If your CAT score is above 99.90 percentile, you will have a decent chance of getting an interview call from IIM Calcutta.
IIM Ahmedabad and IIM Bangalore assign good weight to past academic records for the interview shortlist. You need to have a consistently good record throughout your 10th, 12th, and graduation to get a call from IIMA and B. Having relevant work experience of a minimum of 2 years is also important if you are targeting IIMB.
IIM Ahmedabad and IIM Bangalore are allegedly very specific about their academic profile and they particularly take into consideration your graduation percentage.
These are the cut off percentile usually required for a candidate (general category) to become eligible:
IIM Calcutta | IIM Bangalore | IIM Ahmedabad |
99 | 99-100 | 99-100 |
These are 2021 cut-off percentiles of the top three IIMs. In 2020 the cut-off percentile might have been lesser, being 85-90. This year it has increased.
