I see. May I ask how you know if it’s not too impertinent of me?
Also, regarding your last question, if one applies to a prestigious school but doesn’t attend, I feel as though it would show that the student acheived a level of excellence and (likely) continued to exhibit that exilance throughout their undergraduate program. Declining the initial acceptance shows that the student isn’t chasing lables, but is instead showing that they have the wisdom to make choices that would be better for them in the long run. They’re making an wise personal/economic decision, while not letting go of the dream or their aspirations.
