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.

Out of date question bank

The syggjdndhhhebv

I feel bad writing this, but I just finished the commercial written exam today (March 8th, 2018) with a 79% score.
I studied religiously with this app, regularly updated it, and from the 100 questions on the exam I had seen only about 15-20% of these questions on the Dauntless app. The rest were all new to me.

The app is well made and the study options are good. However they’re not worth much if the question bank is outdated.

Decent App, Terrible Company

Extremely rude disrespectful "CFI's"...

Have been studying with this app along with King Courses and a few others for my Commercial Certificate.

Came across a question in Aerodynamics about combined effects of slipstream and torque effect, Dauntless gave one answer, while King, Gleim, and several CFI's gave a different answer. So I used the form Dauntless provided within their app to submit that an answer may be incorrect, kindly asked them for clarification.

The response I received from one of their CFI's was shocking. Down right rude and extremely disrespectful! Rather then what any other CFI would do explaining the answer, He pretty much flipped out on me for questioning the answer. Extremely nasty reply that how dare I question them, everyone else is WRONG and their answer is right, I'm lazy and trying to get them to do everything for me, blah blah blah.

I submitted the same question to King Schools and got a very pleasant detailed response explaining their answer. After doing some web searching on this particular question, there is actually quite a bit of debate on the answer, so not sure why they were so shocked that I would question it. Anyways the app itself isn't bad, although you shouldn't have to pay an extra $20 for the audio feature. Terrible company and customer service.

Great supplement to prepare!


I just completed my Commercial rating and it was made easier thanks to this app. I studied using the ASA books, and that was a great thorough study, but then added a few rounds of this app to prepare for the written. I got a score in the 90's with no problem. I really like the question stacks and the ability to get immediate explanations configured to display either all the time, or only when you get one wrong. It's a great package. I didn't really use the check ride prep one much, but I should before my CFI. I also used the dauntless prep for my CFI FOI test today and scored in the mid 90's as well, so you can bet I'll be using this for the FIA test as well.
