What are the minimum requirements for ACT at Duke University?

Duke University doesn't publish minimum ACT scores. They are a highly selective university, and while they don't have a cutoff, applicants with scores significantly below the 75th percentile are at a considerable disadvantage. Their admitted students typically have composite ACT scores well above 30. Therefore, while there's no official minimum, aiming for a score substantially higher than a 30 is essential for a competitive application.
