Will an IB Diploma help my low ACT score?

<p>I took the ACT and got a 27. I’m going to retake it of course because my goal is around a 32 but i was wondering if the diploma would help me. I have many extracurricular activities, a 4.0 unweighted GPA and am in the top 10% of my class. Would i have a shot at Duke?</p>
