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 approved courses 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 TV01 the same as Great Lakes and Inland or Western Rivers towing?
No. TV01 is Master, Mate, and Apprentice Mate of Towing Vessels on Oceans or Near Coastal routes. Great Lakes and Inland towing uses TV02 (uscg-master-mate-towing-gli). Western Rivers towing is a separate path (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 covers Master of towing vessels; 46 CFR 11.464 covers Mate of towing vessels; 46 CFR 11.465–11.466 cover Apprentice Mate (Steersman) of towing vessels. Confirm current NMC checklists for Oceans or Near Coastal service and TOAR requirements.
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The NMC policy letter of December 2, 2024 superseded the earlier TI-30XIIS-only rule.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.
What is Q417?
Q417 is the TV Oceans/Near Coastal open-book renewal exercise (OBE), typically 50 questions at 90% when assigned for renewal paths. Original applicants focus on Q100 and Q410–Q416 knowledge modules as listed on the current NMC TV01 page.
