Who is CATALYST for?

The Committed First-Timer

You don't want to waste 6 months realizing your mocks were inaccurate. You need the actual flavor of the CAT from day one. Start your prep with the exact difficulty, phrasing, and pressure of the real exam.

The Frustrated Retaker

You know the syllabus, but your mock scores hit a plateau. You don't need more generic questions. You need to know exactly why you're losing marks—whether it's stamina decay, toxic question selection, or silly errors.

The Working Professional

Your prep time is limited and expensive. Catalyst helps you make every mock count by showing where time, accuracy, and question selection are actually leaking marks.

The Insight Layer

Post-Exam Philosophy

Most platforms stop at scores. We start there. Weaknesses are exposed with our Reflection Layer, prompting you to tag errors—like calculation mistakes or conceptual gaps. This turns passive review into active learning.

Rational Strategy

Allocate preparation time rationally. Our ROI Map plots Accuracy against Time Spent to categorize topics into 'Cash Cows' (high accuracy, low time) to prioritize, and 'Money Pits' (low accuracy, high time) to avoid.

Frequently Asked Questions

Is this a recurring subscription?

+

No. It is a one-time payment for a full year of access to all features in your chosen plan. There are no automatic renewals or recurring fees.

Which CAT papers does Catalyst include?

+

Every official CAT paper from 1991, 1993–2008 and 2017-2025. Wait, why is there a gap? The papers for the years 2009–2016 were never officially released by IIMs because the exam was transitioning online and the questions were kept strictly confidential. The other 30+ papers we have are 100% authentic.

How is this different from other mock series?

+

Our core philosophy is different. We provide official CAT papers adapted to the current exam pattern. For recent papers, we intentionally preserve the original 66-question format. Because the time limits and structure are essentially identical to the current 68-question pattern, retaining their authentic form ensures the most realistic mock testing experience. We combine this with a realistic interface and analysis designed to provide strategic insights, not just a score.

Which plan should I choose?

+

For the most thorough preparation, just go with the Pro Plan, it is the best value for the money.

Is there a refund policy?

+

Yes, you can get a 100% refund if you meet both conditions:

  • You've attempted less than 2 tests
  • It's within 7 days of your purchase

Go to your Catalyst dashboard and click on the [Help] button to write your message to request a refund (no questions asked).

When will I get access after payment?

+

Instantly. The moment your payment is confirmed, your account will be activated and you'll be redirected to your dashboard to begin.
