Flashcards and spaced repetition, done right
Cramming decays within days. Spaced repetition is the most evidence-backed way to make knowledge stick — if the cards are effortless to make.
Cramming feels productive but decays within days. Spaced repetition — reviewing a fact just before you would forget it — is the single most evidence-backed technique in learning science. The catch has always been effort: making good cards by hand is so tedious that most people never keep it up.
When the cards generate themselves from your material, the technique finally becomes practical. Here is how to use it well.
Why spaced repetition works
Every time you successfully recall something, the memory strengthens and the "forgetting curve" flattens. Reviewing at expanding intervals — a day, then a few days, then a week — schedules each review at the moment it does the most good, so you spend the least time for the most retention.
The active part matters as much as the spacing: retrieving an answer from memory beats rereading it, because the effort of recall is what builds the memory. Flashcards are simply the most efficient way to force retrieval.
Use difficulty levels deliberately
Aurora generates complete decks at four difficulty levels. Start at "Medium" for a first pass to lock in the basics; move to "Hard" or "Expert" once they feel automatic. Those higher levels ask application and reasoning questions — the kind professors actually put on exams — instead of simple recall.
- Easy / Medium: definitions, facts, core vocabulary.
- Hard: apply a concept to a new example.
- Expert: compare, reason, or solve — exam-style.
Turn cards into an honest score
Use Quiz mode for self-testing and finish with a Study Session that ends in a percentage. "Am I ready?" gets an honest number instead of a feeling. Below 70%? Reread only the sections behind the cards you missed — not the whole chapter.
Frequently asked questions
How many cards should I review per day?
Short daily sessions of 10–15 cards are more effective than long infrequent ones. Consistency across days is what drives retention.
Where do the flashcards come from?
They are generated automatically from your uploaded material — lectures, notes or PDFs — so the deck matches exactly what you need to know.
Is active recall better than rereading?
Yes. Decades of research show retrieval practice (recalling from memory) produces far stronger long-term retention than rereading or highlighting.
