Do Florida universities have to accept students with an AA degree?

No, Florida universities are not required to accept students with an AA degree. While an AA degree demonstrates college-level readiness, admission to a Florida university is a competitive process based on various factors including GPA, test scores (depending on the university's policy), application essays, and the overall strength of the applicant pool. Having an AA degree significantly improves the chances of acceptance, but it's not a guaranteed admission.
