The Problem with Traditional Practice
Without a system, you forget 80% of what you learn within a week. Random problem selection leaves weak patterns untouched.
Based on Ebbinghaus's forgetting curve research (1885)
Built on 40 Years of Cognitive Science
Four proven learning principles, applied to your interview prep.
Spacing Effect
Distributed practice beats cramming. Our algorithm spaces your reviews for optimal long-term retention.
Cepeda et al., 2006 — Psychological Bulletin
Testing Effect
Active recall strengthens memory more than passive review. Every practice session is a retrieval opportunity.
Roediger & Karpicke, 2006 — Psychological Science
Interleaving
Mixing different patterns daily improves transfer to new problems. We intelligently vary your practice.
Rohrer & Taylor, 2007 — Instructional Science
Forgetting Curve
Review at 70-80% retention for maximum efficiency. Our algorithm knows exactly when you're about to forget.
