IIM Eligibility

Hi.
It will depend upon the IIM which you are seeking. For example, if you want to go to IIM Bangalore, which is well known for Human Resource studies, then they consider the 12th and 10th results, which should be above 90% to be in the eligibility criteria.
If you are aiming for IIM Ahmedabad and IIM Calcutta, then there is no such issue. Because they only ask for the CAT percentile which should again be around 98.5+ to get a call for interview.
So yes, you are eligible for IIMs except Bangalore.
Thank you.
If there are further queries, you can always ask.

To be on the safer side, one should get 98+ percentile in CAT.

I am sure you can join IIM after BBA aviation. But the only concern would be getting aviation sector roles from IIMs. Do check their placement data before applying.

You have to get 98+ percentile to get a call from FMS.

After completing B.Com, you can take admission in IIM through the CAT exam.

No, CAT is mandatory for admission into IIMs.

Please check for your eligibility to pursue M.Com from the criteria mentioned below:

Regards.

You have to score above 95 percentile for a safe BET on your entry to IIMs and other reputed colleges.
