By mark overhuel, from the App StoreDescription by mark overhuel Written by the developer, not by AppBrain. Click to read.
Prepare for the FCC General Radiotelephone Operator License (GROL) exam with a study app built around the official Element 1 and Element 3 question pools — 743 real exam questions from the FCC question pools.
THREE WAYS TO PRACTICE
• Quick 20 — a fast, randomized 20-question session for a short study break
• Simulated Exam — draws one random question from each exam topic, exactly the way the real FCC test is assembled, so you get a realistic sense of what test day feels like
• Full Pool — every question in the element, for thorough review
KNOW WHAT TO STUDY NEXT
Statistics are tracked down to the subsection level, not just an overall score, so you can see precisely which topics are still weak instead of re-studying material you've already mastered.
LEARN AS YOU GO
Choose to be told immediately when you miss a question, with a plain-language explanation of why the correct answer is right — or go straight through a full session and review everything at the end. Every question shows which exam subsection it belongs to, and the ~21 questions that reference a circuit diagram show the real figure from the official pool, not just a text description.
SEARCH EVERY QUESTION
Browse the complete question pool with search, read every explanation at your own pace, and study outside of quiz mode whenever you want.
GROL Trainer is an independent study tool built from the FCC's publicly available Element 1 and Element 3 question pools. It is not affiliated with or endorsed by the FCC.
