We have been using K12 International Academy for 2 years now and this looks very similar, but has some language courses we might be able to use
She will probably far exceed the academic background of her peers since so much school time is wasted on adolescent angst about social standing and activities- I have a DD who is in HS and going through this
The thing to remember is making sure your teen has social outlets, like church youth group, Scouts, sports team, dance/music groups, theater groups, and volunteer work. There are active networks of homeschoolers in most areas that provide field trips and social gatherings but it can be a bit tougher for teens
One of the first, if not the first, thing I was ever told when starting to home educate was “the trick is not to get out enough, but to stay home enough” Boy was that ever true. Home educated children typically have PLENTY of real life “socialization” (put in quotes because I hate that word)
