The exam system was figured out by some group in Texas. Their system was approved by the FCC so my local group piggybacked off of the Texas group to do the online exam.
There was a zoom call at a certain time. You had to do certain things to your computer ahead of time to get it ready. When it was time they had me turn the laptop all around to show my room to prove there was no one and nothing other than a plain sheet of paper, a basic calculator, and a pencil nearby. I had to prove the paper was blank and the calculators memory was wiped. I had to have all family members leave the house during the exam. There were five other people on the call all watching me over my camera while I took the test. The proctor took control of my computer to see what I had running and to start the exam. Then I took the exam. I missed one question, but they can’t tell you which one you missed. I really thought I got them all right and it still bothers me not knowing which one I got wrong ;-)
Afterwards the Texas group was given my information and they submitted it to the FCC. I got my license a few weeks later in an email.
I haven't tried online testing yet. I've been putting off upgrading to Amateur Extra class, though I'll probably try one of those online test sessions eventually.
