Colleges in Tamil Nadu

If you have good score in ICAR then surely you will get a seat in TNAU.

Satyabhama is a good idea than Hindustan but no university offers cent percent placement. It depends on your academic side if you are good enough in your studies surely you will be placed.

Placements for computer/IT in VIT are fabulous. I don't know about the other two colleges but have heard good about MIT's placement as well.
