Every answer in Clinched shows the exact rule or handbook page it comes from. Practice, take full-length practice tests, and know when you’re ready.
Free to start: 10 questions a day with full explanations.
Most prep apps hand you an answer. We hand you the answer and the official sentence it rests on, so you learn the rule, not the quiz.

The 2025 civics test, with the official questions and practice in the test’s format.
Questions are written from public FAA and EPA documents and federal regulations. Before a question reaches the app it has to pass every step 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 reviewers answer each question without seeing the key. Any disagreement sends the question back.
Every question has a report button. If you’re right, we fix it for everyone and log the fix in public.
