Can boarding schools survive coronavirus?

Interesting article.
The pie charts really said it all didn’t it? (Although was curious which “A” school had only 8% international students? Sound low, no?)
I had two questions that maybe someone more experienced might be able to explain to me.
I’m not sure I understood what the net revenue model was. When they say they “discount” tuition in order to draw students, do they mean through FA and scholarships? (I ask because many of the less competitive schools seem to be on the pricier side; not on the discount side — owing to lack of endowment support.). Anyway — I wasn’t sure about this discounting practice and how that happened. Also I was surprised to read that many heads of schools don’t know anything about the admissions process. That struck me as odd. (I guess that’s not really a question but a comment.)
Thanks for sharing!
