<p>Alright, so I've acquired a copy of AMSCO and a copy of the Crash Course book. How do I use these in conjunction with each other, effectively?</p>
<p>You don’t. AMSCO will suffice. I’m assuming that you have other AP classes and exams to worry about; you don’t need both review books to get a 5 on APUSH.</p>
<p>Oh, alright. Thanks for your help.</p>
<p>Just read them and know the information. There are no secret studying techniques haha.</p>
