US History Prep

<p>I'm taking the November test.
Is sparknotes enough to prepare me or should I read kaplan too?
I'm aiming for 750. </p>

<p>Like I'm getting about a 750 on the sparknotes test but since there aren't any college board tests I can't compare similarity of questions. I don't know if it'll be enough. Does sparknotes cover everything or should I skim another book two?</p>
