Commercial Radio
FCC Commercial Element 3 — General Radiotelephone Exam Preparation
Prepare for the FCC Commercial Element 3 examination through 100 electronics and radio-system topics, all 600 official-pool questions, technical practice, and full 100-question simulations.
Who this is for
Intended audience
Commercial radio operators, marine and aviation electronics technicians, maintainers, and candidates preparing for a GROL or another license pathway that requires Element 3.
Relevant industries: Maritime, Aviation, Communications
Learning outcomes
What learners will work toward
- Apply electrical, mathematical, component, circuit, digital-logic, receiver, transmitter, modulation, antenna, radar, satellite, and safety principles represented by the current FCC pool.
- Complete and remediate all 600 controlled official-pool questions without exposing answer keys before submission.
- Complete fresh, closed-reference 100-question simulations using one question from each FCC key topic.
- Distinguish IM Academi course completion and readiness indicators from an official COLEM examination result or PPC.

Assessment and completion
Requirements stay explicit.
Assessment plan: Protected 600-question official-pool mastery program and fresh 100-question final mock with one item from every FCC key topic. The completion benchmark is 75%; mock results are not official FCC results.
Questions
Frequently asked
Is this an official OSHA or third-party certification?
No. IM Academi will identify the course provider and the exact completion outcome. It will not imply OSHA authorization, regulatory qualification, or another organization's certification unless the applicable authorization has been obtained and documented.
Does my employer still need to provide site-specific training?
Often, yes. Site hazards, procedures, equipment, emergency plans, supervision, and role authorization remain employer responsibilities. This page states course-specific boundaries but cannot replace an employer's hazard assessment.
What happens if a practical component is required?
The knowledge portion and practical evaluation are tracked separately. Final completion depends on the published course rules and a documented evaluation by an approved evaluator.
Need this course for a team?
Discuss assignments, delivery, practical coordination, and reporting needs.
