Wow. How would the school know which students attended? What business is it of the school’s what students do when not on campus?
When I was at college years ago the school had no inkling what I did off campus. I went to class or library & went home. Went to many parties - off campus.
Schools are busybodies now. Even CLOSED colleges in CA require students living in the college town to get tested weekly. Even WITHOUT opening the campus to them, at all.
