Questions

Questions candidates ask about Chart Plotting

How many Chart Plotting questions are on the exam, and how many can I miss?
10 questions, 1 wrong allowed, 90% to pass. Your Approval to Test letter assigns the modules; it is the final authority on what you sit.
Is the Chart Plotting paper identical for OUPV and Master under 100 GRT?
The subject is the same and the NMC code differs by route: Q172 / Q358 on the OUPV papers. A Master under 100 GRT candidate is graded within the 210-question series at 70% and the NMC publishes no per-module mark for that route.
Where do the Chart Plotting answers come from?
Running fixes, set and drift, danger bearings. Every answer on this site opens with the regulation it tests and links to the text — 33 and 46 CFR, the COLREGs and Inland Rules, or Bowditch. If a citation ever stops resolving, the question leaves rotation.
Are these the real exam questions?
No, and nobody who says otherwise has them: the NMC does not publish its question bank. These are written to the same modules, topics and format, each one checked against the primary text by a separate model before it is published.
