<p>by taking the best scores from different test dates</p>
<p>bump .</p>
<p>I know that USC does this. I would imagine it would depend on the individual school.</p>
<p>SAT: majority of colleges take highest subscores from multiple tests, minority use only that test with highest composite</p>
<p>ACT: majority of colleges use only that test with the highest composite, minority use highest subscores from multiple tests.</p>
<p>Majority of colleges still ignore the writing section of either test.</p>
<p>A small minority actually use only the math and english score if you submit the ACT and ignore composite, reading, and science (two I am aware of: Rose-Hulman and Gtech)</p>
