3. Is it allowed if I keep the laptop and whiteboard on the bed and write the test in that setup instead of a table-chair setup?
Here's a quote from MBA.com on
preparing your test-taking environment.
Quote:
Please ensure that your
desktop is clean and that you are not within arm’s reach of books, notepads, sticky notes, papers, pens, or pencils. If you plan to use a physical whiteboard, have it, your dry erase marker(s), and eraser ready.
Now, I have used examity twice - once for the GMAT and another time for a professional certification exam. As per my experience, the proctors tend to take an extremely literal approach. You can't really blame them. They're just doing their job, which is to maintain the integrity of the test. So, I would assume that anything that's not mentioned explicitly is going to raise eyebrows during the test.
Here's an article from
Princeton Review that echoes the same sentiment.
If you think that getting a desk in the current pandemic scenario is going to be a challenge, why don't you write to examity/GMAT Support & check with them?
All the best with your prep!

P.S.: Make sure you mimic actual test-taking conditions (as much as possible) during your mocks. I tried writing a full 3.5 hour mock from my bed last week. At around the 2 hour mark, my legs went numb and I got a severe case of pins and needles.
