IIT

step 1 jee main
step 2 jee advance

when compared to least ranking IIT's .top ranking NIT's are the best

Obviously,because every IIT has a world rank,the syllabus accepted by the Brand MNC'S so It is really "best" choice to do it from iit.

Hello ! since you have not done well in JEE mains , dont worry there are still many colleges who conducts their own entrance examination.These colleges are doing equally good as top Government institutions,so why to waste your precious one year when you are having a good colleges to get admission.here are some of the colleges where you can get admission:
1.Lovely Professional University
2.BITS
3.Symbiosis
i have heard that Lovely Professional University provides scholarship upto 1.5 lakh per annum based on your score in their Entrance exam.even these universities provides assured placement.

No this is not possible why do not you try agian or any private uni

I think u r not aware of the fact that the institutes u r trying to compare are from different domain. Former ones are premier in engineering/technology and the later ones are superior choice in management. So there is no comparision dear. Thank you.
