which is best SASTRA UNIVERSITY or SSN COLLEGE OF ENGINEERING?

Academically i'd say both are almost the same in terms.

SASTRA is in middle of the forest. So you can't expect nice places for hanging out and stuff. Even movies places around the college is merely mediocre and play english movies in tamil. So yeah, social life may be at peril, but students always find an alternative and this way they will get closer, make more friends and enjoy in campus. Somehow, you eventually get to indulge yourself in an extra curricular activity like theatre or photography or music. You'll have an amazing time participating in culturals and winning it almost all the time. SASTRA has the best cult team in the state as far as i know. There are many clubs like English lits, drama etc etc!

Will assure a job before leaving the campus. Have an excellent infrastructure and about faculty you can see their profile in https://www.sastra.edu . You will have very good updated info and marks and all of your details in https://www.sastra.edu under parent web interface section. So no point of worry about checking your attendance.

Gives you some confidence about getting a job by having an excellent HR classes from 3rd year onwards. There may be some restrictions during first year but from second year onwards you will see a different sastra.

As Sastra is a deemed university,they keep updating their syllabus! So any graduate from SASTRA will definitely be technically sound!
