I didn’t mention the differences among the schools but I think they’re highly salient. Said another way, what’s the running thread beyond that they’re all TSAO? There are large and small, rural and in-town and close to city, all/mostly boarding and lots of day students, strictly harkness and mixed methodology, etc etc etc.
Are they all great academically? Sure. But if that’s the only common denominator then you should add another 10, 20, or 50 schools
