You need to have a PWD certificate before hand certified by a District Medical Officer. Once you appear for NEET and you are qualified, you need to visit any of the Disability Assessment Centres listed in the Information Bulletin at https://ntaneet.nic.in/ntaneet/ShowPdf.aspx? and get yourself evaluated. The Board will evaluate and give you a medical certificate whether you can apply for PWD quota in NEET counselling. This document s important to be submitted during document verification for admission in the College allotted. For any guidance during counselling and admission, you can use our MBBS Companion: https://www.careers360.com/mbbs-companion
