I am assuming you are from general category. A lot depends on your profile. Assuming you have a decent overall profile(85%+ throughout), you will be needing above 99.5 percentile to get a call for the next round.

All the best!

Hi Aashish,

IIM-A is the topmost B-school in the country. The Institute generally shortlists the students who score 90 percentile or above in CAT (General Category). However, that's just the short-listing criterion. There are other factors on which the final admission depends such as Written Ability test, Personal Interview, Past Academic Performance, Work Experience, Diversity etc. The weightage given to each factor is different. To know more about it, please check the details available at the link given below:
