Can I get a gov MBBS seat for 420 marks in neet?(OBC)

Hello student,
You have not mentioned which state you belong to. With a score of 420 in OBC category it becomes difficult to secure a seat in the government medical colleges when comparing the results of previous years. Last year,  a score of 500 or above remained to be a safe zone for the general category under the state quota. But scores and ranks vary each year with toughness of the exam and availability of seats. However you can predict the colleges which you are likely to get using the given link
