You mentioned earlier you planned to email your Wellesley financial aid counselor; have you done that?
I’m very concerned that your generous aid from Wellesley was calculated incorrectly. Wellesley does not give merit scholarships, nor would they give lots of aid just to entice you to attend. They meet all admitted students’ full financial need as they calculate it using their institutional formula.
Barnard also meets full financial need, using their own institutional formula. Sure, the formulas will be different, but I can’t fathom Wellesley calculating you can’t afford to pay anything AND including a Pell grant, while Barnard’s formula calculates you being able to afford over $40K a year.
Wellesley is a fabulous school (my D is an alum) but I’m concerned they made an error. Based on your FAFSA EFC (which I understand is a different formula) Wellesley’s offer doesn’t make sense, especially the inclusion of a Pell grant.
