Why timing matters
Memory fades on a curve, and the best moment to review something is right around when you'd otherwise forget it. Spacing reviews out — a day later, then a few days, then a week — resets that curve with less and less effort each time.
Spacing versus cramming
Cramming works for tomorrow morning and evaporates by next week. Spaced reviews take the same total minutes and hold for months. It feels harder in the moment (you've started to forget), and that difficulty is exactly why it works.
Let the review loop carry it
You don't have to schedule anything by hand — the Learn loop tracks every quiz question and flashcard you review and resurfaces each one when it's due.
