Spaced repetition for mastering Data Structures & Algorithms.
Stop forgetting what you solved last week.
You solve 200+ problems, feel confident, then blank out in an interview on a problem you've already done. Sound familiar? That's because brute-force practice without review is wasted effort. Research shows you forget ~70% of new material within 24 hours without reinforcement.
Problems resurface at scientifically optimal intervals. Easy problems fade back; hard ones keep coming until they stick.
Track your coverage across topics like trees, graphs, DP, and more. See what's due, what's overdue, and where your weak spots are.
Get a daily email with your review queue so you never lose momentum. Consistency beats intensity.
NeetCode 150 and Blind 75 are already loaded. Import additional sheets or add your own problems anytime.
After each attempt, rate how it went. The algorithm adjusts your next review date accordingly.
Come back when problems are due. Over time, you build long-term retention instead of short-term memorization.
