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. Some raise-of-grade or no-exam paths use evaluation plus issuance only (sometimes cited around $110+$45). Medical, drug testing, and training costs are separate. Confirm current NMC fees and pay via Pay.gov.
Can I take the exam remotely?
No. These 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 Barge Supervisor the same as Ballast Control Operator?
No. Barge Supervisor is NMC path MODU02 under 46 CFR 11.472. Ballast Control Operator is a separate endorsement (MODU03 / 46 CFR 11.474) with its own modules and subject matrix under 46 CFR 11.920 column 7.
What regulation covers Barge Supervisor?
46 CFR 11.472 sets service and training requirements for the national Barge Supervisor endorsement. Examination subjects for MODU endorsements, including Barge Supervisor (code 6), are listed in 46 CFR 11.920.
Do unlimited Masters take the same exams?
NMC checklists note that holders of unlimited Master may have reduced or waived exam requirements when other 11.472 training and service items are met. Always confirm the current NMC Barge Supervisor checklist for your credential status.
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The NMC policy letter of December 2, 2024 superseded the earlier TI-30XIIS-only rule.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 differ in wording, figures, and open-book renewal format from this bank.
