<p>How do I know which to take. I understand that I could take both, but I would like to focus my attention on one or the other to optimize score. What are some key ways to tell which test is right for me.</p>
<p>Take practice of both and see how you do. Which ever you feel more comfortable taking and do well on is the right test for you.</p>
<p>I honestly suggest taking one of both before you focus completely on one, the tests have different formats and only you will be able to tell which one you do better on!</p>
<p>For the SAT, incorrect answers subtract 1/4. For the ACT, no such penalty. I always regret not taking the ACT.</p>
