Six study modules, the real NMC codes, and a question you can answer right now. Every answer names the rule it tests: 33 & 46 CFR, the COLREGs, Bowditch.
Practise by module
Six study modules. The paper you sit combines some of them — pick your route and the map further down shows which.
Steering and sailing rules, lights and shapes, sound and light signals, and the inland variations.
Boat handling, stability, mooring, knots and equipment. Combined with Deck Safety on the OUPV paper.
Firefighting, man overboard, distress signalling, PFDs and EPIRBs.
Charts, tides, currents, magnetic variation and aids to navigation.
Its questions appear inside Deck General and Navigation on every route. We drill it separately because they miss for their own reasons.

Where the OUPV combines deck general and deck safety into one Q170 module, ONC06 splits them into Q160 and Q161 — which is why a Master candidate sits 5 modules against the OUPV's 4. An OUPV holder raising grade is commonly assigned the combined Q165 Navigation-Deck General-Safety module instead of the full original sequence. The NMC publishes no per-module question count or pass mark for ONC06, so none is stated here — your Approval to Test letter is the authority.
Credential background: Master 100 Ton and Master 25 Ton.
The topic drills below split Deck General and Deck Safety into separate study lanes, which matches the Master ONC06 split (Q160 / Q161) rather than the OUPV's combined Q170 or Q356.
The standard original OUPV exam has 160 questions across four modules: 50 Rules of the Road, 50 Deck General/Safety, 50 Navigation General, and 10 Chart Plot questions. Your Approval to Test letter controls the exact modules assigned to you.
Rules of the Road and Chart Plot require 90 percent. Deck General/Safety and Navigation General require 70 percent. That allows 5 misses on a 50-question Rules module and only 1 miss on the 10-question Chart Plot module.
OUPV Near Coastal uses ONC07. Great Lakes/Inland uses GLI07, with Q100 combined Rules or Q300 Inland-only Rules depending on the route assigned. Use the module list on your Approval to Test letter as the final authority.
No — they are different exam codes with a different number of modules. A Master under 100 GRT Near Coastal candidate sits ONC06: five modules, Q100 Rules of the Road, Q160 Deck General, Q161 Deck Safety, Q162 Navigation General Near Coastal, and Q163 Chart Plot. An OUPV Near Coastal candidate sits ONC07: four modules, because the Master exam's Q160 and Q161 are split where the OUPV combines them into a single Q170 Deck General/Safety module. Only Q100 Rules of the Road is literally the same module on both. An OUPV holder raising grade to Master under 100 GRT is commonly assigned the combined Q165 Navigation-Deck General-Safety module instead of repeating the full original Master sequence.
Every module set on this site is free and public — there is no download, no PDF paywall, and no sign-up needed to read a question, its correct answer, and the rule it tests. Each question renders as ordinary text on the module page, so your browser's print or save-as-PDF command produces a printable set. Nothing here is an official USCG question bank: the Coast Guard publishes sample exams per module on the NMC exam-code pages, and your Approval to Test letter is the authority on which modules you actually sit.
