What's inside

Everything you need, nothing you don't

Built around the loop that actually moves your percentile: practise, capture every mistake, review on a schedule.

Real test engine

Topic tests or full mocks from real CAT PYQs, attempted mock-platform style with a question palette, sectional timers and full-screen focus.

Error log + spaced review

Every wrong answer logged automatically and resurfaced tomorrow, in 3 days, then a week, until you master it. Add photos and notes too.

Per-test analysis

Score, section split, accuracy by difficulty and topic, and exactly what to fix next, for every test, plus trends over time.

Chapter-by-chapter PYQs

Attempt past-year questions inside each chapter with instant grading, worked solutions and a progress bar that remembers where you stopped.

Speed math trainer

Daily 60-second drills to sharpen calculation, with streaks and weekly progress, the warm-up that compounds over months.

Synced everywhere

Sign in once and your error log, history and progress follow you across every browser and device. Pick up exactly where you stopped.

The loop

How it works

Practise

Take a topic test or full mock, or work through a chapter's PYQs. Real CAT-level questions, timed like the real thing.

Capture every miss

Wrong answers flow into your error log automatically, tagged by section and chapter, with the solution attached.

Review on schedule

The log brings each mistake back on a spaced schedule until it's mastered, so weak topics turn strong.

A peek inside

Real screens, built for focus

No clutter, no ads, no 40-tab chaos. Just the tools that move your score.

Answer one, exactly like in the app

A real CAT question, fresh every day. Click an option for instant grading and the answer.

Q. The price of sugar rises by 25%. By what percent must a family cut its consumption to keep its total sugar bill unchanged?
Reduction = rise / (100 + rise) = 25 / 125 = 20%. In the app, a wrong answer here would go straight to your error log. Track every answer →

Weak topics turn strong

Targeted drilling on exactly the topics your data flags, not random practice.

You walk in confident

You've seen the question types, timed yourself, and closed your gaps, methodically.
