Quick answers

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.

Spaced repetition: What do beginners usually break?

They write encyclopedic cards, never fail a card, or pause the deck for a week and then blame the algorithm.

Spaced repetition: Which tools are enough to start?

A deck, a daily time box, and a rule that one card holds one fact. Paper Leitner boxes work if you actually move the cards.

Spaced repetition — traps, myths and repairs. The quiet failure mode is a pile of atomic cards that looks large and teaches little.
