Dear Rahul, you haven't mentioned your category. Neverthless, in 2018 under State Quota, 533 was the cut off for General Category and this score secured a seat in 3 Government Medical colleges. Under BC category, 519 marks secured a seat in Government Medical College, Bettiah. For SC category, 370 marks got a seat in the same college. For ST category, the cut off was 429 for Derbhanga Medical College. Having said that, cut off changes every year and is dependant on various factors like no.of seats available, no.of candidates appearing for the exam, top NEET score and difficulty of the exam.
