Anki FSRS Algorithm Settings for Cramming Exams in Under 14 Days
Anki's FSRS (Free Spaced Repetition Scheduler) replaces the legacy SM-2 algorithm by modeling memory stability and retrievability. For short cramming windows (under 14 days), set Desired Retention to 0.90, enable FSRS in deck options, and use Custom Study filtered decks with 'is:due or is:new' tags.
The default Anki algorithm (SM-2) was created in 1987. In 2026, FSRS (Free Spaced Repetition Scheduler) is the modern standard for rapid learning.
By predicting memory stability using modern machine learning models, FSRS reduces study time by 20–30% while maintaining a 90% retention rate.
