<p>To the last question: different schools have different policies. For example, when you go to send your SAT scores to, say, Columbia University, all of the Score Choice options will be grayed out because Columbia has told College Board they require all scores to be sent.</p>
<p>Others will allow you to pick and choose which scores to send, but even most of them will encourage you to send all of them. And, really, when they say they only consider the highest scores, I’m pretty sure they mean that (why would they say so otherwise?), so don’t sweat it. </p>
<p>Besides: on the Common App, when you’re self-reporting, they only ask for the highest individual scores (eg. highest ACT Science subscore, highest SAT CR score, etc.).</p>
