My girlfriend is at BYU and it's been great. Hybrid classes are a good idea, there are some in-person options for a lot of students, but they also have more online options as well. Library/Wilk is open, as long as you do a five second Covid check on your phone. I'm super jealous. All my classes are online, library is closed, etc.
Everyone hates Covid school. I think it's less a BYU problem and more a ZoomU problem. I would get him to Provo ASAP and find stuff to do.
