Dear Laxmi, as a candidate of General Category you should score atleast 50% of the top NEET score to be qualified. For example, if top NEET score is 600, you should score 300 to be qualified. However not every qualified candidate can get a medical seat. In year 2018, cut of for Genersl Category was 119-691. Cut off changes every year and is dependant on various factors like No. of candidates appearing for the exam, no. of seats available, difficulty of the exam and top NEET score. Then there is Statw Quota and All India Quota  So for a seat in  a Private Medical college, your score should not be anything less than 550. However if you have any State or college in mind, please do let us know and we will help you.

Dear aspirant ,
A score of 450+ plus and a rank of 60000 or less will be ok for getting into the private medical colleges .

Hope it helps
