U.S History- general questions

<p>Hey, I'm taking the US Hist. SATII in May, and I haven't done any preparation or bought any books yet- it's been the least of my worries. </p>

<p>I have a 4.0 in AP US, but I get lazy and never read the text book, so I'm worried that I won't know a lot of facts on this test. </p>

<p>For people who have taken this before, is it hard? How much prep? (again, I know nothing about this test, including # of questions, time, etc.---nothing)</p>

<p>thanks.</p>
