Every year, I get lots of messages the night before Prelims. From students who have been preparing for 14 months. From those attempting it for the fourth time. From first-timers who can't sleep.

Almost all of them say the same thing: "Sir, I feel like I haven't done enough."

I want to tell you something directly: that feeling is not evidence. That anxiety is not data. Your brain, under stress, is terrible at accurately measuring how much you actually know. So don't trust that feeling tonight.

What tonight is actually for

Tonight is not for revision. Not for that one chapter you skipped. Not for the current affairs PDF you've been putting off.

Tonight is for recovery. For letting everything you've absorbed settle. For giving your prefrontal cortex — the part that helps you eliminate options, spot traps, and think under pressure — the rest it needs to perform tomorrow.

Sleep is not a luxury. For an exam like Prelims — where every mark is precious and every wrong answer costs — a well-rested mind outperforms an over-crammed one, every single time.

The morning game plan

Eat a proper breakfast — nothing experimental, nothing heavy. Your brain runs on glucose. Skipping breakfast to save time is one of the most common and most avoidable mistakes I've seen aspirants make.

Arrive at the centre at least 30–45 minutes early. Rushing to your seat with an elevated heart rate costs you the first 10 minutes of the exam — which is often where your easiest marks sit.

And when you get the paper — don't start on Question 1 immediately. Spend the first two minutes scanning. Get a feel for the paper. Let your brain shift gears. Then begin.

On marks, options, and the trap of perfection

Prelims is a game of elimination, not recall. For every question where you're unsure — don't ask "what is the right answer?" Ask: "Which of these can I eliminate with confidence?"

Attempting 90–95 questions with disciplined guessing on 20 of them beats attempting 75 with false confidence. Negative marking is real, but so is the cost of leaving marks on the table. Calibrated risk-taking is a skill — and you've practised it.

You've already done the hard part

The real exam was every morning you chose to open your notes instead of your phone. Every day you revised something you thought you already knew. Every mock test you appeared for even when the scores were disappointing.

Tomorrow is just the expression of that work. Nothing more, nothing less.

Walk in calm. Trust what you've built. Answer what you know, eliminate what you can, and leave the rest without guilt.

Aim. Prepare. Achieve.
