Certification prep often stops at notes and multiple-choice questions. Copilot Studio makes more sense once you actually build something.
So I added a free AB-620 hands-on lab to Examplar.
It covers creating an agent, writing clear instructions, testing in-scope and out-of-scope prompts, publishing it, and cleaning up afterwards. Each step includes something learners can check before moving on.
The public Preview also has 25 original practice questions. No exam dumps.
Examplar is my independent, open-source side project. The Preview and lab are free, and the page also links to optional paid packs.
