Why I Treat Every CAT Mock Like a Diagnosis

Someone messaged me last week with a question I get a lot.

"Sir, which book should I start with?"

I understand the instinct. When you decide to prepare for CAT, the natural next step feels like: pick a book, join a course, start solving.

But I made that same mistake when I started.

My first mock was around 60 percentile.

And my first reaction was to just study harder. More questions. More hours. More books.

It didn't work.

What actually moved the needle wasn't more effort. It was a different question.

Where am I actually losing marks?

Not "what should I study" — but "what is actually broken right now."

That one shift changed everything for me.

Every Sunday, I'd give a mock. Then, instead of moving straight to the next topic, I'd sit with the result.

Where did I lose marks?

Which concepts did I not understand?

Where was my accuracy poor?

What should I actually study next — not in general, but for me?

That process took me from 60 to 80 percentile in a few weeks. Not because I suddenly became smarter. Because I stopped guessing and started diagnosing.

Theis is exactly the Mistake I See Most Aspirants Make

Most people prepare in the order of what feels productive, not what's actually needed.

They start with Quant because it feels satisfying to solve problems.

They pick up a VARC book because someone recommended it.

They join a DILR crash course because everyone else is doing it.

None of this is wrong exactly. But it's prep without a map.

You can't know what to fix if you don't know what's broken.

I see this pattern constantly — aspirants three months into prep, working hard, but their percentile barely moving. Not because they're not putting in the hours. Because the hours are going into the wrong places.

This is What I'd Tell My Own 60-Percentile Self

If I could go back and give myself one piece of advice before I started preparing, it wouldn't be about a formula or a shortcut.

It would be this: figure out where you actually stand before you decide where to go.

That's a smaller ask than it sounds. It doesn't need months. It needs one honest look — at your Quant, your Verbal, your DILR, your interview readiness — and a clear read on what's actually holding your score back.

That's the exact process I now sit down and do with aspirants I mentor. Not a generic study plan handed out to everyone. A real look at where someone stands, and what their next 90 days should actually focus on.

If you're at the stage I was at — unsure where to even begin, or stuck at a percentile that isn't moving — this is usually the better starting point. Not another book. Not another course. Just an honest diagnosis first. Either way — start by figuring out where you actually are. Everything else gets easier after that.
