You all raise good points. I understand wearing a mask is a necessary precaution in large public spaces, or when physical distancing is not possible, in some cities. It is difficult to comprehend doing this where I live, where the incidence is very low. They can also just ensure we are the appropriate distance apart from each other.
Perhaps I am selfish, but I do believe when it comes to a licensing exam, that the conditions should be neutral - not working against the applicant.
