This is something that I've been ruminating for a few weeks (post M10) now...
For the two boarding school application cycles that I've been witness to here on CC, I've seen many (a majority?) prospective applicants apply exclusively to the most selective schools. And, along with other parents/current students, I've tried to make a case for considering a broader set of schools *and taken my share of lumps in the process.
I want to articulate my POV in another way:
Imagine a high school junior or senior who came out and said that they were only applying to the most selective colleges the so-called HYP+MS (Harvard, Yale, Princeton, MIT, Stanford) group?
Isn't it conceivable that a well-intentioned parent, friend, teacher, or guidance counselor would advise the kid to perhaps expand their scope?
I think so. Even if the kid in question had great scores, a great GPA at a rigorous school, strong ECs, etc. So why it is so crazy to suggest that most BS prospects would be well-served to consider a wider set of schools?
