I was schedule to take the CISSP exam awhile back and came down with Covid. Trying to be responsible I advised the testing center and ISC2 of the situation and DID NOT go take the exam. I am not thinking I should have gone and taken the exam because I was told I would get a test voucher and never have. I have emailed ISC2 several time with them always kicking the can down the road and not giving me a test voucher.
My message to everyone is go take the exam even if you have COVID. ISC2 will NOT give you a voucher to take it later and will keep the money paid for the exam.
