Hii vaidehi,

Coming to your question it is not clear to clear to me of what exam you are asking for but assuming it as afmc exam ( armed forces medical college) , I would like to say that a injured person can apply for this but the disabled person could not apply for this exam. According to the medical conditions which is issued by the AFMC.

Hope this is clear to you if my assumption is correct, if not just put a comment what exam you are asking for,

Good luck.
