Sophomore Transfer

I am looking to transfer from FIU to FSU in the fall of 2017. I am currently a freshman and am working as hard as possible to do good on all my classes for the next 2 semesters. My high school GPA was a 3.2 but my senior year grades were almost all A’s (freshman, sophomore & junior year were not so good). My SAT score was 1650 (old SAT). What are my chances and what else can I do to improve chances of acceptance? Is it better to apply for Summer or Fall term?
