What is the lowest undergraduation percentage to get into IIM Ahmedabad or old the IIM?

I know someone who got admission at IIM Ahmedabad and here is his profile.

• Work experience- None (0 years)
• High school percentage- 91.45%
• Intermediate percentage- 76.33%
• Undergraduate percentage- 67.21%
• CAT score: 98.85 percentile

However, I will advise you to not concentrate on these trivial facts. Prepare well and give your best in CAT.
If you manage to score a percentile of 99, then you can confidently anticipate a phone call from any old IIM. After that, it comes down to the way you present yourself in the GD PI round. That would eventually be your real test.
