However, as per your rank, your chances are nil for any good colleges.

It is quite difficult to get seat through counselling, as your score is not affective. And, on the same way getting seat in civil is not possible. You may try for management quota. If you are in Mumbai region, then Dutta Megha will be the good option.

It is an evergreen stream of engineering. So go ahead.

Following are some of the colleges in Tamil Nadu:
Alagappa Chettiar College of Engineering and Technology
Government College of Engineering, Bargur
Government College of Engineering, Tirunelveli
Government College of Technology, Coimbatore
Thanthai Periyar Government Institute of Technology
Government College of Engineering, Sengippatti
Government College of Engineering, Dharmapuri
