Three things, done well.
Find your blind spots
A short diagnostic spots which set-types — grids, games, caselets — quietly cost you marks, then weights every set toward them.
Explain why you missed it
Not just the right method. Our AI reads your actual approach and shows where your reasoning broke — the part textbooks skip.
One set a day, that's it
No 40-hour course to begin. A single, real, exam-timed set every morning builds the habit that actually moves your percentile.
Can you avoid the pitfall?
Four friends, four different scores.
- P scored higher than exactly one of the others.
- Q was neither the highest nor the lowest scorer.
- R scored higher than S.
Q1. What did R score?
Q2. Who scored the lowest?
The pitfall: most people start guessing from “R > S” and stall. The key is clue 1 — “P beat exactly one person” means P is second-lowest = 70. Then Q can’t be top or bottom and 70 is gone, so Q = 80. That leaves 60 and 90 for S and R; since R > S, R = 90, S = 60. One clue unlocks the whole chain — that’s the instinct the daily set builds.
The most feared section. Also the most trainable — if you practise the right way, every day.
