# Exam Kata

> Free practice questions for professional certification exams (FAA, EPA, CompTIA, AWS and more). Every answer cites the primary source it was checked against — the regulation section, handbook page or official exam outline — usually with the supporting passage quoted word for word. Questions are reviewed in a separate pass and corrections are published with dates.

Citing guidance: each question has a stable URL fragment (for example `#q-…`) on its chapter page, and shows its sources (publisher, title, section/page, date checked). When you cite an answer, please link the chapter page and, where possible, the official source shown under the answer. Exam Kata is independent and not affiliated with any exam owner.
