The science of memory
Why spaced repetition works
The forgetting curve
Psychologist Ebbinghaus showed that we forget most new information within 24 hours unless we review it. Each review resets the forgetting curve — making the memory stronger and the curve much shallower next time.
Space it out, not cram
Studying the same material across 5 sessions over 30 days produces 3-4x better long-term retention than cramming the same material into a single session. The spacing effect is one of the most replicated findings in cognitive psychology.
Memory hints accelerate learning
Mnemonics, analogies, and memory hints reduce the mental effort required to retrieve information. When you attach a memorable hook to a fact, retrieval becomes automatic rather than effortful.

Frequently Asked Questions
What is spaced repetition?
Spaced repetition is a study method where you review material at increasing intervals. Instead of re-reading everything daily, you review it on Day 1, Day 3, Day 7, Day 14, and Day 30 — each review strengthening the memory and extending how long before you need to review again.
What topics work best for this?
Any factual content you need to memorise long-term: vocabulary, historical dates, scientific formulas, legal principles, medical terminology, language learning, and more. Less effective for procedural skills that require practice.
How do I use the schedule?
Start on Day 1 with the first review session as described. Set reminders for Day 3, 7, 14, and 30 from today. On each review day, go through all the flashcard-style facts and try to recall them without looking at the hint first.
