FYI - from UF’s FAQ regarding scholarships:
"Can I “stack” scholarships offered by UF with my other financial aid awards or other scholarships I’ve been offered?
It depends. The type of award will determine whether your scholarship will “stack” or will adjust that particular award.
UF’s merit-based scholarships may impact how much in loans you are eligible for, but it will not change the amount of Pell grant you are eligible for.
UF’s Presidential scholarships will “stack” on top of Bright Futures and the Benacquisto Scholarship offered by the Florida Department of Education.
UF’s out-of-state scholarships cannot be stacked with another scholarship (offered by the School of Music, for example) since both scholarships waive the same portion of non-resident tuition."
It appears to me that the Presidential Scholarships are indeed in addition to the Benaquisto.
