Role of SAT IIs?

<p>What is the role of the SAT II in College Admissions? I mean, will it boost my probability of being admitted into a college i.e. Duke? Because I know I can get at least 700 in the math and 750 in the US history.</p>

<p>Thanks! :)</p>

<p>it depends whether the school calls them recommended or required</p>

<p>but getting high scores has never ever hurt anyone :)</p>
