I got handed a problem with no playbook. So I built one. Here's what I learned.

In 2020, my manager walked up to me and said: "We're doing a national online aptitude test series. It'll be the backbone of sales conversions for our JEE|NEET classrooms. You're running it."

I asked for the playbook.

There wasn't one.

Online tests at this scale hadn't been done in India before. No template, no senior who'd "been there," no benchmark to copy from.

So we started building — in real time. Every week, decisions without complete information. Some worked. Some didn't. Every failure got documented. Every fix became the next version of the process.

Six months later, BYJU'S National Aptitude Test (BNAT) had delivered:

→ 1,000,000+ unique registrations

→ 3.6 lakh students attended across six months

→ Sales conversions jumped from 2% (organic) to 8–10% via the scholarship test

→ The platform held — and got better with every iteration

Within a year, every major coaching brand in India had replicated the model.

We didn't stop there. We ran the same playbook for BYJU'S AIM — India's largest free mock test series for JEE Main, JEE Advanced, and NEET. Others followed again. Imitation is the biggest form of flattery, after all.

Done and learned beats perfect and delayed. That's the only playbook I had going in — and it turned out to be the only one I needed.

The part that still stays with me: we didn't wait until we had it all figured out. We couldn't afford to. We shipped, broke things carefully, fixed them fast, and kept moving.
