hi michel,

I hope you are doing fine. There are more than 50 colleges under anna university. If a college is at top for branch computer science that does not mean that college will be preferred for mechanical engineering also. Ranking varies corresponding to the engineering branch. TNEA counselling is done for candidates who wants to take admission in Anna university and they provide complete list of most preferred college for each engineering branch. I am attaching a link here: Click here (http://www.tnea.in/prioritylist.html)

I hope this answer will help.
All the best for the future!!
