Just weighing in here real quick on Geometry via home study. We opted to homeschool this year and went with Switched On Schoolhouse. We bought Geometry (about 100 bucks, though you might get for 89 dollars online at their site or even Amazon) for our 13 yo 8th grader.
We paced it out to a year long class because that's how it would have been given if we'd been able to move to a different school district last summer. Our current school district offers it as a semester class only.
I'm not a "mathy" person, so the bulk of it falls to my husband to grade her work and to explain things she might have trouble with. Had he not been a math-type of person, I would have truly hesitated.
The SOS does not have a workbook, which is a drawback. Lesson questions on a computer do OK, but really, in my hubby's opinion, you need something for reinforcement outside of a computer-based instruction. I ended up getting our state's textbook at a Goodwill for reference because sometimes the SOS wasn't crystal clear on some of the finer points.
She struggled a lot at the very beginning and required some handholding from my hubby. If we are able to move this school year, she would be able to join a class in progress and take the state test. If she were to finish it and we were unable to move, the school district we plan to move to would allow her to take the state test when it's regularly given, even if she took it at home. This would allow her to get high school credit for the class.
I hope this helps! I know you asked about other programs, but I agree with the above poster who said local support/tutoring may be necessary. I also agree with many who said to take a stand and try to get your child into the geometry if you can. My hubby told me that he learned geometry on his own in a self-paced math class and really wish it had been a real teacher teaching it. He felt it was his weakest math.
