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 IMPROVEMENT LOOP
Practice
High-fidelity simulations that mirror CAT's look, flow, and pressure. Perfect practice through data-driven focus.
Analyze
Deep post-exam intel. We analyze factors like unattempted high-ROI questions, time spent on incorrect answers, stamina decay across sections, silly mistakes vs conceptual gaps, and selection accuracy.
Improve
Strategic feedback feeds directly back into practice. Protect strengths, fix weaknesses, and optimize your trajectory.
Inside the CAT Engine
Experience what sets Catalyst apart from standard mock platforms.
The Foundation
A real-exam-like test interface that mirrors CAT’s look, flow, and pressure. It feels like a simulator but functions as a true evaluation engine.
A certain sum of money is divided between A, B and C in the ratio 3:5:7. If B's share is ₹1500, find the total sum of money.
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.
You selected Option B. Correct Answer is Option D.
Reflection Required
Why did I get this wrong?
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.
BUILT TO TAKE YOU TO THE 99TH PERCENTILE.
We stripped away the fluff and designed a system that respects your ambition. Clean, fast, and relentlessly focused on your score.
Score Waterfall Analysis
We show you your true potential. The Waterfall visualizes the gap between your actual score and what you could have scored had you avoided silly errors and trap questions.

Time Efficiency Matrix
Pinpoint time-sinks. We categorize answers into Quick Wins, Wasted Effort, and 'The Death Zone' (questions taking >4 mins that resulted in errors).
Strategic Decision-Making
We track your "Exam Maturity"—your ability to identify easy marks and avoid the 'Death Zone' traps. It's not just about what you solve, it's about what you choose to skip.
- Selection QualityAvoiding low-ROI traps.
- Question PickingFinding the easy marks first.
Personalized Practice Engine

Algebra: Linear Equations
Accuracy stuck at 35%. You are misinterpreting variables in word problems. We need to fix the conceptual translation step.

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.
