Hello aspirant!
Hope you are doing well.

They are not enough marks to get any government medical college for obc category. In order to get any government college you must score 600+ marks.
But yes you can get private medical colleges in Tamil Nadu, here I am providing you a list of the private colleges which you can get:-

• SRM Medical College Hospital and Research Centre, Chennai
  
• SRMCRI Chennai - Sri Ramachandra Medical College and Research Institute
  
• PSG Medical College - PSG Institute of Medical Sciences and Research
