UF is probably a reach with those numbers, other than the weighted GPA. Same with FSU, UCF or USF. Getting the test scores up will obviously help.

Getting an AA is definitely a good idea. It will probably make it MUCH easier to get in, provided you finish the required prerequisite courses for your intended major.
After you’ve graduated from a 4-year school, no one will care that you were an AA transfer.
