Hello Ayush.

As you are talking about best college it could be very much away from your home city if I tell in random. It's better if you tell us your home city and all.

By the way few all India colleges are.

1)Department of computer science, Savitri bai Phule Pune University.

2) JNU Delhi.

3)NIT trichirapalli.

Etc.

Hope you get it.

Good luck
