I found this on the mba website
The GMAT exam is administered in an individualized
environment with separate workstations.
The test room is subject to audio/video recording.
On occasion, weather conditions or other
circumstances beyond the control of the test
center or Pearson VUE may require a delayed
start or the rescheduling of your test appointment.
If technical problems caused by the test
center or Pearson VUE necessitate canceling
your test session or prevent reporting of your
scores, you will be offered the opportunity to
schedule another test appointment free of charge
or receive a full refund of the original test fee.
Guess now I just wait and see how bad it really gets....bummer as I was looking forward to finally having this over with!
