Study strategies · Memory

Since Ebbinghaus mapped the forgetting curve in 1885, the evidence has pointed one way: distributed practice beats massed practice, reliably, across subjects and learners. Everyone knows it. Almost nobody does it. This guide is about the doing.

Why the best technique is the least used

Spaced repetition fails not because learners doubt it but because of friction. The fifth review of the same material requires sitting down, opening the book, and rereading paragraphs you already resent. The activation energy is high, the novelty is zero, and life wins.

Fix one: move reviews into occupied time

The single most effective change is to take reviews off your desk. A re-listen during a commute or a walk costs no calendar time and carries no dread. Save desk time for first passes and practice questions; let audio carry passes two through five.

Fix two: use a simple interval ladder

You don’t need software or perfect intervals — approximately right, consistently done, wins. A workable ladder for exam prep:

• Day 0: learn it (read or first listen)
• Day 1–2: first review (audio)
• Day 5–7: second review (audio + recall pauses)
• Day 14: practice questions on the topic
• Day 30: final re-listen of weak sections only

Fix three: let your error list set the schedule

Review everything and you’ll review nothing. Practice-question misses and marked audio timestamps form your error list; the ladder above applies with full force only to that list. Material you keep getting right graduates to a single day-30 touch.

What this looks like in a real week

Two new chapters at your desk, four commute re-listens, one question block, ten minutes on Sunday moving misses onto next week’s list. No app required — a notebook page per week does it.
