Hello candidate !!

Sorry to say but 314 is a very low score even with OBC reservation if you want to get into a college through All India Quota Counselling.

It would have been helpful if you have mentioned which category you belong to in you state(BC/MBC/BCM/OC/SCA). Nevertheless,this year the cut off has increased. It will be quite difficult to get even through state quota .

Here is a link you can refer for cut off colleges in Tamil Nadu-

All the best.

Hope this helps.
