<p>If you have perfect ACT scores, why risk ruining them with not perfect SATs? If I were you, I would leave well enough (or, in this case, perfect) alone :)</p>
<p>yeah, dont bother taking anything more. even if you get a perfect sat I score its not really going to add anything to your application since you already have the perfect act which is a comparable test. and on the off chance that you are feeling like crap or something and totally mess it up then it could hurt your application.</p>
<p>I think taking the SAT would be overkill, a perfect ACT score and many perfect SAT IIs is more than enough to show your qualification from a standardized test point of view.</p>
