Quiz
Random questions across 505 items. Short answers, predict-and-reveal, line-by-line code walks — interleaved on purpose, because recall sticks better when topics mix instead of blocking.
Spaced-repetition active — items you've missed surface more often; mastered ones step back to make room for fresher material.
