CAT Quant diagnostic

Three kinds of wrong.
Only one is a concept gap.

Every error is a concept gap, a careless mistake, or a timeout. QuantIQ names which. Most prep tools don't.

What is QuantIQ?

QuantIQ is a free educational diagnostic tool for CAT Quantitative Aptitude preparation. It helps you identify whether a wrong answer was caused by a concept gap, a careless slip, or running out of time — so you study the right thing rather than repeating the same mistakes.

How the diagnostic works

You attempt a short set of CAT-style Quant questions. After each wrong answer, QuantIQ asks you to confirm the type of mistake. Over time it builds a Progress Score per topic, showing you exactly where conceptual revision, slower-and-careful practice, or speed drills will help most.

Conceptual vs careless vs timeout mistakes

Conceptual — You did not know the underlying rule or formula. Fix: targeted revision of the sub-concept.

Careless — You knew the method but made a slip (wrong sign, mis-read, rushed arithmetic). Fix: slow-and-deliberate practice on the same question type.

Timeout — You used a correct but slow method that would cost you in the actual exam. Fix: practice the faster shortcut on the same type until it becomes automatic.

How to use QuantIQ with your current CAT prep

QuantIQ is designed to complement any teaching platform you are already using, not replace it. Use it after a study session to diagnose where you are still making mistakes, then take those specific error types back to your primary study material for targeted revision.

Free vs Pro

The diagnostic — error classification, session feedback, and Progress Score — is always free with no account required. QuantIQ Pro (paid, one-time) unlocks unlimited practice sessions, full error history, Mistake Book, and Progress Score across all 28 topics. See full plan details →
