Dear Akash, in 2018 under All India Quota for General Category, 563 marks got a Medical seat. It was 447 for SC category and 416 for ST category. For State Quota, under General Category it was 625. It was 616 for BC, 576 for SC and 563 for ST categories respectively. Cut offs change every year and are dependant on factors like no.of seats availble, no.of candidates appearing for the exam, difficukty of the exam and top NEET score. So if 576 was the cut off for SC category in 2018, you should atleasr score between 600-620.
