Hey,

Your academics are pretty low to target old IIMs to be very honest. You need to target at least 99% percentile so as to be considered for the interview of old IIMs. That's too not a surety.

Different colleges have different criteria according to which they prepare an Index score for each candidate. And the students securing above the index score are selected for the interview round.

Try to to score as high as possible. Anything below 99 percentile would make it difficult for you.

Hope that helps.

All the best

Thank you.
