which safe score for hearing handicapped for sc category to get medical college??

A hearing disability upto 40% is considered eligible for PWD reservation in NEET. And PWD is not a vertical reservation. It is a Horizontal reservation within your Category. Now assuming you are eligible for PWD reservation, coupled with SC reservation, you wil atleast  need 500 for a seat in a Medical College. This might change based on the State you belong to. And this is just based o previous years 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.
