❓ Common questions
- How does the Leitner Box 5-box flashcard system work?
- The Leitner System is a proven learning methodology created by Sebastian Leitner. Flashcards start in Box 1 (reviewed daily). Correctly answered cards move up one box to be reviewed less frequently, maximizing long-term memory retention while saving study time.
- What happens when I answer a flashcard incorrectly?
- Whenever you miss a card—regardless of whether it was in Box 2, 3, 4, or 5—you demote it back to Box 1. This guarantees that difficult concepts are automatically funneled back into daily review until mastered.
- What are the recommended review intervals for spaced repetition?
- The standard scientifically backed intervals are: Box 1 (daily), Box 2 (every 2 days), Box 3 (every 5 days), Box 4 (every 9 days), and Box 5 (every 14 to 30 days).
- Why is spaced repetition better than cramming?
- Spaced repetition leverages the psychological 'spacing effect,' interrupting your brain's natural forgetting curve right before recall memory fades. This transfers knowledge into durable long-term memory with less overall study time.
- Can I use this scheduler for Anki or physical flashcard decks?
- Yes! This scheduler provides the master review calendar whether you use physical index cards in paper boxes or digital flashcard apps like Anki, Quizlet, or Notion.
