USCG Exam Format — Modules, Pass Marks, and Time Limits

The USCG written exam is module-based. Each module is a separate timed test scored independently, with its own pass mark. Failing one module does not require re-taking the others.

TL;DR

OUPV: 4 modules (RoR @ 90% pass, others @ 70%, ~3.5 hours total). Master: same 4 + Plotting (chart-work) + General. Exam taken at any USCG REC or USCG-approved third-party course with exam authority.

Modules and pass marks

Rules of the Road: 30 questions, 90% pass mark (27/30). Deck General: 70 questions, 70%. Deck Safety: 70 questions, 70%. Navigation General: 70 questions, 70%. Plotting (Master only): 10 questions on a chart, 90% pass mark for the strict version. General (Master only): 70 questions, 70%.

Where to take it

USCG REC (one of 17 nationwide) — the original-issue exam. USCG-approved third-party schools — many issue exam authority on completion of a course, allowing the candidate to test at the school instead of the REC.

Re-taking modules

Failed modules can be re-taken after a 14-day waiting period. After three failures on the same module, you must wait 90 days and re-prove competency.
