California and Florida aren’t the same system, so what California does has no impact on policies in Florida.
The only similar guarantee is that if you earn an AA degree with a 3.0 GPA, you are guaranteed admission to a public university if you meet certain criteria. The last time I saw the requirements, that included applying to 3 of the public universities and being denied by all three of them, among other things.
Priority admission does not mean guaranteed admission. Plain and simple. A 3.1 GPA may be good enough to get you accepted. It may not. Personally, I think it’s probably borderline for a limited access program at FSU. Having the AA degree does help. If you were applying to a program that wasn’t limited access, I wouldn’t even question it and would say your odds of acceptance are probably 90-95%, minimum.
