Spaced repetition is a learning technique that shows flashcards at increasing intervals. Cards you know well are shown less frequently, while difficult cards appear more often. Protutor uses the proven SM-2 algorithm.

Go to "Flashcards" and click "Review Now" when cards are due. Press Space to flip a card, then rate your recall (1-4). The system will automatically schedule the next review based on your performance.
