If you don’t have the certificates in required format, then you need to get it in required format in time. If you fail to upload it in time, you will be treated as general category.
Last year, students were given extra time for uploading certificates. Last date for registration was 7 May (in 2015). The students who uploaded certificates in wrong format, were asked to upload in correct format before 15 May and exam was on 24 May.
You should apply again for the prescribed format, I know it will take lot of time for preparing certificate, but if you hurry behind the authorities, hopefully you may get it done in time.
