The science of learning, made practical.

Decades of research point to a few techniques that move retention: spaced repetition, active recall and deliberate practice. Here is how they work, and how to use them in MintDeck.

Active recall & retrieval practice

Memory is built by retrieving, not re-reading. Testing yourself is the mechanism that makes spaced repetition work — these guides explain the testing effect and how to use it.

Key concepts, in plain English.

The vocabulary every method on this page is built on.

Active recall
Retrieving information from memory rather than re-reading it. The act of recalling strengthens the memory far more than passive review.
Spaced repetition
Reviewing material at expanding intervals over time. Spacing reviews dramatically improves long-term retention compared with massed practice (cramming).
The forgetting curve
Ebbinghaus’s finding that memory of new information decays exponentially unless it is reinforced. Spaced repetition schedules reviews to interrupt that decay.
FSRS
The Free Spaced Repetition Scheduler — a modern algorithm that predicts your personal forgetting curve for each card and schedules the next review at the optimal moment. MintDeck uses FSRS.
The testing effect
The robust finding that being tested on material produces better long-term retention than spending the same time studying it.
Interleaving
Mixing different topics or problem types in one study session rather than blocking them. It feels harder but improves the ability to discriminate and apply knowledge.
Desirable difficulty
A level of challenge that slows learning in the moment but improves long-term retention. Effortful recall is the point, not a bug.

Put the science to work.

MintDeck uses FSRS to show you each card at the right moment. Studying is free and needs no account; AI generation uses credits.
