<p>Hello,
I wanted to know, from experienced SAT2 and AP US test takers, which book/online source gives the best practice test. I do not need the best book because I am already using AMSCO, but It only has one test. Which test will accurately, predict my score. If anything, I would want it a bit harder than easier than the actual one.</p>
<p>The Official Subject Test College Board Book. Obviously.</p>
<p>Barrons. It’s ten times harder than any other practice and makes sure you know ALL of the details. Be prepared to get your ass kicked in US History. :)</p>
<p>I score 400s on their tests, but yet, score 600s on Sparknotes.</p>
