Frequently asked questions
Straight answers about the DMT exam, the questions, pricing, the free trial, and how this fits your prep.
The DMT exam spans 7 domains - Physics and Physiology (7.5%), Decompression Sickness & Cerebral Arterial Gas Embolism (15%), Patient Assessment (25%), Recompression Treatment & Decompression Procedures (22.5%), Invasive Procedures (10%), Other Diving Related Injuries, Side Effects & Complications (15%), and Chamber, Equipment and Operational Safety (5%). Every practice question maps to one of them, so you train on exactly what's tested.
The Diver Medic Technician (DMT) exam has 120 questions and is completed in 2 hours. Our timed practice tests mirror that length and pacing, so exam day feels familiar.
No - and that matters. These are original practice questions written to mirror the style, difficulty, and domain coverage of the DMT exam blueprint. We never distribute actual exam content, so practicing here keeps you fully compliant with official exam policies.
No. DMT Exam Prep is an independent study resource for Diver Medic Technician (DMT). It is not affiliated with, sponsored by, or endorsed by the official certifying body or exam administrator.
Every paid plan unlocks the full bank of 1,000+ practice questions covering all 7 DMT domains - Physics and Physiology (7.5%), Decompression Sickness & Cerebral Arterial Gas Embolism (15%), Patient Assessment (25%), Recompression Treatment & Decompression Procedures (22.5%), Invasive Procedures (10%), Other Diving Related Injuries, Side Effects & Complications (15%), and Chamber, Equipment and Operational Safety (5%). You can practice the whole bank, filter by domain, or run a timed, domain-balanced exam simulation.
Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.
Yes. You get 10 free sample questions with instant feedback - no credit card and no account required.
The free sample shows you the question quality. Paid plans unlock the full 1,000+ question bank, exam-style practice modes, mistake review, and - on Fast Track and Pass Confidence - progress analytics that show your readiness by domain.
No. Every plan is a single one-time payment for a fixed access window - 48 hours, 7 days, or 6 weeks. There is no auto-renewal and no recurring billing.
Match it to your exam date: Final Review (2 days) for an exam in the next day or two, Fast Track (7 days) for an exam this week, Pass Confidence (6 weeks) for a structured run-up.
For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.
Chat with us any time - the 24/7 support chat in the corner of every page gives instant answers about plans, access, and billing. Prefer email? The contact link is in the footer. Payments are processed securely by Stripe, and active customers can download an invoice from their profile page.
Make sure you're signed in with the same email you used at checkout - access activates within a minute of payment. If it still doesn't appear, email us from the contact link in the footer and it'll be sorted out.

Real feedback from DMT candidates on Reddit.
"put off studying till like 2 weeks out and panicked a bit. did the practice questions on dmttest.com every night after shift and the patient assessment stuff finally clicked. passed first try, still kinda surprised tbh."
"honestly wasnt sure a generic emt background was gonna cut it for the dive specific stuff. the mock exams helped alot, especially the recompression and decon procedure sections since thats what i kept missing in my own notes. got thru it fine."
"studied on and off for a month, mostly on breaks at work. the mistake review feature showed me i kept blowing the DCS and gas embolism questions so i just drilled those over and over. passed with time to spare on the actual test."
