Colleges in Ahmedabad

Nirma university is better with respect to placements and faculty

I think you will need to score around 90 to 95 percentile to get admission in IIMA with the kind of academic background you have. Also there are individual paper cutoffs as well, which would also be around 90 percentile. Hence if you score more than 90 percentile in both the papers, then you should get WAT/PI call from IIMA.

you should give CAT entrance exam and should secure above 97 percentile only then there are chances of getting admission in IIMA

I think that kerala is quite best

Your score is not too bad. you can go for an MBA abroad after giving an GMAT exam. if you are willing to wait and gain some work experience of 2yrs maybe, then you can expect a better university and maybe scholarships too.

Yes you can. As long as you are eligible as per the X,XII marks criteria (average &get;80 for Science, &get;77 for commerce, &get;75 for arts background), you won't be directly ineligible for IIMA.
But since your score is less in graduation, you need to compensate for the same by getting a higher percentile in CAT. Based on CAT 2015, you will require 99.8+ to be on the safe side for a call from IIMA.
All the Best!
