Why would you question that? My daughter goes to a 2nd level, party school - College of Charleston. She is very challenged. My son - same at Alabama.
It depends in part on the kid and the major.
Some will coast - but I’d say that’s more major specific than the kid.
I’m sure they can find rigor at UMASS or BU - and at both can find majors that are less challenging.
I don’t think one can take size and reputation and assume is all I"m saying.
