<p>My son took the SAT once; he was very close to a perfect score, but had better things to do than retake.</p>
<p>You do not want to be viewed as unable to deal with imperfection, not having a sense of “good enough/sufficient for the task at hand” (which is a common and serious problem for engineers when they later get jobs), or a “score whore,” which is on the same level as grade grubber.</p>
<p>As a silver-lining, humorous view of this, my son said that adcoms are always mentioning how they rejected many 2400s – his less-than-perfect score saved him from becoming an example for adcoms to brag about rejecting :)) </p>
