She really loved Northeastern, but ultimately decided to attend NYU. NYU had a program that she preferred outside of its business school that was not available at Northeastern.
BTW, I do not think that she would have been admitted to Stern at NYU if she had applied there. IMO it’s even more reach-y than D’Amore-Kim at Northeastern. But, good that you have a hook at NYU, excellent EC’s & an impressive SAT score (D couldn’t take the SAT due to multiple COVID cancellations).
