Netaji Subhas University of Technology Dwarka Delhi Answered Questions

No, you can not, according to NSIT policy your branch only changes with respect to JEE mains rank and not your performance in that particular year which happens in IITs. your branch can change till end of first semester if someone leaves college and a seat becomes vacant according to JEE mains rank.

Anything in NSIT is better than IPU, if only thing you are looking for is placement. All the major companies of mechanical visit NSIT. But if you are interested only in computers than go for MAIT. if you do well you can always land an off campus placement. for comprehensive placement details visit http://www.nsit.ac.in/placement/

No you can not, anybody who takes NSIT, has to attend college irrespective where one lives. if you live far away you can easily get hostel which is cheap and pretty good and easily available. best of luck.
