As per the last year cutoff based on this rank the chances seems less to get a seat under 15% quota seats but you can have the chances for state quota seats in Tamilnadu.

Good Luck!

Hi Vishnu Priya,

Based upon your score in NEET 2018, and the previous year cutoff, chances are less for admission to Government Medical Colleges under All India Quota. You may have chances for admission to government colleges under state quota.
