I think Vellore Institute Of technology cannot be compared with IITs, NSIT, NITs.
As far as quality of students is concerned, VIT students get ranks of the order 50,000 – 2 lacs. Whereas In other mentioned colleges, students are in the order of 1-20,000 rank.
And also colleges like Punjab engineering college (Better than most NITs), Thapur Institute, Harcourt Butler Techonolgy Institute , (other good but lesser known ) colleges are excluded and Likes of VIT, which are surviving on false publicity, are included. This is inappropriate.
