You haven't mentioned your Category. But MS Ramaiah is a Private Medical College. If you belong to General Category, you will need atleast 500-550 and if you belong to Reserved Categories, you will need atleast 450-500. Now this is based on previous years cut offs. But cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam.
