I am from IIT Roorkee, Metallurgy Branch 2014 (yet to graduate)

10th - 86.4%
12th - 87.0%
NTSE
Graduation GPA 5.5(approx)
Working in startups and co-founder of two.

I want to ask if I score well like 99+ percentile (offcourse which depends on my preparations), what institutes can I make into?
PS: I already know that I won't be able to make top 3-4 institutes.
PPS: If any previous link to such answer exists, please post the links.
Thanks.
