Interval scheme

  1. 1Schedule at 1/2/4/7/15/30 days from the study date
  2. 2Review the items due on each scheduled day
  3. 3Completing all rounds markedly slows forgetting
Based on the Ebbinghaus forgetting curve: forgetting is fastest right after learning, and timely reviews greatly improve retention. This is the long-term scheme (1/2/4/7/15/30 days); the classic short-interval scheme adds 5 min, 30 min and 12 h checkpoints, ideal for vocabulary sprints.
