There is a summer session requirement for all florida public schools, but it doesn’t have to be completed the first summer. FIU specifically accepted our neighbor only to start in the summer - she could not choose to start in Aug, but had to start in June just 2 weeks after her high school graduation, and she had about 4 weeks notice. Tthat was her offer. Most students from our school started in Aug, not June. Another friend started at FSU in late June, but that was her choice. (Most of the Florida schools have several summer sessions, starting as early as May 1 when most high school students are taking finals, but also have B and C sessions starting later). At UF there is a big program for spring admits and those admits have no choice to start earlier.
