Kanchan,

             As compared to the last few years' cut off marks, I'm providing you a possible list of government colleges you're eligible for with your rank in All India Quota (15%):

• Government Medical College, Tirunelveli
• Rajah Muthiah Dental College and Hos. , Annamalai

Since the closing rank of colleges may change depending upon a few factors, you can use https://medicine.careers360.com/neet-college-predictor to get a most probable list of colleges you're eligible for. You can mention the name of the state you're staying in to get a possible list of colleges based on state quota.

Hope this information will help you.

Regards
