Hello Rashmi,

Of course, IIT Hyderabad computer science is best among all these mentioned colleges, and if we talk after IIT Hyderabad CSE then comes IITs Physics.

All the best.

Hi Rashmi

It's  better if you take any IIT for placements and other prospects. IITs have very modern approach towards education as well as they have best practical sessions, industrial visits and guides for modern industrial needs.
BITS Pilani should be your second choice and DTU should be the last.

Hope this helps you. :)
