Hello Yash,

Applicants claiming for Person with Disability (PWD) quota will be accepted only the applicant is certified with up to 40% of disability and are able of pursuing the activities related to the academics for JEE.

For claiming reservation you need to have a Disablity certificate failing which you won't be given a reservation. Certificate should be authentic and original so that if the authorites require it can be cross checked (in case of any discrepencies)

For PWD students their is 3% reservation in JEE MAINS.
