How we write and check questions
Our promise is simple: every answer is backed by an official documentation page you can open and read.
Where questions come from
- We start from the official exam guide and its task statements.
- Each question is original and is written from an official documentation page (for AWS: docs.aws.amazon.com and aws.amazon.com).
- We never use exam dumps, recalled questions or leaked content, and we never ask buyers what was on their exam.
How every question is checked
- Citation check. A script fetches the cited page and confirms the quoted sentence appears on it word for word.
- Builder passes (A, B, C). The AI system that wrote the questions answers them again from separately shuffled packets without the answer key. Pass B also rates whether the cited sentence supports the answer, and a third pass (C) re-checks anything flagged. Because the same system wrote and reviewed these, we count them as self-checks, not independent review.
- Independent reviewer pass. A separate AI reviewer answers the full bank blind and flags weak citations, unclear wording, out-of-scope topics and outdated services.
- Fix or drop. Every flag is resolved: we strengthen the source, rewrite the question, or retire it and write a replacement. Changed questions go through the citation check, a builder blind check and a second independent blind check. Retired question IDs are never reused and are listed on the errata page.
- Automated rules. Domain weights within 2 percentage points, balanced answer positions, no "all of the above", no near-duplicate questions.
All reviewers are AI systems, supported by automated checks. We tell you this plainly so you can weigh it, and every answer links to its source so you can check it yourself.
