The lab guides learners through creating an agent, writing instructions, testing prompts, publishing, and cleanup, with checkpoints at each step. The public Preview also includes 25 original practice questions, with optional paid packs available.", "body_md": "Certification prep often stops at notes and multiple-choice questions. Copilot Studio makes more sense once you actually build something.\n\nSo I added a free AB-620 hands-on lab to Examplar.\n\nIt 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.\n\nThe public Preview also has 25 original practice questions. No exam dumps.\n\nExamplar is my independent, open-source side project. The Preview and lab are free, and the page also links to optional paid packs.\n\nTry the free lab: [https://examplar.app/exams/ab620/#labs-h](https://examplar.app/exams/ab620/#labs-h)\n\nBlunt feedback is welcome.
