CertPrep is a small independent project by Karkuv. The goal is simple: give learners a clean, honest place to practise for an AWS exam without a paywall or an account.
What you get
- Full-length timed practice sets that follow the structure of the exam guide.
- A progress map, question flagging and a pause button, so practice feels like the real thing.
- A score, a breakdown by exam domain and an explanation for every question.
- Links to AWS's own official resources on each exam page, labelled free or paid.
Where the questions come from
All questions are original. They are written by the site author with the help of AI tools, based on AWS's public exam guides and documentation. We do not publish real exam questions or copied content. AI-assisted writing can still contain mistakes, so if you spot one, please tell us (see the contact page).
How it is paid for
The site is free to use and supported by advertising. Ads are always labelled and kept away from the questions and answer buttons. See the privacy policy for details on how ads and data work.
