Spend less time studying and more time flying! This is the COMMERCIAL PILOT version of GroundSchool, our FAA knowledge (written) test preparation featuring up-to-date questions, free updates, and illustrated explanations written by a professional team of pilot examiners and instructors.

GroundSchool is fully compatible with FAA ACS (Airman Certification Standards) and our editorial team is working to keep it so as ACS continues to evolve.

Don't be fooled by imitators! Competing apps use only the limited set of questions that the FAA publicly releases via its website - that is not enough to adequately prepare you for your test! Our GroundSchool app, on the other hand, features a much more comprehensive database (typically about 2-4 times the size of the demo FAA public one) of actual and current FAA questions that you likely can and will be asked on the actual test! This along with our detailed, professional explanations and easy to use interface are major reasons why pilots have come to trust GroundSchool.

Study actual, up-to-date FAA questions and then ACE your FAA Commercial Pilot knowledge (written) test the easy way with GroundSchool FAA Knowledge Test Preparation software by Dauntless Aviation, the trusted leader in FAA written test preparation.

Outdated database

I’ve used this company for all my written’s and even outdated written’s I had to take again, I really like the layout and in the past the explanations were amazing it helping you understand why a certain answer was correct over the other options, however in the past couple years I’ve noticed less explanations and less visuals and references and more so just a simple FAA referance highlighted from the Aim or whatever source. Anyway that alone doesn’t deter me, I understand it’s hard to keep content up to date, I just think with the competition what’s being offered now is not worth the price. If a person uses this product to study expect to get about 7 percent lower score on your actual exam then you do on all your practice ones as the database seems to be about that old consistently

Keep it fresh!

I also feel bad about writing this but their questions database is very out of date (there are still 20+ questions on NDB’s and ADF’s with a disclaimer in the explanation...these have long since been eliminated from the test..) ... they claim to be updating their content but, while the content is correct, it only distantly resembles what you see on the test.
They do explain things well &, since I understood the material, I would up with a good score on the test...there just was a lot of crap to wade thru to get to the stuff I needed to know.

The only way I prepare for tests, or let my students take them

I’ve used Dauntless apps to prepare for every FAA written test I’ve taken, and my lowest score is 90%.

Two features that are absolutely worth mentioning are the ability to share test results with an instructor, which allows a student to prepare on their own tim. An instructor can track preparation and even provide a remote sign-off (by scanning the endorsement and emailing it).

The second feature is that the app gets free updates for life. I began in aviation as a glider pilot, and used the app to pass my glider test. When I decided to fly airplanes, I updated the app and its question bank, and studied for another test at no charge. If you will be taking lots of knowledge tests, the free updates will save you a bundle.

Don’t use this app to memorize test questions. The FAA no longer publishes test questions, so no app will have a question bank to simply memorize. Go through the question bank, READ all of the excellent explanations, and you’ll be prepared for whatever the FAA puts on your test.
