I can understand why he wants him to show up to school. I would suggest though that he take it slowly still. Maybe two or three hours a day to start.
And I would suggest that you arrange for him to get the notes from the teacher or another student even if he tries to write notes too.
That way he still has a copy of what is said.

Keep us updated as to how he is doing too. That is what we are here for.
