What is spaced repetition?

Spaced repetition is a learning technique that schedules reviews at increasing intervals. Cards you find easy are shown less frequently, while difficult cards appear more often. This optimizes memorization by focusing your study time on what you need most.

What is the SM-2 algorithm?

SM-2 (SuperMemo 2) is a spaced repetition algorithm that calculates when you should next review a card based on your quality rating. It adjusts the interval and ease factor after each review to optimize long-term retention.

Can I import flashcards from CSV?
