Free Part 107 test diagnostic
The diagnostic draws 20 original questions in proportion to the Federal Aviation Administration (FAA)'s published content weights, so a topic worth 25% of the exam gets about 25% of the questions. Your result is a blueprint-weighted readiness score (0–100) with a band per topic. It is not a pass probability: nobody has outcome data to calibrate one, so we do not pretend to.
20 questions, drawn in proportion to the official Part 107 test blueprint. You will see the rationale after every answer. Nothing to sign up for; progress stays in this browser.
How the score works
Each topic's mastery is a recency- and difficulty-weighted correctness rate, shrunk toward "unknown" when you have answered fewer than three questions in it. Overall readiness is the sum of blueprint weight × topic mastery. Bands: Strong ≥ 80%, Developing 60–79%, Needs focused review below 60%. Full method on the methodology page.
