Course fees for Civil at CBIT is 8 lakhs, Mech at vasavi is 6.40 lakhs, ECE at MGIT is 3.51 lakhs

CBIT has a better NIRF ranking than Vasavi, however cannot be said for MGIT with surety

However in terms of employability and types of companies available and differences in skill sets acquired, ECE comes first, Mechanical comes next and then comes Civil.

So choose according to your interest and passion as this would decide your career

These are the ratings of CBIT :

Academics : 8

And these for Vasavi :

Hope these ratings would help you choose a college and for choosing the course I'd strongly suggest you take up whatever interests you the most. Investing 3-4 years in something you hate wouldn't prove all that beneficial, just because everyone said it's good.

Good luck! :)
