@blueandgreen A little late to the party, but there is no need for you to take the GED. You really should avoid that test as much as possible. There are plenty of things floating around the internet that say why the GED is such a controversial thing for homeschoolers.
Unfortunately, according to Florida homeschool law, (http://www.hslda.org/laws/analysis/florida.pdf) ( http://www.leg.state.fl.us/STATUTES/index.cfm?App_mode=Display_Statute&Search_String=&URL=1000-1099/1002/Sections/1002.41.html) you needed to notify the district. I’m no lawyer so please don’t take my advice as legal counsel. I think you should speak to your parents and your lawyer about how to proceed with this situation. (However, it looks like you would be Option 1)
In most situations, homeschoolers don’t need anything to prove to colleges however, when it comes to state law, it’s different. These laws usually coincide with graduation requirements for homeschoolers, so it’s imperative that you and your parents and your lawyer read over these laws and work out how to help you from here.
