LEVEL 3: Extra Class License, Exam Requirement: 50-question Extra written exam (Element 4).
General licensees may upgrade to Extra Class by passing a 50-question multiple-choice examination. No Morse code test is required. In addition to some of the more obscure regulations, the test covers specialized operating practices, advanced electronics theory and radio equipment design. Non-licensed individuals must pass Element 2, Element 3 and Element 4 written exams to earn an Extra License. The FCC grants exam element 3 credit to individuals that previously held certain older types of licenses. Find valid forms of Examination Element Credit.
Extra Class Question
Only correct answers! I have found that if you read only the question and correct answer, it is the easiest way to pass the exam. No lengthy books, no flash cards, and no classes, just read through the question and correct answer one after another and go take the exam.
