I have a DAT test scheduled for tomorrow but just got diagnosed with mono. I feel like death and there is no way I can take the test tomorrow. I tried rescheduling on-line last night and today with no luck. What can I do? Any chance I will get a refund and will I have to wait 90 days to take again? Also, should I just not show up tomorrow or do I cancel the test on-line today and try to call someone tomorrow?
