Candidates must upload a passport-sized color photograph (20 KB to 50 KB, preferred dimensions 200 x 230 pixels) and a digital signature (10 KB to 20 KB, preferred dimensions 140 x 60 pixels) in .JPG or .JPEG format. For candidates claiming fee concessions (SC/ST/North-East residents), a scanned copy of the valid certificate (less than 1 MB) must be uploaded. Failure to meet these file size and type constraints will prevent form submission.
