<p>I already took the SAT and superscored a 2340 (800M, 760CR, 780W). Is it good to take both or would it just be stupid? Thanks!</p>
<p>I think your second assertion is correct 
Forget ACT, work on SAT subject tests and your GPA.
Congratulations on great SAT score. If you somehow could not get into any school, it will have nothing to with your scores.</p>
