Why We Only Take 15 Students Per Mentor

Not a scarcity trick to make seats feel exclusive. It's the actual math behind a 15-minute session — and what happens to that math past 15.

"Only 15 seats left" is a sentence that shows up in enough marketing that it's reasonable to be skeptical of it anywhere you see it — including here. So instead of asking you to trust that the number 15 means something, here's the actual arithmetic behind it.

The math the ratio comes from

The daily check-in runs for 15 minutes. Inside that, there's a fixed cost that doesn't scale with batch size: roughly 2 minutes for the mentor's opening framing ("here's today's focus") and closing note. That leaves about 13 minutes for individual check-ins.

Divide 13 minutes across 15 students and each one gets 45–50 seconds — planned, actual, a quick look at their work if relevant, one clear priority for tomorrow. That's tight, but it's enough time for an honest, specific exchange rather than a rushed "did you study, okay good, next."

Divide the same 13 minutes across 25 students instead, and each student gets 30 seconds — not enough time to say more than "yes" or "no" to whatever the mentor asks, which turns the whole session into a roll call instead of a check-in. Push it to 40 students and the session either runs 40 minutes (which stops being a light daily habit and starts being a chore students skip) or each student gets 20 seconds, which is functionally nothing.

15 isn't a marketing number. It's the largest batch size where every student still gets enough time to say something real.

What breaks first when the batch gets bigger

Not the mentor's effort — the specificity. A mentor with 15 students can remember, without checking notes, that Priya's plan fell apart on weekends and Rohan's biggest gap is Organic Chemistry, not general knowledge that they're "a JEE student." A mentor stretched across 40 students defaults to generic questions, because genuinely personal follow-up requires holding that many individual contexts in your head at once, every single day, and that stops being realistic well before 40.

The entire value of a daily check-in over a WhatsApp broadcast or a generic reminder app is the specificity. Break the ratio, and you've quietly rebuilt a broadcast with extra steps.

Why we don't just hire more mentors and keep the batch small

That's actually the plan — more mentors, more batches of 15, not fewer mentors handling more students each. The constraint isn't "how few mentors can we afford," it's "how many students can one mentor actually know well enough to be useful to." Scaling the program means adding batches, not stretching the ratio inside a batch past the point where the check-in still works.

What this means if you're applying

If you're weighing whether the Lakshya Program is worth it against your kid's time, the batch size is part of the actual answer, not a sales detail: your check-in stays a specific, remembered conversation with a mentor who knows your particular gaps, for as long as you're in the program — because we've deliberately built the group small enough for that to keep being true.

If that's the kind of daily structure you're looking for, apply for the Lakshya Program.
