Michelle - NO! There isn't. I definitely tried too. It's probably the most useful feature in the simulator, certainly more so than the ability to mark questions. I missed having it there, but not having it didn't cause any issues.
Mohammad and Stan - thank you for the positive words.
Indeed, communication was set up before the exam but only via the text chat. The proctor who was present during the beginning of the exam rotated out at least twice, perhaps more. The introductory instructions only relate to the UI itself, without specific instructions on the structure of the exam (i.e. 120 questions, no break). Those people reading this should be keenly aware that the proctors are primarily there to police your behavior. Ask them anything else and you may get an unreliable answer as I did.
If anyone has any other questions for someone who just recently took an electronic exam, I'll be checking this thread in the week ahead. AMA!
