Stop forgetting what you learned last month

Reviewing at expanding intervals is the most reliably demonstrated way to keep knowledge for the long term — and almost nobody does it deliberately.

This two-page cheat sheet gives you a paper-friendly interval schedule, rules for writing cards that work, and a settings guide if you use an app.

What is inside

The interval ladder — 1 day → 3 → 7 → 14 → 30 → 90, and when to reset
Card-writing rules — one fact per card, cue on the front, no yes/no
Paper system — a five-box method that needs no software
App settings guide — sensible defaults for daily new-card limits and review caps
What not to put in spaced repetition — skills that need practice, not recall

Who this is for: anyone studying material they need to remember for months or years: languages, medicine, law, certifications, or a field they are entering.
