Work through the levels in order. Type your answer and press Check — open the worked solution if you get stuck. Answers like -6, 3/4 or 0.25 are typed exactly as shown.
Level 1 · Warm-up
1 Which activity is ACTIVE recall?
Show worked solution
Closed-book questions — retrieval is the engine; the other three are recognition-building (weak).
2 Immediately after learning something, you retain about ____; by the next day (no review) about ____.
Show worked solution
~100% → ~40% — which is why a 10-minute review tomorrow beats an extra hour today.
Level 2 · Core
3 Using flashcards where the front of the card prompts the answer is which kind of recall?
Show worked solution
Cued recall — the cue (card front) prompts retrieval. Blank-page dumps are free recall; ordered steps are serial.
4 Which review schedule best fights the forgetting curve for material learned on Monday?
Show worked solution
Spaced self-tests (Tue / Fri / next week) — each retrieval lifts the curve and slows its fall. Massed re-reading decays like a single exposure.
Level 3 · Challenge
5 Writing your OWN test questions (DIY) is powerful because…
Show worked solution
Question-writing forces examiner-level thinking — choosing what matters, designing distractors, setting the Bloom level. The writing is the studying.
6 A student scores 6/10, reads the worked solutions, nods along, and moves on. What does the retake rule say is missing?
Show worked solution
The misses stay open until re-attempted unaided — ideally the next day (spacing!). Nodding at solutions is recognition; producing them is learning.
