Practice the decisions behind AI work.

Independent questions

Our question bank contains original scenarios, including AI-assisted authoring, based on public technical documentation and exam topic guides. Explanations link to source material so you can check the reasoning. The bank is growing and does not cover every exam objective. It does not contain live vendor exam questions.

What a score means

Your accuracy is correct answers divided by all questions in the attempt. A skipped question counts as incorrect. Topic results show performance on the questions in that set. Our 80% goal is a study target; it is not a prediction that you will pass an official exam.

Earlier versions displayed an internal 100 to 1000 practice score. That number was not a vendor-calibrated scaled score. Current results emphasize percentage correct and the actual question count.

Interview practice

Skills labs provide untimed scenario practice for applied AI decisions. Multiple-choice feedback checks the selected answer; it does not evaluate spoken delivery, code quality, or how you would perform in a live interview.

Practice badges

A shared result records an unproctored practice attempt on AI CertArena. It does not verify identity, grant a professional qualification, or replace a vendor certification. Share it as study progress or add the result link to your LinkedIn Featured section.

Official sources

Each study guide links to the relevant provider. AI CertArena is not affiliated with or endorsed by Anthropic, OpenAI, AWS, Microsoft, Google, Databricks, or Pearson VUE. Their names identify the products and exams being discussed.
