<p>Have you taken enough practice ACTs that you know it is worth your while to sit for the ACT?</p>
<p>That is a great SAT CR score. Math has a really harsh curve so I would guess a 690 represented either four or five incorrect. If you do not have time to dedicate to math practice this spring, plan to retake the SAT in Oct after completing every math practice test you can lay your hands on. </p>
<p>Colleges commonly superscore the SAT so I would not worry tremendously about a dip in your CR score. Focus on math late this summer, but then also take full-length practice tests on the weekends prior to the Oct SAT. Taking the full test will get your mind back in the groove for all sections. Good luck!</p>
