Best way to prepare for US History SATII?

<p>I'm a home schooled student looking to take a course of classes in my junior year that I can take relevant SAT subject tests in; but, I'm unsure what textbook -- or what range of textbooks -- would be best to learn the material on the SAT history subject test. Any and all recommendations as to the best way to prep for SAT subject tests as a homeschooler would be appreciated.</p>
