You haven't mentioned your Category and the State you belong to. 15% of the seats in GMCs are filled through All India Counselling and the rest 85% are filled through State Counselling and for this you need to hold the domicile of the State. For example if you belong to General Category, you will atleast need 575 and more for State Counselling and you will need atleast 500 if you belong to Reserved Categories. Again this is not for all States because few States like Bihar, UP, Rajasthan and Delhi have higher cut offs than other States. Now coming to All India Counselling you will need atleast 600 and above for a seat under General Category and 550 under Reserved Categories. Now cut offs change every year and are dependant on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam.
