Full CBT mock exams for MEO, STCW, GATE Naval Architecture and PMP — written by working marine professionals, with an explanation on every single question.
Every rung is an exam. We prepare you for the next one.
Topic-wise sets and full-length mocks in a real CBT interface — timer, question palette, review marking.
Watchkeeping engineer COC. Thermodynamics, boilers, IC engines, auxiliaries, refrigeration, electricals, automation, stability and legislation — plus operational and oral prep sets.
Start practicing →Second engineer COC. Advanced thermodynamics, propulsion plant performance, fault diagnostics and condition monitoring, power management, UMS automation, EEXI/CII and management-level orals.
Start practicing →Chief engineer COC. Plant heat balance, main engine management, HV electro-technology, surveys and class, operation and cost management, safety systems and leadership — eleven chapter briefs, with question sets to follow.
Read the briefs →Deck officer certificates of competency under STCW II/1 and II/2. Navigation and COLREGs, cargo work, stability and damage control, ship handling, meteorology, GMDSS, maritime law — and oral preparation at every level.
Start practicing →STCW III/6. Power generation and distribution, high voltage systems and safety, motors and variable frequency drives, PLC and automation, power electronics, and maintenance of navigation and communication equipment.
Start practicing →SOLAS and LSA, fire prevention and firefighting, MARPOL Annexes I–VI, medical first aid, PSSR, ISPS, watchkeeping and BRM, emergency procedures and ISM.
Start practicing →Hydrostatics, stability, resistance, propulsion, ship structures, vibration, marine systems, design and production, ocean engineering, engineering mathematics and aptitude.
Start practicing →The NCEES professional engineer exam. Thirteen knowledge areas weighted as the specification is — hydrostatics and stability, structural design, hydrodynamics, propulsion, piping, auxiliaries, electrical, environmental, outfitting, materials and regulations.
Start practicing →Situational practice built for the July 2026 exam content outline, in which Business Environment rose from 8% to 26% and AI, sustainability and business value entered the paper. Twelve topics across all three domains. About half the scenarios are drydockings, retrofits and offshore campaigns.
Start practicing →Pick a topic and sit a focused set in the real CBT interface. No payment to start.
Each question carries a written explanation — including why the tempting wrong options fail.
Scores are saved so you can watch weak topics turn strong before the real thing.
Deephull Academy is run by the same people who build ClassCode AI and Stability Master — practising naval architects and marine engineers. Questions are drafted, reviewed and argued over by people who work in this industry every day.

Function-wise syllabus, the assessment stage, and the three mistakes that cost most candidates marks.
Read it →What changes from Class 4 — and why depth is not the axis the exam moved along.
Read it →The 2027 syllabus was revised in July 2026. Paper structure, marking and every syllabus area.
Read it →The oral fails more candidates than the written papers, and rarely through ignorance.
Read it →Time aboard and qualifying sea service are two different things. Most people find out too late.
Read it →An expired short course can stop you sailing on a perfectly valid certificate of competency.
Read it →Written explanations of the topics that cost most people marks — free, no account needed.
Spaced repetition, active recall and error logs — built around watch routine instead of against it.
Read it →What examiners actually ask about lube oil, and the answers that separate a pass from a fail.
Read it →Fire triangle, extinguishing media and the fixed installations — the parts that appear every sitting.

Yes. Every topic-wise mock test is free to sit, and you get the full explanation on every question afterwards. You need an account only so your scores can be saved to your progress page — there is no card and no trial clock.
MEO Class IV and MEO Class II (Marine Engineer Officer certificates of competency), STCW and safety, and GATE Naval Architecture and Marine Engineering. Each exam is broken into topic-wise sets so you can practise one weak area at a time rather than sitting a full paper every session.
It's built to the same conventions: a countdown timer, a numbered question palette that colour-codes answered, seen-but-unanswered and flagged questions, mark-for-review, and free navigation between questions. The point is that on exam day the software is the one thing you aren't thinking about.
Your answers, flags and remaining time are saved in your browser as you go. Reopen the same test and you carry on from where you were rather than starting again.
Your progress page ranks every topic you've attempted by average score, weakest first, and links straight into a fresh test on the topic costing you the most marks.
Practising marine engineers and naval architects — the same people who build Deephull's engineering software. Every question carries a written explanation, including why the plausible wrong options are wrong.
