About this site

01What the site is, in plain terms

Independent

No tie to AWS. The CWI and AWS names appear so you know which exam the site is about, nothing more.

Open to read

Every page, tag and remark here works without an account or a sign-up.

Paid for by the app

The Get the app button leads to our CWI prep app on the App Store. That's how the site pays its way.

Not a course

There's no instructor, seminar or certificate here. AWS seminars and schools fill that role, and CWI prep compared sets them side by side.

02Where the facts and tags come from

Exam rules, fees and dates come from AWS documents: the AWS CWI Examination User Guide, the information sheet for each part, AWS B5.1:2025 and the AWS CWI page. Each fact sheet names its source and the month it was checked. The current round of checks was done in October 2026.

The tags come from the question bank behind our app, sorted by clause, plus a few new items written where a concept page needed them. Every item carries a remark on each option. Code content stays at the clause level and names its edition, because D1.1:2020 and D1.1:2025 number their tables differently.

03Lines the site doesn't cross

No page carries Part B exhibit material or recalled exam items; AWS candidates sign an attestation that keeps exam content confidential. No page shows a pass rate, because AWS doesn't publish one. And nobody here is presented as a CWI or as a credentialed reviewer, because there's no name and certificate behind such a claim to show you.

04Fixing mistakes

A key you think is wrong, a fee that changed, a page that breaks on your phone: the contact page says how to report it. What the site records about you is on the privacy page. The short version: no cookies or analytics, a log entry when you tap Get the app, plus the host's routine request logs.
