Dear Praful, PWD is not a vertical reservation. It is a reservation given within your Category. For example lets say if you belong to General Categor, you will be eligible for General Category - PWD reservation. But you do not get separate reservation. In 2019, Bihar had one of the highest cut offs for its State MBBS seats. Irrespective of your Category, you should aim for atleast 600 for a seat in Patna Medical College. Now this is based on 2019 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. The cut offs might decrease with increase in the no.of availability of seats. Considering all these factors, 600 should be an ideal score.
