Arnab, AIIMS conducts its admissions through NEET score through All India Counselling. And this is the first time that AIIMS is conducting admissions through NEET score and so it might be tad difficult to predict the score. And PWD is a horizontal reservation within your Category. For AIIMS Delhi, you will need more than 625 while for an AIIMS Nagpur or Telangana even 600 might be enough. So for AIIMS, we would say you should target more than 600. Now if you belong to West Bengal for seat in VMMC or MAMC, you will have to try under All India Counselling. In 2019, under All India Counselling, an All India Rank of 64138 secured a seat in MAMC. This might total upto 550 and above. But this is again 2019 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 for a seat in MAMC or VMMC, we would say atleast 575 and above should be a decent score. Regarding State Medical Colleges, in 2019, under State Quota, an All India Rank of 671354 secured a seat in Nil Ratan Sircar Medical College under UR-PWD after Round 2. That might be around 450-500. But again because cut offs change every year, we would say you should target around 575 and above considering that you have  MAMC, VMMC in mind and these are all filled through All India Counselling because you belong to West Bengal.
