Distilled from the AI-103 community study guides and notes in github/ai-103, the practice-question PDFs, and the Microsoft Learn skills outline (as of April 16, 2026) into 0 distinct testable facts, organized by the five official domains. Each card gives the scenario, the answer, and the gotcha that rules out the near-miss options. Click a card to reveal it, and check it off once you know it. Progress is saved in this browser. Foundry renames things often: when a card and Microsoft Learn disagree, Learn wins.
