As a Freshman? UF accepts freshman students to the University and not to each college/program. UF doesn’t consider your major in making it’s decision.
The middle 50 percent of students admitted to the 2014 fall freshman class had the following criteria:
High School GPA of 4.1-4.5
SAT 1810-2060
ACT 27-31

As a transfer student (a junior), you have to apply to each college. Each college has it’s own requirements, including GPA requirements.
