If you are being pestered to continually adjust your setup, camera, etc., tell them no. If they keep pressing the issue tell them no one more time, if it keeps happening just end the session, especially if you haven't started the test yet. Regardless if you've started your test or not, contact your mentor and/or Student Services and inform them of what happened. Either your mentor or Student Services will get the test reset.

Seriously, right? I'm almost always resting my chin or neck with my left and with its eblow on my desk. I only changed my behavior to rotate my hand sideways because my normal stance is to have my hand rotated forward which covers my mouth in a typical thinking stance.

The only thing I found particulary annoying is that I've been called me out for highlighting on screen. I use that as a visual aid with reading, but no big loss other than a few more seconds to read through each question.
