NMAT

I don't know what your percentile would be. But, definitely, it will be very low. It would not be good enough to get into any good college. I would suggest you to go for a re-take NMAT for any decent chance of making it to a good college.
As per the eligibility, one should have 60 percentile in NMAT, so, you need to check your score card for the percentile.
And, you should have 60% in class 12th and a minimum of 50% in graduation for MBA general and international business programme. And, for all other MBA specializations, a minimum 50% in graduation.
