GroundSchool Prep

Walk into your FAA knowledge test already knowing you'll pass. GroundSchool Prep builds practice exams for three FAA knowledge tests: Private Pilot, Instrument Rating, and Commercial Pilot (Single-Engine Land). Over 3,000 questions, written from public FAA source material — the Pilot's Handbook of Aeronautical Knowledge, the Airplane Flying Handbook, the Aeronautical Information Manual, and 14 CFR. EVERY ANSWER IS EXPLAINED Each question carries a written explanation and a source reference, so you learn why the right answer is right instead of memorizing which letter it was. Answer choices are reordered on every attempt, so you can't pass by remembering positions. BUILD THE EXAM YOU NEED Pick the ACS knowledge areas you want to drill and how many questions you want. Practice exams give you feedback as you go, and you can review any past exam question by question — including the figures and sectional-chart excerpts the real test uses. SEE WHERE YOU ACTUALLY STAND Your progress is broken down by ACS knowledge area, so it's obvious which subjects need another pass and which are already solid. Unfinished exams are saved, so you can stop mid-exam and pick it up later. ENDORSEMENT EXAMS When you're ready, sit a full 100-question simulated knowledge test. Three consecutive endorsement exams at 80% or better unlock a printable report you can hand to your instructor for the sign-off you need before the real test. Endorsement exams draw adaptively — the more you miss in an area, the more of that area you get, with every ACS area still represented. ONE PURCHASE PER CERTIFICATE Each certificate unlocks separately for 60 days. It's a one-time purchase, not a subscription: nothing auto-renews and there's nothing to cancel. Add another certificate whenever you want and the days stack onto what you already have. NO ADS, NO TRACKING No advertising, no analytics, no third-party trackers, and no data sold to anyone. You can delete your account, and everything in it, from inside the app. An internet connection is required — questions are served from a single shared bank so corrections and additions reach you immediately, without waiting for an app update.
