Better go for the main campus in Chennai. Nothing beats the exposure there. Kattankulathur campus is way better in terms of infrastructure, facilities, placements and exposure. I understand that NCR campus is close to your home but it doesn’t give u that many opportunities. Since u have a very good rank, better go to Chennai.
Also, many North Indians are present in the main campus. So u ll easily feel at home there.
Also the students studying in Modinagar or any other campus have to come to the main (kattankulathur) campus during placements.
