I took the At-Home GRE this Sunday 4/5/20, on my MacBook Air with a free copy of Windows installed on a 36GB hard drive partition via Bootcamp (Applications/Utilities). The proctors were not too strict, other than the fact that I had to be on camera all times and show them my wrists, ears, glasses, etc.

I did well, but not my best. My order was QVQVQ, and I think either the 2nd or 3rd quant section was the experimental section.

The score wasn't quite up to my high standards, but the conditions were not optimal, and I treated it mostly as an experiment anyway, so I'm OK with that. My entire family was home at the time (obviously), and although my wife tried to keep the kids on the quiet side, we have 3 of them, including a 2-year old, and as any parent knows, you can only do so much. ; ) Before the exam, my internet connection was diagnosed as "sub-optimal" in my daughter's room, the only suitable room for the exam (which also happens to have the worst wireless reception in the house), so the exam ended up taking 50% longer than it should have (see picture below) after I lost my connection 4 or 5 times, even having to reboot my computer twice and log back into my ProctorU account.

Did I miss the relative quiet and reliability of the testing center? Yes, definitely--but that's simply not an option right now. However, taking the GRE at home was also supremely cool, despite all the technical snafus, and I can see it being perfect for someone who lives alone in a quiet apartment with a fast, reliable, wired internet connection--or someone who has access to a quiet hotel room or office with similar amenities.
