The first day of school went really well, actually. They are starting slow, with just a half day. Most of it was spent getting to know one another and the necessary evil of training on the Zoom UI. (After all the school has done to get ready for this, it feels cruel to bring up
the many problems of Zoom.) The guy's focus was decent, though, like most kids, he has a lot of trouble with group chats with more than three people.
Some parents wanted more actual academics, but we liked the easing in. Also, I always think of the Finnish school system, in which kids don't learn to read until they're nine and yet get the best test scores in the world on some respected test or other, and I figure we'll be fine.
The informal "recess" after the video calls were over were the best, though. The guy met some of his classmates, befriended them, and played for hours. He has not played with a group in quite a while, and he does not get along with every random selection of kids. He said it was a "super fun" day.
