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.

Test engine

Mocks that feel like the real exam

Question palette, sectional timers, full-screen focus, and a results screen that breaks down every section. Build a 10-question topic drill or a full 3-section mock from real CAT PYQs.

What the loop builds

Mistakes stop repeating

Because every miss comes back until it's mastered, the same trap doesn't catch you twice.

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.

Questions

Good to know

Is it free to use?

Yes. Percentyle is a personal prep tool, free to use. Just sign in to save and sync your progress.

Are these real CAT questions?

Yes, the bank is built from real CAT previous-year questions, plus generated practice drills for warm-up.

Does my data sync across devices?

Sign in once and your error log, test history and progress follow you across every browser and device.

Do I need to install anything?

No. It runs in your browser. Open it on a laptop or phone and start.

How is this different from a notebook of mistakes?

A notebook is passive. Percentyle resurfaces each mistake on a schedule, grades you, and shows which topics to fix, automatically.

Why this exists

“I'm an engineer, and this started as something small, made with love, literally, for someone I love who was preparing for CAT. I just wanted her mistakes to stop slipping through the cracks. One feature led to another, the messy notebook became a real system, and somewhere along the way it grew into a full platform. So I opened it up, free, for everyone chasing the same goal.”
