hi,

IIts, iiits, nits and government institute are best in terms of fees structure, quality of education, faculty students ration etc. however In india there is few private university or institute available where  good quality of education in provided. some of the top private institute are:

thaper institute of engineering and management

vellore institute of technology

lovely professional university

sastra university.

so you have to chose college very carefully and check students review, placement records before taking admission.

hope it would help.
