B.Tech Computer Science and Engineering

Hello Himanshu,Yes, you are right. Tamil Nadu allows admissions to it's colleges running Engineering courses to only domicile of the state. I am attaching a link that will give you all the required information. https://www.shiksha.com/university/anna-university/tnea-exam
However, all is not lost. Just apply on it's web portal and wait. There is something called all India quota that normally nobody talks about. Also colleges where seats are not filled invariably put pressure on government and finally some students do get admitted even if they do not belong to Tamil Nadu. It's only a gamble, but then it costs nothing. Do why not try it? Best wishes to you.

Environment is good. Seniors are always friendly. No ragging. Ragging is prohibited strictly. Punjabi food is nice. So, obviously mess food is average. Various events. There are various clubs like LADS, MADS etc. For co-curricular activities. You will get exposure to brilliant minds (I am talking about seniors and not faculty).
Placements for all branches are good. If you are in top 10% of your branch, than there are more opportunities. Training and placement cell works in a better way. Its not cumbersome to get NOCs, training letters. They always give their best to increase placement records. Campus's greenery is beneficial. Campus is clean most of the times.
