About this app

Study for the FCC General Radiotelephone Operator License (GROL) with the complete Element 1 and Element 3 commercial radio operator question pools. Every question is the real, word-for-word FCC pool question with the official answer, plus a clear explanation written in plain English.

The GROL is the commercial radio operator license used for maintaining and repairing transmitters in the maritime and aviation radio services. It is not the amateur (ham) radio license. To earn it you pass two written elements: Element 1 (Basic Radio Law and Operating Practice), 24 questions with 18 to pass, and Element 3 (General Radiotelephone), 100 questions with 75 to pass. Both are 75 percent, and this app covers all 744 questions in both official pools.

ABOUT THE QUESTIONS
The FCC publishes the commercial operator question pools, and because they are United States federal government works they are in the public domain. We reproduce the real questions with the official answer key and write our own explanations. Before release, a second independent AI model confirms each explanation supports the keyed answer.
