We analyse 15,000+ real JEE Main questions from 2010-2026 to identify statistical patterns in how topics are selected. Each question type is scored across 10 independent signals spanning historical frequency, momentum trends, cyclical patterns, and saturation indicators.
Signal weights are calibrated through walk-forward backtesting, where we simulate predictions for past exams using only data available before that session. This ensures our predictions are validated against real outcomes, not overfitted to historical data.
In our most recent validation against April 2026, the engine achieved 88% precision on top 25 predictions across subjects.
