Vaishnavi, you havent mentioned your Category. Neverthless, 463 was the cut off for Government Quota seat in JNMC under General Category. It is much lesser in Reserved Categories. Now this is previous year's data and cut offs change every year. 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. So if you belong to General Category, you should aim for atleast 525 and if you belong to Reserved Categories, 500 should be a good score.
