Hi sir this is Vijay my neet score 510 marks and EWS certificate available eligible government college or not please tell me sir
But you can expect a good government medical colleges in your State quota. I would suggest you to use our Neet college Predictor tool to know where you have good chances http://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer
see cutoff score changes every year and it depends on certain factors like number of applicants, questions difficulty level, seat matrix, students category. you did not mention which of the states you belongs to. there is separate closing rank is given for state quota and ALL india quota. do mention the state of domicile name in comment section.
however you may use careers360 college predictor tool to know about your probable college name,
