The FCC GROL exam is not one test to cram for, it is two separately scored elements with different content and a shared 75% bar. This plan works through both in the order they are worth studying, then covers how the actual sitting gets booked.
What score do you actually need?
Element 1 (Basic Radio Law and Operating Practice) has 24 questions and needs 18 correct. Element 3 (General Radiotelephone) has 100 questions and needs 75 correct. Both land at 75%, and that mark applies to each element on its own: a high score on one does not offset a weak score on the other. Study and practice each element to its own pass standard, not to a combined average.
Element 1: four categories, no shortcuts
Element 1 splits evenly across four categories: rules and regulations, communications procedures, equipment operations, and other equipment. Each carries the same weight toward the 24 questions, so there is no single area to over-index on. Work through all four to a comparable depth before moving to Element 3.
Element 3: study the heaviest topics first
Element 3 is the larger, more technical element, spread across 17 subelements that are not weighted equally. Three topics carry the most questions, 10 each out of 100:
- Electrical math: Ohm’s law and the calculations behind voltage, current, resistance and power.
- Components: resistors, capacitors, inductors, semiconductors and other parts.
- Receivers: superheterodyne receivers, selectivity, sensitivity and demodulation.
Just behind those, at 8 questions each: installation and maintenance, digital logic, and electrical principles. Together these six subelements make up more than half of Element 3, so get them solid before spreading study time thinner across the rest.
Element 3: the mid- and lower-weight topics
The remaining subelements carry fewer questions but still add up:
- 6 questions each: transmitters, aircraft radio.
- 5 questions each: antennas and feed lines, marine radio, RADAR.
- 4 questions each: satellite systems, circuits.
- 3 questions each: modulation, power sources, communications technology.
- 2 questions: safety, the lightest single subelement.
At a 75% pass mark, a category you write off entirely can still cost you the element, so plan time for all of them, just less for the lighter ones.
Why drilling the real questions works here
Most exam prep asks you to practice lookalike questions because the real question bank is copyrighted and hidden. The GROL is unusual: the Element 1 and Element 3 pools are works of the U.S. federal government and sit in the public domain under 17 U.S.C. 105, so the FCC’s actual pool questions and official answers are published outright. Practicing the real pool wording, rather than a paraphrase, is about as direct as exam prep gets: the sitting draws from the same pool you are studying.
Practice at the real pass standard
Run full timed mocks that score Element 1 and Element 3 separately, each against its own 75% mark, rather than one blended number. Keep sitting mocks and reviewing whichever element is behind until both consistently clear 75% on their own, not just on average.
Booking the actual sitting
The FCC does not administer the GROL exam itself. You sit it through an FCC-authorized Commercial Operator License Examination Manager (COLEM), and each COLEM sets its own fee and scheduling, so check those details directly with the COLEM you plan to use. Once both elements are passed, the GROL is issued as a lifetime license with no renewal exam, so the study effort here is a one-time push rather than something to repeat.
This app draws its practice questions directly from the FCC’s public Element 1 and Element 3 pools, weighted to match the real subelement breakdown above, so a mock here reflects the actual exam’s shape. It is an independent study aid and is not affiliated with, endorsed by, or representing the Federal Communications Commission.
