Colleges in Delhi

No, NSIT do not provide Admission on the basis of 12th board score. But you can get Anna University (currently ranked 8th by NIRF) on the basis of board score. Anna University is a just below the top 7 IITs and is far better than even lower IITs. So, you can check details about Anna University on Google.

Yes, you can get admission in DTU with 200 or above 200 marks in JEE Mains.

The exact numbers are never revealed. But it has to be the lowest among all other branches. Most of the students don't go for core jobs, and most of the students go for higher studies. Remaining students go for consultancy, analyst or coding profiles.

If you are looking for a B.Tech course, you need an AIR under 100. If you are looking for a dual degree course in computer science, an AIR under 200 should suffice.

Some hostels are 50 years old. Some are just 10 years old. No ragging. The mess food is not that bad, but you will eventually get bored of it very soon.

There are few companies which come to hire engineering physics students in core profile, Boston, Texas Instruments being some of them. Most of the students actually go for other roles such as coding or analyst and some of the students go for higher studies. Being a student of IIT Delhi myself, I know that students of this branch are not that happy with curriculum and unless they have deep love for physics, the students always try to get out of this world of physics.
