Retake the ACTS?

<p>I am currently a freshman at a four year college and I am looking to transfer for my sophomore year. NYU is one of my top choices and I am trying to make my application as competitive as possible.
I was wondering if I should retake my ACTs. I only scored a 27 when I was in high school. Would they accept an ACT score taken during college? Should I retake the test?</p>
