Your home mock can't test the thing that decides your score

I am going to say something that will sound strange coming from a teacher. The mocks students take today are far less useful than the ones we took ten years ago. Not weaker on paper, because the questions today are sharper and the platforms are slicker and the analysis you get afterwards is better than anything we ever had. They are weaker in the only way that ends up mattering: they don't have worse questions; the way students attempt them is worse.

Let me take you back to 2009, when I was first preparing for CAT myself. Mocks made much more sense then, because we had to physically go to an exam centre to write one, exactly the way we would write CAT itself. We got far fewer of them, maybe ten or fifteen in a whole year, and yet every single one of those was worth about ten of today's, and the reason is simple once you see it. Every mock you take today is taken under conditions you will never experience on exam day. Your own chair, your own room, your own water sitting right there within reach, the fan at the exact setting you like, the timing of your choice, the silence level that suits you, and above all of that, not a single pair of eyes watching you. You are not rehearsing the exam. You are rehearsing a very comfortable version of it that will never actually show up.

Now look at what exam day quietly adds to your desk, none of which your home mock ever charged you for. There is the commute, and the queue outside, and the biometrics, and a slot you did not get to choose. There is a screen and a mouse that might be straight from the early 21st century. There is an invigilator standing somewhere behind you, close enough that you can feel it and he might be a very noisy person for all you know. And there is a complete stranger sitting to your left who finishes the DILR section early and starts sighing to himself, or who takes one look at the QA section and holds his head in his hands. Add to that the real risk of failure. None of that is in your practice. All of it is in your exam.

Even the large number of mocks available today actually works against you. When we had strictly two mocks in a month with no possibility to attempt any later, each mock put us under real pressure because there was no replacing one lost mock, no second chance till the next mock arrives. In the modern era of endless number of available mocks, I see students taking one on Monday and if the score is not to their liking, immediately again on Tuesday - no analysis, no preparation, instant gratification, and no fear of actually messing up a mock because you can always try tomorrow. But isn't the whole purpose of a good mock preparing you for everything that the test will throw at you, including stress and fear?

So here is the part I really want you to sit with. The gap between your home percentile and your real percentile might not be a gap in knowledge. It can very well be because of the tax the real exam environment charges you the moment you step into it, and that tax is not paid out of what you know. It is paid entirely out of your composure.

I will give you the story that made me start saying all of this out loud to every batch. A student of mine sat at 97-99 percentile across eleven home mocks, no fluke about it. He walked out of the real exam at 83. And when we sat down to figure out what had gone wrong, the honest answer was that nothing in his preparation had failed. His concepts were solid, his speed was there, his accuracy was there. He had simply never once, in a whole year, practised being uncomfortable. The exam did not beat his knowledge. It beat his calm, because his calm had never been tested even a single time. And I want you to know that his is not some rare, unlucky story. There are countless students exactly like him, and I watch it happen every single year.

The fix for this is almost embarrassingly cheap, and that is probably why almost nobody actually does it. One mock a week, taken in real exam conditions. That means the same slot time as your real slot, so your body learns to be sharp at that exact hour. No pausing. No water break in the middle. No phone anywhere in sight. And if you can manage it, take that one in a public place - an internet cafe, a library, your coaching center - somewhere slightly noisy and a little uncomfortable and full of stranger faces, because that discomfort is the whole point. That mock, and not the cosy ones, is the one that tells you the truth.

Because in the end, this is the thing that took me years to fully understand and that I now tell everyone as early as I can. CAT is not just a test of knowledge. It is a test of nerves, and of your decision making ability in those moments when those nerves are working against you. If you want to build that side of yourself, you have to put yourself under some real stress at the time of your mocks, on purpose, while it is still safe to fail. Do that, and exam day becomes just one more of those mocks. Skip it, and you have spent a whole year getting very good at one half of the story while completely forgetting that the other half is the one that decides your score on the exam day.
