Questions are written from public FAA and EPA documents and federal regulations. Before a question reaches the app, it has to pass the first three steps below.
Each question is drafted from the regulation, handbook or chart it tests, never from memory.
We check every quote against the official document automatically. If it doesn’t match exactly, the question doesn’t ship.
Separate AI models answer each question without seeing our key. Any disagreement is re-checked against the source, and the question is kept, corrected or removed.
Every question has a report button. If you’re right, we fix it for everyone and log the fix in the app.
