<p>^Do they? Which colleges?</p>
<p>I am aware of none that do so. The usual division is: (a) majority of colleges use your highest subscores from multiple tests to come up with your SAT score to determine admission, e.g., score 700 math/600 CR/ 650 writing on one test and 600 math/700 CR/600 writing on another and your score for admission purposes is 700 math/700 CR/650 writing; (b) large minority, including many public universities, use for admission that particular test which has the highest composite score and ignore other tests.</p>
