Congratulations since this program meets your need AND matches one of your strengths in terms of EC 's/community involvement. 
Are you all set now, or is R&B a pb ?
My EFC for 2016-2017 FAFSA is $34,053? Any advice for how to deal with these Financial Aid packages?
I’m curious as well. The numbers still don’t seem to work, in my opinion. OP, will your family be able to pay the rest?
I estimate the remaining costs to be about $12,000 ($12,000 tuition and fees minus $10,000 in PSA grant) and R&B at about $13,000 minus $2500 stipend. Can your family pay that?
And with the time commitment of the PSA program paired with adjustment to college and honors courses, make sure you don’t take on too many hours of work. Work this summer if possible to have a cushion.
