<p>Unfortunately, Collegeboard sends all your scores (quote from website): "All available scores will be sent, including those from previous test administrations. You cannot send only your latest or highest SAT Reasoning Test scores, or separate scores for critical reading or math or writing, or only SAT Reasoning Test or only SAT Subject Tests scores. "

<p>So, basically nothing is withheld even if you took the SAT I and want to use your ACT, colleges that require SAT II's + ACT will see your SAT I score (Collegeboard has such a black heart).</p>
