Exam Eligibility
Before you can register to take the Ham Radio Extra Class exam, you’ll need to take and pass the Technician Class and General Class exams. Once those are under your belt, you’ll be set to take the Extra Class exam!
What’s on the Exam?
The Extra Class exam contains 50 multiple-choice questions, which are grouped into 10 sections. The questions in each section are pulled from a question pool, so each administration of the test contains a different set of questions.
