You study, then forget
Re-reading notes feels productive but doesn’t create lasting memory. Passive review is almost useless without retrieval practice.
Review sessions pile up
Without a schedule, you add cards faster than you review them. Box 1 overflows, the habit breaks, and the whole system collapses.
Apps track streaks, not memory
Flashcard apps gamify your reviews but obscure how your memory actually works. The algorithm decides; you just click. There’s no understanding of the system.
How the Leitner System Works
Four steps. Works with index cards, sticky notes, or any paper. No app needed.
Write one fact per card
Front: the question. Back: a short answer (1–5 words). One concept only — no lists, no paragraphs.
Put new cards in Box 1
Every new card starts in Box 1, regardless of how well you think you know it. Box 1 is reviewed every single day.
Review daily — move cards forward or back
Correct answer: move the card to the next box (longer interval). Wrong answer: back to Box 1. Even a card from Box 5 goes back if you miss it.
Cards that reach the last box are learned
Once a card survives to Box 5 (or whichever is your last box), you’ve reviewed it enough times at spaced intervals to consider it learned. Retire it or move it to an archive box.
