Spaced Repetition Planner
Turn a learn date into a spaced-repetition review schedule on a proven interval ladder.
How to plan spaced repetition
- Pick the date you first learn the material.
- Choose or edit the review interval ladder (days after learning).
- Read the calendar date for each scheduled review.
Frequently asked questions
What is spaced repetition?
Spaced repetition is reviewing material at growing intervals — a day later, a few days later, a week later, and so on — so each review lands just as you start to forget. It is one of the most effective ways to move knowledge into long-term memory.
What review intervals should I use?
A common ladder is 1, 3, 7, 16, 35, then 90 days after first learning. The exact numbers matter less than the principle of expanding gaps. COSMIQ's tutor uses an FSRS-based scheduler that adapts to how well you actually recall each item.
Sources and methodology
Expanding intervals are supported by learning research, but there is no single best ladder for every learner or subject. The dates here are a planning heuristic; adjust them based on actual recall and use your course or teacher's requirements.
