As far as I know, there are certain scholarships that are only eligible to EA applicants to Frost.
‘Early Action is for the most academically competitive students admitted to the freshman class. Applicants who wish to be considered for the University of Miami premier scholarships should apply Early Action and submit all required materials for both the university and the Frost School by the deadline.’
