Frequently Asked Questions
How many questions are on the USCG GLI05 exam?
GLI05 is modular for Master or Mate less than 200 GRT on Great Lakes and inland routes. Published modules include Rules of the Road (50), Deck General (50), Deck Safety (50), Navigation General GLI (50), and additional chart/navigation modules in the Q343–Q346 range.
What passing score do I need?
Most modules require 70%. Rules of the Road requires 90%. Chart plot requires 90% when a chart-plot module is assigned. Great Lakes Topics modules (when required) generally require 70%.
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. Medical, drug testing, and training 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.
What is the difference between Inland-only and Great Lakes and Inland Rules modules?
For Great Lakes and Inland routes, Rules of the Road is Inland and International (Q100). For Inland routes, applicants may take Inland-only Rules (Q300), but Inland-only Rules result in a geographic COLREGS limitation on the MMC unless Q100 is also completed (46 CFR 11.430).
Are open-book renewal exercises the same as the original modules?
Renewal open-book exercises (for example, master/mate unlimited or limited-tonnage renewal papers listed in the Deck Guide) are separate from original GLI05 knowledge modules. This bank focuses on original-module knowledge.
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The NMC policy letter of December 2, 2024 superseded the earlier TI-30XIIS-only rule.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 an English-language multiple-choice study adaptation 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.
