RF: If she didn’t want to go to Harvard then she lost nothing- the fact that it’s so selective is a point in her favor because, after all, she GOT IN. Turning it down is her prerogative.
I have known frum girls who have applied to Ivies just to see if they can get in (I considered it but I decided to save my parents the $200 even though they said it was fine). While most did not get in, as the acceptance rates tend to be in the single to low-double digits, the ones who did turned them down because they were just satisfied knowing that they COULD HAVE gone.
