Online Prep for U.S. history

<p>Are there any good sites for u.s. history or is it advisable to buy a book?
I got the official collegeboard studyguide for u.s. & world history from the local library, but that's all they got. I'm thinking it's not enough prep for the test though, since I've never really taken u.s. history, so I'm looking for online prep sites, if there are any.
or is it just easier to buy a book?</p>

<p>if so, which one's best?</p>

<p>Doesn't Sparknotes have online prep for that?</p>

<p>Seems like they do.
Any other websites?</p>

<p>Collegeboard has some practice questions.</p>

<p>The practice questions on the collegeboard site were a joke. You should get them all right easily.</p>

<p>Okay. Thanks for the replies.</p>
