Mandatory checkpoint quiz for Chapter 8 — AI Layer. 5 random questions drawn from a 15-question bank. Pass to unlock Chapter 9.
Chapter 8 Checkpoint
You've finished the AI Layer chapter. Make sure the practical patterns stuck — RAG, tool calling, agents, costs, observability.
There are 15 questions in the bank — each visit picks 5 at random, so retaking gives you different ones. If you miss one, the result card tells you exactly which page section to revisit, and the link highlights the paragraph for you.
You must pass (≥ 67%) to unlock the Next button and Chapter 9 in the sidebar.
