Dsa Spaced Repetition

Stop forgetting DSA problems you've already solved.

DSA Spaced Repetition uses the proven SM-2 spaced repetition algorithm to schedule reviews at optimal intervals, so you retain what you learn with minimal effort.

Works across 7 popular coding platforms — the widget appears automatically on any supported problem page.

HOW IT WORKS
• Visit any problem page — the widget appears automatically
• Mark it as solved and rate your recall: Forgot, Hard, Good, or Easy
• The algorithm schedules your next review at the perfect interval
• Problems you struggle with come back sooner; easy ones fade away
• Drag the widget anywhere on the page to keep it out of your way
