<p>I've been studying for the SAT subject test in USH using the AMSCO APUSH book.
There are about 70 super packed pages in the Amsco book (which btw is very dense) on
Modern American history (1980-Present) and I was wondering if it would be
necessary to study this part.</p>
<p>How much of the SAT II is on the modern era (1980-Present)?
Does anyone have the percentage breakdown?</p>
