- Element 4 has 50 questions pulled one-per-group from the official pool; you need 37 correct to pass.
- E7 (Practical Circuits, 8 questions) and E9 (Antennas and Transmission Lines, 8 questions) carry the most weight - study them first.
- The current pool runs July 1, 2024-June 30, 2028 and excludes withdrawn questions E2A13, E4D05, E6D07, and E9E10.
- An ARRL VEC session costs $15 for adults ($5 under 18), and a class-only FCC upgrade application is $0.
What Element 4 Actually Tests
The Amateur Extra Class license is issued by the Federal Communications Commission, and the written test that stands between a General licensee and Extra privileges is officially called Element 4. This is the exam most people mean when they say "the Extra exam," and it's the one this guide is built around. There is no Morse code requirement anywhere in the current licensing structure, so every ounce of preparation should go toward the written material.
Element 4 consists of 50 multiple-choice questions drawn from a public question pool, and a passing score requires 37 correct answers. That's a fixed, published threshold - not a scaled or curved score - which makes it possible to prepare with real precision instead of guessing at a moving target. If you want the exact arithmetic behind that threshold, see the FCC-AMATEUR-EXTRA Passing Score 2026 guide.
Full qualification for the Amateur Extra license requires passing (or holding accepted credit for) Elements 2, 3, and 4. In practice, if you already hold a General class license, you've satisfied Elements 2 and 3, so your test session is almost always Element 4 alone. Volunteer Examiner teams, operating under a Volunteer Examiner Coordinator (VEC), administer the session either in person or through a supervised remote sitting.
The 2024-2028 Question Pool and Withdrawn Questions
Every Element 4 exam is built from the public question pool covering July 1, 2024 through June 30, 2028. That pool includes 10 reference diagrams that questions may draw on, so you can't treat this as a purely text-based exam - some questions require reading a schematic or antenna pattern correctly.
Four questions have been formally withdrawn from the current pool and will not appear on any exam built from it: E2A13, E4D05, E6D07, and E9E10. If a practice resource still includes these, it's using an outdated pool. When building or taking mock exams, insist on materials that reflect the current pool and skip withdrawn items - otherwise you're wasting study time on content that can't help your score.
Real VE-administered exams are constructed with one question drawn from each question group inside the pool. That means your practice tests should follow the same construction logic rather than randomly sampling - a randomly sampled mock exam can accidentally over-represent easy groups and under-represent hard ones, giving you false confidence.
Key Takeaway
When choosing practice materials, prioritize tools that explain why an answer is correct and track your progress by question group - not tools that simply gate access to the pool, since the pool itself is public.
Subelement Weights: Where the Questions Actually Come From
The Element 4 pool is organized into ten subelements, each corresponding to one of the ten exam domains. The official allocation of questions per subelement is fixed, and knowing it lets you allocate study time proportionally instead of spreading effort evenly across topics that don't carry equal weight.
| Domain | Subelement | Questions on Exam |
|---|---|---|
| Commission Rules | E1 | 6 |
| Operating Procedures | E2 | 5 |
| Radio Wave Propagation | E3 | 3 |
| Amateur Practices | E4 | 5 |
| Electrical Principles | E5 | 4 |
| Circuit Components | E6 | 6 |
| Practical Circuits | E7 | 8 |
| Signals and Emissions | E8 | 4 |
| Antennas and Transmission Lines | E9 | 8 |
| Safety | E0 | 1 |
Practical Circuits (E7) and Antennas and Transmission Lines (E9) are the two largest subelements, each contributing 8 of the 50 questions. Together they account for nearly a third of the exam, so weak spots in either domain have an outsized effect on your score. For a full walk-through of what each of the ten domains covers conceptually, see the FCC-AMATEUR-EXTRA Exam Domains 2026 guide.
Practical Circuits (E7)
Covers amplifier configurations, filter types, digital logic basics, and power supply circuits - the kind of applied electronics that shows up as schematic-reading questions.
- Know common amplifier classes and their tradeoffs
- Be able to identify filter types from a described response
- Recognize basic digital logic gate behavior
Antennas and Transmission Lines (E9)
Covers antenna types, feedline characteristics, standing wave ratio, and matching - often the most calculation-heavy domain on the exam.
- Understand how antenna gain and radiation pattern relate
- Be comfortable with basic SWR and impedance-matching problems
- Know characteristics of common feedline types
The remaining subelements are smaller individually, but Commission Rules (E1) and Circuit Components (E6) each still supply 6 questions - enough that skipping them is not a viable shortcut. Safety (E0) contributes only 1 question, which makes it low-priority relative to time invested, though it should never be skipped entirely since it's still one guaranteed point.
Registration, Fees, and What to Bring
Cost mechanics for Amateur Extra upgrades are simpler than people expect, but the pieces are easy to mix up. The ARRL VEC's 2026 session fee is $15 for adults, or $5 for candidates under 18, and that fee covers one attempt at each element you sit for in that session. If you fail Element 4 and need to retake it, that requires paying the examination fee again for the retest.
Separately, the FCC itself charges no application fee for a class-only upgrade - going from General to Extra costs $0 at the FCC level. The FCC's $35 fee applies to new-license and renewal applications, not to upgrading your class on an existing license. Put together, an adult General-to-Extra upgrade through ARRL VEC ordinarily costs $15 total before you spend anything on study materials. For a complete line-item breakdown, see the FCC-AMATEUR-EXTRA Certification Cost 2026 guide.
Exams are closed-book. If you plan to use a calculator for any Ohm's Law or antenna-length calculations, its memory and any stored formulas must be cleared before the session, and a phone cannot be substituted as a calculator. Bring a simple, memory-clearable calculator rather than risk being told to set your device aside.
A Domain-Ordered Study Timeline
Generic study techniques like spaced repetition work fine, but they only help if you're spacing repetition across the right material in the right order. Because E7 and E9 together supply 16 of the 50 questions, they deserve the earliest and heaviest attention, while E0's single question can wait until the end.
Antennas and Transmission Lines (E9) + Circuit Components (E6)
- Work through antenna types, feedline loss, and SWR problems
- Review component behavior: resistors, capacitors, inductors, semiconductors
Practical Circuits (E7) + Electrical Principles (E5)
- Study amplifier, filter, and oscillator circuit questions
- Reinforce the math underneath E7 with E5's electrical formulas
Commission Rules (E1) + Operating Procedures (E2) + Amateur Practices (E4)
- Memorize rule-based questions on privileges, frequency limits, and station identification
- Cover operating procedure and practices scenarios likely to appear as short recall items
Radio Wave Propagation (E3) + Signals and Emissions (E8) + Safety (E0) + Full Review
- Finish the smaller subelements
- Run full 50-question mock exams built one question per group, including the 10 diagrams
- Confirm no withdrawn questions (E2A13, E4D05, E6D07, E9E10) are appearing in your practice set
If you want a condensed, single-page version of the highest-yield facts to review the night before your session, the FCC-AMATEUR-EXTRA Cheat Sheet 2026 is built for exactly that. And if you're still deciding how much runway to give yourself, the How Hard Is the FCC-AMATEUR-EXTRA Exam guide breaks down where most first-time candidates lose points.
Exam Day Mechanics and Remote Sessions
Volunteer Examiner teams run sessions under VEC oversight either in person at a local testing location or through a supervised remote session using video and screen-sharing tools. Both formats use the same pool and the same 37-of-50 passing threshold - remote sessions do not use a different or easier question set.
Before scheduling, confirm your session date, format, and any pre-session paperwork requirements directly with the VE team, since local scheduling windows vary by team and location. For a broader look at how testing calendars and deadlines typically work across the year, see the FCC-AMATEUR-EXTRA Exam Dates 2026 guide.
Key Takeaway
Whether you test in person or remotely, the exam construction rule is identical: one question per group from the current pool, 50 questions total, 37 needed to pass.
After You Pass: Credit, CSCE, and Renewal
Passing Element 4 with existing credit for Elements 2 and 3 completes qualification for the Amateur Extra license. The VE team issues a CSCE documenting your result, and if for any reason your upgrade isn't processed immediately, that CSCE preserves your Element 4 credit for 365 days - plenty of time to complete paperwork or resolve an FRN issue without retesting.
Amateur licenses normally run for a 10-year term. Renewal opens 90 days before expiration, and there's a 2-year grace period after expiration during which you can still file to renew - though that grace period itself grants no operating authority, so don't transmit while lapsed. Ordinary renewal requires no repeat examination and no continuing-education credits, which distinguishes amateur licensing from many commercial certifications that demand periodic recertification. For the full mechanics of eligibility and what counts as accepted credit, see the FCC-AMATEUR-EXTRA Requirements 2026 guide.
If you're weighing whether the upgrade is worth the study time given that it doesn't expire on a testing cycle, the Is the FCC-AMATEUR-EXTRA Certification Worth It guide and the FCC-AMATEUR-EXTRA Pass Rate 2026 guide lay out the practical tradeoffs in more depth.
Start your review with a baseline practice run at the main practice test hub to see which of the ten domains needs the most attention before you commit to a fixed study calendar.
