Best books for AP and SAT subject test for US History?

<p>I have asked this on the Parents of 2016 thread also, so I apologize for the redundancy, however, when I search for the answer all I can find are answers that are a few years old. So what are the best books for the APUSH and SAT US History Subject tests? S plans on taking the SAT in May right after the AP test, as recommended by others on CC. </p>
