NIT Surathkal - National Institute of Technology

IIIT H is the best among all. It is even better than many of the IITs in the case of graduation outcomes on the basis of computer Science. It is primarily focused on IT field. Go for it.
Cheers.

Hello,
Hope you are doing well. NITK considers category ranking for cutoff marks. For General, the ranking lies between 400 to 1450.
For OBC category, ranking lies between 450 to 1543.
For SC category, ranking lies between 45 to 650.
These all are the home state board ranking criteria. Other states students' criteria may vary.

I think, CSE at IIEST, Shibpur will be a better option.

You'll not get NITK with these marks. Nor any of the NIT. I would suggest you to go for other private colleges for B.Arch . Moreover, for government, there are least hope with colleges with home state quotas. Best of luck.

No, NITs take admission only through JEE Mains.

It depends on the area of job you are seeking for.
Minimum salary offered 4-5 lakh p.a.
