9. ASSESSMENTS & QUIZZES

(Quizzes test retention, not understanding. If you can pass these without looking up answers, great - you remember the material. If not, that's fine too. What matters is whether you can build working systems, not whether you memorized which embedding model is cheaper. Use these to identify gaps, then go back and reread those sections.)
