After clearing the entrance examination, based on your score, past academics and relevant work experience IIMs shortlist students for written ability test & PI where they will gauge your interest for pursuing MBA.

Good luck!

Hi Siddharth,
Yes, you can do so. You can pursue one course as regular and other from distance learning. But, both the courses are professional courses hence if you won't do the same from any good college it will not hold much value. Thanks.

First thing, it is very difficult to get admission in any MBA college without any entrance test, and second thing is your graduation percentage is also very low. Most of the MBA colleges have eligibility criteria of minimum 50% marks in graduation.
