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 — a protocol you can run this week. A working protocol for atomic cards is capture, schedule, retrieve, repair, mix, audit.

Scores here are relative ranks inside this atlas, not lab grades or official cut scores.

Steps

  1. Capture

    Write cards from a public outline, one fact each, answer hidden.

    If you need a comma in the question, split the card.

  2. Schedule

    Set a daily due time and a new-card cap so the queue cannot explode.

    Cap new cards before you cap reviews.

  3. Retrieve

    Grade honestly: a peek is a fail, even if you then recognise the line.

    Recognition is not recall.

  4. Repair

    Suspend or rewrite leeches after a set number of lapses.

    A leech is usually two facts glued together.

  5. Mix

    Keep related procedures on separate cards and mix their due dates.

    Interleaving lives in the queue, not inside one card.

  6. Audit

    Once a week, mark young high-yield cards and check them against the public outline.

    If the outline moved, the deck must move.

Variants

Educational atlas — not an official syllabus, medical advice, or leaked item bank. Spaced repetition: Keep the public outline in view and treat this page as method, not a leaked key.
