Hi.

Good evening it's difficult to get top branches like cs /it because in top 3 iits because your rank is 169 in st category not in all india rank it means first 168 st students above you will get admission first than you and there are not so much seats of st category but you will definitely get seat in any of the branch in top 3 iits and there are some chances of getting cs/it also .

All the best !!!

congrats for that rank , you will top 2 IIts for 100% sure , you can get cse,ece any branch which u want to go for
