Frequently Asked Questions
How many questions are on the USCG TV02 exam?

Published modules include Rules of the Road International and Inland (Q100), Deck General (Q418 — 70 questions at 70%), Deck Safety (Q419 — 70 questions at 70%), Navigation General Great Lakes and Inland (Q420 — 50 at 70%), Chart Plot (Q421 — 10 at 90%), and TV GLI Renewal OBE (Q422 — 50 at 90%) for renewal. Exact totals depend on the current NMC module sizes; confirm sample exams on the TV02 NMC page.
What passing score do I need?
Most modules require 70%. Rules of the Road (Q100) requires 90%. Chart Plot (Q421) requires 90%. TV GLI Renewal OBE (Q422) requires 90% when assigned for renewal.
How much does the exam cost?
Under 46 CFR 10.219, a typical original lower-level officer path is about $100 evaluation, $95 examination, and $45 issuance (~$240 total). Medical, drug testing, TOAR-related training, and firefighting course costs are separate. Pay via Pay.gov.
Can I take the exam remotely?
No. These deck officer modules are administered in person at U.S. Coast Guard Regional Exam Centers (RECs). There is no approved remote-testing option for these endorsements.
Is TV02 the same as Oceans/Near Coastal or Western Rivers towing exams?
No. TV02 is Master/Mate/Apprentice Mate of Towing Vessels on Great Lakes and Inland routes. Oceans or Near Coastal towing uses a different NMC path (uscg-master-mate-towing-oceans-nc). Western Rivers towing uses uscg-master-mate-towing-western-rivers. Do not mix route-specific modules or assume one credential covers the other route.
What regulations cover Master, Mate, and Apprentice Mate of towing vessels?
46 CFR 11.463 (Master of towing vessels), 11.464 (Mate/pilot of towing vessels), 11.465 (Apprentice mate/steersman), and related provisions including 11.466 address towing endorsements. Confirm sea service, TOAR, and examination requirements on the current NMC checklist for the GLI route.
Is Q422 part of the original knowledge exam?
Q422 is the TV GLI Renewal open-book exercise (OBE). Original issuance typically uses Q100 and Q418–Q421 as assigned. Renewal open-book exercises are separate from original knowledge modules.
What calculator can I bring?
The NMC policy letter of December 2, 2024 superseded the earlier TI-30XIIS-only rule. At a Regional Exam Center you may use a programmable calculator with memory if all programs and memory are cleared before entry and you can demonstrate clearing with the manufacturer's instructions. If the examiner cannot confirm the device is cleared, a TI-30XIIS is provided instead. Only one calculator is allowed; other electronics including smart watches are not permitted.
Is this free practice bank an official Coast Guard exam?
No. This is a free English-language multiple-choice study aid for exam prep. Official modules are administered by the Coast Guard at RECs and may include chart-plot and calculation items that this bank approximates with knowledge and calculation MCQs.
