on what basis are just few students being placed in nit's
Hey there!
Placements really depends on a lot of factors. It's not only about the grades but also about what more can you bring to the table. Other skills which might be useful in your job are appreciated. Internships are also appreciated. Also, you need to present yourself in a manner that you look like the ideal candidate. You should be confident and you need to show the recruiters that you are different with which extra courses and internships help a lot.
