A 17 on the ACT (assuming you mean the ACT, not another test) is
unlikely to get you into Samford University. While Samford doesn't publish a minimum ACT score, their average ACT score for incoming freshmen is significantly higher. They are a selective university, and a competitive applicant will have a much higher ACT score, typically in the mid-20s or higher, along with strong grades, extracurricular activities, and a compelling application.
While a 17 isn't disqualifying in itself, it puts you at a considerable disadvantage. You'd need exceptionally strong performance in other areas of your application to compensate. It's advisable to explore other universities that may be a better fit for your academic profile.
