Hi Prateeksha!!! Congratulations on your score but I am sorry to inform that you won't get a government bds seat in Tamil Nadu or anywhere in India and in TN the cutoff has been 529 under 85% state quota for OBC students, so you have to try for private colleges , to know which college are you eligible for with this score visit https://medicine.careers360.com/neet-college-predictor

Hope it helped.Thank you
