@NatalyaD you have a typo in that first hashtag BTW, which I only mention in case someone is following the hashtag. I have thoughts about this, but I think it ultimately depends on a few things.
What is causing that initial anxiety about going to class? Is "going there" the problem or is "being there" the problem? Is there a way for attending students to go back and find information they missed? Can they make recordings? Do the slides get published? etc.
Also, I think you're right that a lot of students go to university because "That's what people do", or because that's what their parents want. I know AutDHD can make information absorption more difficult but it can also just murder the motivation to learn. So I think it's important to identify whether the students do have a reasonable way to access the information they missed and are just struggling to find motivation, or whether there is a genuine barrier to information access.
Sorry for the premature send; that's what using a keyboard gets me, I guess.
