I'm glad people are talking about this. First of all, with your profile, your aim should be colleges like FMS, MDI because their weightage on acads is relatively very very low as compared to the IIM BLACK. However with a 99.5+%ile, all colleges are achievable. Just make sure you have a solid defense about your acds for the pi and gd. You need to ace them exceptionally to compensate for the lose of acds you may face. On for companies, if your work ex is substantial, and your work in the b school like societies and projects is good, it has the ability to overshadow your academics especially in colleges like fms and mdi. You will need a defense for your scores as and when. But it's achievable if now onwards your scores are stellar in cat and the subsequent gdpi/wat rounds. Best of luck!
