I am one step away from the selection of railway job.I am physically handicapped person with disability 20%. I am not under PH category for which it requires 40% disability. Then do I come under PH or nonPH? If non PH what is the selection procedure in RRB? If I come under non PH is there any chance to disqualify me in medical tests>? Since I am only eligible for OC category posts. Can you clarify my confusion?
