Hii aspirant,

Hope you are doing great. You have the chances to get into a good college if you score high in CAT exam that is more than 90 percentile. When coming to your ug if u score more than 80 percentage it is good. Even if you don't get a seat in IIMs you can get into baby IIMs and top B-schools by getting a good score in CAT. So focus on your CAT score and prepare well for your exam.

Hope it helps.

Good luck.
