Why fit is so important

One of my son’s friends went to a non NE boarding school that is often touted as great academically just not in NE so different vibe, etc. His friend frequently face times or texts him from class. Classes look like a zoo so I am on the fence about less selective schools really being as good an academic fit. My kid would have a fit if he ended up at that school and kids were behaving that way in class. I frequently get texts from the kid and he’ll say “I’m in Spanish class and I’m bored, what are you up to?” Yeah, just an anecdote, but a bit odd to me that a school that is supposed to be so high falutin academically is just so lax about class time.
