Unmanned Aircraft General – Small (UAG) knowledge test
The Part 107 test — what's actually on it.
60 questions, 120 minutes, 70% to pass. Below is what the FAA publishes about the shape of it, what the score report really hands you, and a 10-question sampler you can take right now.
Under 14 CFR part 107, what is the maximum weight of a small unmanned aircraft on takeoff?
About this sampler. It takes 2 questions from each of the five areas — an even spread, deliberately not the FAA's weighting. Ten questions cannot hold all five published bands at once, and rounding until it looks close would be exactly the sort of quiet inaccuracy this site exists to avoid. The weighting is real on the full-length mock.
What is on it, and in what proportion
Appendix 1 of the Airman Certification Standards gives each area of operation a percentage band. This is published, not inferred — and it is the single most useful thing to know before you start studying, because the areas are not equal and most candidates guess wrong about which one is biggest.
The full-length mock deals exactly those numbers — 12 · 12 · 8 · 5 · 23 — which is 38.3% operations. If a deal ever fell outside its published band the build would fail rather than ship a test weighted differently from the one you are sitting.
What the report gives you back
The real test is scored as a percentage of 60 questions and 70% passes, which is 42 marks. The score here is computed the same way. What the real test also gives you, and what this practice test reproduces, is the list of ACS codes for the elements you answered incorrectly — that list, and not the score, is what tells you where to go next.

Three things most Part 107 material still gets wrong
The study guide the FAA still links from its own study-materials page, FAA-G-8082-22, is dated August 2016. Part 107 was amended in January 2021, effective that April. The guide predates the amendment, and a great deal of the free material in this category was written from it — which is why you will still read all three of these:
✗ That flying at night needs a waiver.
It does not, and has not since 21 April 2021. Night operations are permitted with anti-collision lighting visible for 3 statute miles and the updated training.
14 CFR § 107.29, as amended by Amendment 107-8
✗ That you may not fly over people.
Operations over human beings are permitted under four categories, each with its own conditions, in subpart D.
14 CFR part 107 subpart D
✗ That Remote ID does not exist.
It is its own part of the regulation, and it is on the test.
14 CFR part 89
None of this makes the 2016 guide useless — weather, airspace, loading, physiology and radio did not change, and it is a good book on those. It is not a source for a rule. What changed in 2021
There is no two-year retest
The recurrent knowledge test was removed in 2021. Currency is kept with a free online course — ALC-677 for any part 107 remote pilot certificate holder, and ALC-515 for a part 107 holder who also holds a part 61 certificate with a current flight review — taken every
24 calendar months. There is nothing to schedule and nothing to pay.
Ten questions is a taste. Sixty is the test.
The full-length mock runs 120 minutes on the clock, deals at the FAA's published weighting, scores at 70% and hands back ACS codes — the same way the real one does.
Take the full-length mockFrequently asked
- What is the Part 107 test?
- Officially the Unmanned Aircraft General – Small (UAG) knowledge test. It is the knowledge test you pass to get a Remote Pilot Certificate with a small UAS rating — the certificate you need to fly a small drone for work rather than for fun. It is 60 multiple-choice questions in 120 minutes, and 70% passes.
- How hard is the Part 107 test?
- The published facts are these: 60 questions, 120 minutes — 2 minutes each — three options per question with one correct response, and 42 correct out of 60 to pass. This site does not quote a pass rate, because the FAA does not publish one and a number invented for a landing page is worth nothing to someone deciding how long to study.
- What is actually on the Part 107 test?
- Five areas of operation, and the FAA publishes what each is worth as a percentage band. The largest by a distance is Operations at 35–45% — more than a third of the test — which surprises candidates who spent their study time on the regulations.
- Do I get told which questions I got wrong?
- No, and this is the part almost nobody explains beforehand. A real Airman Knowledge Test Report gives you a score and then a list of ACS codes — one code for each knowledge element you were found deficient in. It does not reprint the questions. Learning to read that list is the difference between knowing you failed and knowing what to study.
- Do I have to retake the test every two years?
- No — and this is the single most repeated wrong answer in this category. The recurrent knowledge TEST was removed in 2021. Currency is now kept with a free online course (ALC-677 or ALC-515, depending on what else you hold), and there is nothing to pay and nothing to schedule.
- Is this practice free?
- Yes — all 293 questions, every explanation and every full-length mock, with no account and no card.
