What is the recourse for someone who attributes exam failure to the testing environment?

We understand that taking the exams via remote desktop and a new platform environment may cause a lag time for some, however there are trade offs needed to offer this exam remotely. We will continually monitor and seek to improve the testing experience over time. When eligibile, we do offer free retakes for those who do not pass the first time, regardless of why.
