I’ve seen a lot of kids with some amazing hooks throughout the years . I’ve also witnessed kids abandon their hooks ( before college ) because they’re miserable in the wrong BS environment, too . Call me crazy but…
You’re the one going @applier1 not your parents and you shouldn’t need a power point presentation to state the obvious. Your parents are making a poor decision ( or a lousy ultimatum ) based on a false premise. Period.
I’m a past parent of two former “Top” BS kids and one " HG " kid. I’m also a former Trustee at my BS ( along with other former Trustees at their BSs like my husband, father in-law, some sibs, father, grandfather and some uncles- over a span of many, many years ). I’m a 3G BS alum and my husband is a 2G. You want to talk BS shop? Come to my house on Thanksgiving or Christmas! We’re already gearing up for some 5Gs on my side of the family!
Hopefully, I’ll be dead by then… 
The “best” BS simply does not exist. There is no such thing as a BS Hierarchy. That’s just ridiculous and all the young alums in my family would tell you the same thing , too- after they pat you on your head and gently mock you. But here’s the really unfortunate thing: Some people just don’t get that until they get there and it’s too late. IDK about you but I wouldn’t want to be that kid or family…
Here’s the bottomline: If you think you can thrive and be happy at Andover - GO! But at least be smart about it and compare it to at least one other school.
