One thing for any return (and there is no timeline, so there’s no hurry) is to keep the courseload low. It isn’t so much academic difficulty of the classes as it is difficulty staying oriented and organized. Yes, it makes it take longer, but at least at first, success breeds success.
In our case we wanted access to grades and his advisor. We had weekly check ins but not much more. Took two tries to go back and stay there (old panic habits are hard to lose) but just go slow and you’ll be okay.
