I have a few friends from Kongu Engineering College and according to them, North Indian students are treated like native students.
North Indians don't have to worry as you won't be feeling that you are in a different state. Everyone will treat you as equal. There won't be any partiality in teaching or hostels. You will feel comfortable studying at Kongu Engineering College.
Maybe you will face a little problem due to language. But apart from that, North Indian students don’t face any problems.
