Spaced repetition in 1885: Forgetting curve

This atlas ranks it near the top for evidence, exam fit and long retention, and middling for first-week speed — early hours go to card design. Use it as a calendar for facts you must still name in six months — not as a substitute for a blank-page problem. Spaced repetition: What is this, in one honest paragraph?

A schedule that asks for a retrieval just before you would have forgotten, then lengthens the gap after a success. Spaced repetition: What does the evidence actually say? Ebbinghaus showed savings on relearning; Cepeda et al. found expanding gaps beat cramming for delayed tests; Leitner and SuperMemo turned the idea into boxes and algorithms.

Spaced repetition: How does it help a high-stakes exam? It fits listing, definition and formula items that return on later papers. It does not grade a proof you have never written. Spaced repetition: How fast is a first honest gain? A first honest lift is often two to three weeks of daily reviews, not the first night of card-making.
