Retake the ACT or SAT?

<p>I took a 6 week Princeton Review Class for the SAT and took multiple practice tests and my results were:
Critical Reading 670<br>
Math 690<br>
Writing 670</p>

<p>I took the ACT after reading the Dummies guide Sparknotes but no practice tests and my results were:
Composite: 31
English: 31
Math: 32
Reading: 35
Science: 26</p>

<p>I may also have to retake the Math 2C Subject Test on one of the test days since i got a 710.
So, should i focus studying on the ACT or SAT? I might retake both, but I definitely don't have the time to STUDY for both. </p>

<p>Thanks.</p>

<p>which one are you better at? take that one...</p>
