hi,

iit jam exam conducts for admission in various msc courses in iits, however there is few reservations is available for reserve category candidates as well as pwd candidate.

for pwd reservation eligibility criteria is  with any category of disability (viz., blindness or low vision, hearing impairment, loco-motor disability, and/or cerebral palsy), benefit will be given to only those who have at least 40% permanent physical impairment with respect to a body part/ system/extremity/ whole body, etc. Such candidates must submit the Certificate of Disability from a Government Medical Board and should be fit to pursue the Program. The disability percentage of candidates selected for admission under PwD category may also be required to be certified by a Medical Board, duly constituted by the Admitting Institute.

however in official brochure there is no mention of schizophrenia. if you qualify the above mention criteria you are eligible to apply.
