✅ You’re the “Math Whisperer” of Your Friend Group

When your friends are confused about permutations, combinations, or Bayes' Theorem — do they come to you?Do you find yourself teaching others, explaining concepts, or coming up with analogies that make complex ideas simpler? That’s a strong sign that you’ve got both the understanding and the communication skills that ISI values.

✅ You Can Survive on 3 Hours of Sleep During Exam Season

Okay, this one's half a joke (we do believe in sleep hygiene).But the truth is: ISI demands commitment. Assignments, tutorials, weekly tests — the workload can be intense. You’ll need to be disciplined, curious, and mentally tough.If you thrive under pressure, or if the idea of being surrounded by equally nerdy and motivated peers excites you — you're going to love the challenge.

🎯 Bonus Points If You Also:

• Have a habit of reading math blogs, watching YouTube math channels, or solving Olympiad problems for fun

• Have participated in competitions like RMO, INMO, NTSE, or KVPY

• Dream of working at Google, becoming a data scientist, researcher, or professor
