I don’t know, but I would think your chances would be better during ED…They are going to balance students with need vs those without so there would be more “need” slots the earlier you apply I would imagine.
But in general,
Is there a difference in financial aid awards for ED students (or EA or RD)?
This one is easy: Nope! We meet 100% of demonstrated financial need for all admitted students, regardless of their admission plan. (You may want to review our financial aid application requirements if you have not already started this process.)
