If you Google "Part 107 practice test" you'll get a pile of results. Some are genuinely useful. A lot of them are just trivia quizzes dressed up to look like test prep. Here's how to tell the difference before you waste a week studying with the wrong one.
The Questions Need Explanations
This is the big one. A practice test that just tells you "correct" or "incorrect" isn't actually teaching you anything. The real value of a practice question is understanding why the right answer is right and why the wrong ones are wrong.
If you get a METAR question wrong and the app just moves on, you'll get the same question wrong again on the real test. If it explains the logic behind the answer, now you actually know how to decode that section of a METAR. That's the difference between memorizing and learning.
It Has to Cover the Stuff That's Actually on the Test
The FAA publishes the exact topic areas that the Part 107 exam pulls from. A good practice test covers all of them: airspace classification, weather interpretation, sectional charts, regulations, radio comms, loading and performance, and emergency procedures.
Watch out for practice tests that are heavy on regulation questions and light on everything else. Regulations are the easy part. If you're not getting weather and chart questions in your practice, you're not actually prepared.
It Should Track Where You're Weak
Doing the same 60-question shuffled test over and over isn't great prep. What you actually want is something that notices you keep missing airspace questions and pushes more of those at you. That's how you fix weak spots before test day instead of just getting comfortable with the stuff you already know.
The Questions Should Feel Like the Real Test
The actual Part 107 exam is multiple choice with four options, written in FAA language. Some practice tests use simplified wording that makes questions easier than they really are. That's a problem — you want to walk into the test center and have the questions feel familiar, not harder than anything you practiced on.
If your practice questions feel weirdly easy, that's a red flag.
What About Free vs. Paid?
Free practice tests can be totally fine if they hit the criteria above. The FAA itself has some sample questions worth looking at just to get a feel for the format and difficulty level straight from the source. Use those early on to calibrate.
Whether you pay for anything beyond that comes down to how you learn. If you need structure and tracking, a dedicated app is worth a few bucks. If you're disciplined and just need questions to drill, free resources can get you there.
