A good friend of mine has an online course for AP US History for home schoolers. I attended Patrick Henry College with Daniel Burns and can assure you that he has an excellent grasp on US History. If you are a home schooling parent and you are interested in having your kids pass an AP US history course I can assure you that you would be very pleased with this course. For that matter, Daniel Burns is also a missionary. By taking this course you are helping support his work in Mexico. You can sign up here.
