What is the GMDSS practice test?

The GMDSS practice test prepares candidates for the FCC Global Maritime Distress and Safety System license exams, primarily Element 7 (GMDSS Operator) and Element 7R (Restricted Operator). It covers radio regulations, distress procedures, satellite communications, and equipment operation based on ITU and IMO standards used aboard SOLAS vessels.

What is the format of the FCC GMDSS exam?

The FCC GMDSS exam is a written multiple-choice test administered by a Commercial Operator License Examination Manager (COLEM). Element 7 contains 100 questions drawn from a public question pool of roughly 600 items, while Element 7R (Restricted) contains 50 questions covering a smaller subset focused on Sea Area A1 operations.

How many questions are on the GMDSS Operator exam?

Element 7 (GMDSS Operator License) has 100 multiple-choice questions, and Element 7R (GMDSS Restricted Operator) has 50 questions. Candidates pursuing the full Maintainer endorsement must also pass Element 9, which adds another 50 questions on electronic theory, troubleshooting, and at-sea repair of GMDSS equipment.

What is the passing score for the GMDSS exam?

Candidates must score at least 75 percent to pass each FCC GMDSS element. That means 75 of 100 correct on Element 7, 38 of 50 on Element 7R, and 38 of 50 on Element 9 for the Maintainer endorsement. Failed elements can be retaken, though some COLEMs require a waiting period.

What topics are covered on the GMDSS test?

Topics include DSC (Digital Selective Calling) procedures, INMARSAT and Iridium satellite systems, NAVTEX, EPIRBs, SARTs, VHF/MF/HF radiotelephony, distress and safety communications, radio logs, ITU Radio Regulations, and SOLAS Chapter IV requirements. Maintainer candidates also study antenna theory, power supplies, and electronic fault-finding.

Who is eligible to take the GMDSS exam?

Any applicant at least 14 years old who can receive and transmit spoken messages in English may apply. No prior maritime service is required to sit the exam, but the FCC license itself is intended for radio operators aboard SOLAS-compliant vessels of 300 gross tons or more operating beyond Sea Area A1.

How do I register for the FCC GMDSS exam?

Candidates register directly through an FCC-approved COLEM such as the National Radio Examiners, Elkins Marine Training, or Sea School. You must first obtain an FCC Registration Number (FRN) through the CORES system, then schedule and pay the COLEM's exam fee, which typically ranges from $50 to $175 per element.

What are the best tips for preparing for the GMDSS exam?

Study the complete FCC Element 7 question pool published on the FCC website, since all exam questions are drawn verbatim from it. Focus on DSC call procedures, INMARSAT-C message priorities, and distress alert cancellation. Practice with simulator software, review SOLAS Chapter IV, and take timed practice tests to build recall speed.
