Exam Kata is a question bank for certification exams where each answer is tied to the exact regulation, handbook page or official exam document that proves it — quoted word for word, checked by a separate reviewer, and corrected in public when we get something wrong.

Certifications
We add exams one chapter at a time, and only after every question in that chapter has passed source checks and a separate review. No filler questions to pad the count.
Aviation & Drones
FAA knowledge tests, built from the regulations and handbooks the FAA itself publishes.
Environment & HVAC
EPA certifications for technicians, grounded in the Code of Federal Regulations.
Our method
How a question earns its place
Most practice banks ask you to trust them. We show our working instead — on every question.
Written from the source
Each question starts from the official text: the regulation, the government handbook or the exam owner’s published objectives — never from another quiz.
Quoted word for word
The passage that proves the answer is stored with the question and machine-matched against our saved copy of the document. If the quote is not in the source, the question cannot be published.
Checked by a second reviewer
A separate review pass re-reads the whole question against the source: the answer, every wrong option, the explanation and whether the wording gives the answer away.
Corrected in public
Every question has a Report button. When a report turns out to be right, we fix it, search for the same mistake elsewhere and log the change on the corrections page.
