My oldest does not wish to go, but I do have a friend whos daughter wanted to go, she studied for and got her GED at 16 and is taking college classes, they did some testing and she was able to start out where her peers would, she was however prepared to take some entry level math courses if she needed....... most of the kids I know start at a community college at around 16 ( most all colleges welcome Homeschoolers and will let them sit in on classes as well) Then when they transfer to a University they do not have to take an SAT or ACT because they only look at their previous college record.
