Dear Jayadevi,

Thank you posting this question since this would be more useful to others too.

If  you didn't get admission into the colleges of Anna University via the sports quota counselling, and you still wanted to pursue engineering,  I recommend you to go through the general counselling procedures.

But if you think your HSC score is quite lesser compared to other students you compete with, then you can directly contact the college or even universities of your own choice which excels in sports before the mid March. Most of the college in Tamil Nadu select their sports students based on the separate trails being conducted. Performing well in selection trails will surely put you into the college either for free or with some concession.

Hope it helped you
