Hi Prakash.

Considering your score and your category you have pretty good chances of getting a state quota. This reservation Category is only applicable to 85% state quota seats for the candidates belonging to the state of Tamilnadu. So first of all you should be a domicile of Tamilnadu. According to previous year trends I can give you the cutoff for some of the Colleges in Tamilnadu:

Chengalpattu GMC - 367

Dharmapuri GMC - 350

ESI PGIMSR Chennai - 322

GMC and ESIC Coimbatore - 337

Hope this helps.

Good luck!!
