hi jothi prassana. hope you are doing well. first of all Colleges like NITs and IITs do not have anything like sports quota seats.but colleges like vit,srm,psg,st xavier's,anna university,jamia allah islamaia,university of delhi,thapar ,jadavpur university,  etc have sports quota seats. but yes one thing to keep in mind is that it matters which community belong to and at what level your acheivements are. cse in vit,thapar,srm is really good.

hope this helps
