Spaced Repetition Timer
Enter your exam date and today's date to generate an optimal study schedule based on spaced repetition principles. Improve long-term retention with scientifically backed intervals.
How Spaced Repetition Works
Spaced repetition leverages the psychological spacing effect: information is better retained when learning sessions are distributed over time rather than crammed. By reviewing material at increasing intervals, you strengthen memory traces just as they begin to fade.
This tool uses a modified SM-2 algorithm to calculate review sessions. You input your exam date and today's date, and it generates a schedule with sessions spaced at 1, 3, 7, 14, and 30 days before the exam, ensuring you revisit topics at optimal times.
Increasing intervals strengthen memory
