Your academics are pretty decent, although your score in graduation is slightly less but you may compensate it with Xth, XIIth and the score of your Common Admission Test percentile.

Within the OBC quota, if you get 99+ percentile, you'll easily get a call from all the top IIMs like Ahmedabad, Bangalore and Calcutta. Moreover, if you cross 98+ percentile, then you'll definitely get a call from Kozhikode and Lucknow.

So, in all you are in an advantageous position and should try to get as much percentile as you can in CAT. Hope I have answered your question. All the best!
