The Florida public university weighted GPA recalculation gives +0.5 for honors courses and +1.0 for AP, AICE, IB, and college courses. The GPAs listed on sites like the following are presumably from this recalculation.
Note that Florida public universities have a 9 credit summer session requirement (must be at a Florida public university, not transfer credit from other colleges), so that needs to be considered for financial and schedule planning.
