
Three things. It's long — 120 questions across two sections. It goes deeper into dive theory than Open Water or Advanced ever did, across five subjects. And it includes dive-planning work with the RDP and eRDPml that demands accurate, repeatable table skills. None of these are hard in isolation; together they're just more than candidates are used to.
The part that trips most people up
Dive planning — the RDP and eRDPml — is where the majority of lost points cluster. It's not conceptually difficult, but it's unforgiving of sloppy procedure: a mis-read row or a wrong rounding turns a right answer wrong. The good news is that it's the most practisable topic of all, so it's the one where practice pays off fastest.
How to make it manageable
Break the mountain into five hills — the dive-theory subjects — and master them one at a time rather than facing all of it at once:
- Drill each subject until you're consistently scoring above the pass mark on it.
- Give dive planning extra reps; it's the highest-value, highest-miss topic.
- Take full timed mocks so 120 questions feels routine, not daunting.
What you need to pass
You generally need around 75% per section, and you'll typically have a chance to review any area you fall short on. So the goal isn't perfection — it's steady, comfortable competence across the five subjects. Candidates who practise to consistently clear the pass mark walk in calm.

Frequently asked questions
Is the Divemaster exam hard?
It's the most theory-heavy dive exam most people have taken, but it's very passable with preparation. What makes it feel hard is its length (120 questions), the depth of the five dive-theory subjects, and the dive-planning work — not any single difficult concept.
What is on the Divemaster exam?
A 120-question dive-theory exam across five subjects — physics, physiology, equipment, decompression and the RDP/eRDPml, and the dive environment — plus dive-professional knowledge like supervising divers and standards.
What score do you need to pass the Divemaster exam?
Generally around 75% per section, and you usually get the chance to review any topic you fall short on. Aim to score comfortably above the pass mark on practice exams before the real thing.
What's the hardest part of the Divemaster exam?
Dive planning with the RDP and eRDPml. It isn't conceptually difficult, but it's procedure-sensitive — a small table-reading or rounding slip changes the answer. It's also the most practisable topic, so targeted practice fixes it fastest.
