Hello Mahesh,

There are several private institutes in India. And out of that , it is very difficult to pick out top 10 since all may appeal to be good. Obviously, the first rank will go to Birla Institute of technology and Science (BITS) pilani campus and the rest to follow. Hereby I'm attaching a link which gives you the list of top private engineering college enlisted by Careers360 based on NIRF rankings.
