<p>You can take the SATs as many times as you want to.</p>
<p>All your scores are reported, but most people say they will look at your highest score each section (i.e., if you get a 600/650/600 and a 500/700/610, colleges will treat your score as a 600/700/610, but will see all the scores).</p>
<p>Tests taken before 9th grade don't count for any of this though.</p>
