GROL Exam Prep: FCC Elements

Pay once. Works offline. No subscription, no account, no ads, no tracking. GROL Prep is study software for the FCC commercial radio operator examinations — the General Radiotelephone Operator License that avionics and marine electronics technicians need, the GMDSS operator and maintainer licences, the Ship Radar Endorsement and the Marine Radio Operator Permit. It contains every question in the FCC's published question pools, reproduced exactly, with every figure. THE POOLS • Element 1 — Basic Radio Law and Operating Practice (MROP): 144 questions. Free forever. • Element 3 — General Radiotelephone (GROL): 600 questions in 100 key topics, with the 17 figures. • Element 8 — Ship Radar Techniques: 300 questions, with the 12 figures. • Element 7 — GMDSS Radio Operating Practices: 600 questions. • Element 7R — Restricted GMDSS: 300 questions. • Element 9 — GMDSS Radio Maintenance: 300 questions. • Element 6 — Advanced Radiotelegraph: 615 questions. The approval date of every pool is shown on its page and under Settings, with the FCC link and the SHA-256 of the source document. STUDY THE WAY THE EXAM IS BUILT • Study by element or by key topic. Answer, see the right answer at once, move on. • Spaced repetition: what you miss comes back tomorrow; what you know comes back later. A Due tab collects it. • Flashcards for every pool. • Practice exams that mirror the real paper: the real number of questions, one drawn from each key topic exactly as the examiners do, the real passing score, a timer, and no feedback until the end — then a review of every missed question with your answer beside the right one. • Readiness per element: a straight answer to "am I ready to book the exam?", from what you have learned, your recent practice exams and your retention. • Progress: streak, daily goal, a week at a glance, mastery by element and topic. Export it all as JSON or CSV. ONE PRICE Element 1 is complete and free forever — it is public domain, and it would be wrong to charge for it. One purchase unlocks every other element, for good, on every device signed into your Google account. Nothing here is a subscription and there is nothing further to buy. PRIVATE BY CONSTRUCTION No server, no account, no network connection except Google Play's own when you buy or restore. Everything you do stays on your device. The question pools are works of the United States Government and are not subject to copyright (source: https://www.fcc.gov/wireless/bureau-divisions/mobility-division/commercial-radio-operator-license-program/examinations). Most date from 2009 to 2021; they are the pools currently in force with the FCC's Commercial Operator License Examination Managers — confirm with your COLEM before you sit.
