Your past academics are quite good, especially your class Xth marks. Now, since you belong to the Person with Disability, or the PwD category, thus you have almost every chance to get into the revered halls of IIM Ahmedabad, as all the institutes of National Importance, including IIM Ahmedabad have a special quota reserved for PwD candidates, and the lack of such candidates makes the selection even more easier.

So, prepare well and give CAT and interviews confidently, and you'll definitely succeed. All the best!
