Hi, I was planning to take the GRE at-home test soon and I had so many different answers from everyone and ETS hasn't been of much help, their email reply hasn't answered my questions so I decided to ask them here.

1)Approximately what internet speed is required or is good enough to give the test from home?

2)Can we erase the whiteboard whenever I want during the test or can I only erase the rough work on the whiteboard after the test is over and by showing the proctor through the camera?

3)Is there a specification for the dimensions of the whiteboard? Magoosh blog shows a screenshot of someone asking ETS if there are dimension specifications and they said 8 by 11 inches. They haven't mentioned that on their website so what is this? Is this true?

4)I have a 12 inch by 18 inch whiteboard. Can I use that for the exam? There isn't a smaller size available in the area that I live in.

5)Can I use a whiteboard foldable sheet for doing the rough work during the exam?

6)Can I use transparent acrylic/plexiglass sheet for rough work? Will whiteboard markers even work on that?

I'm so confused and I need to order this stuff online as soon as possible before they put the area that I live in under covid-19 lockdown again. Help.

Thanks.
