Your chances depend heavily on other factors:
* GPA: A very high GPA (significantly above 3.5, ideally closer to 4.0) would help compensate for a lower ACT score.
* Rigor of High School Courses: Taking challenging courses (AP, IB, Honors) demonstrates academic preparedness.
* Extracurricular Activities: Strong involvement in extracurriculars, demonstrating leadership and commitment, can significantly strengthen your application.
* Essays and Letters of Recommendation: These are crucial for showcasing your personality, achievements, and potential. Exceptional essays and strong recommendations can help compensate for a lower test score.
* Unique Talents or Experiences: Do you have any unique skills, talents, or experiences that would make you a valuable addition to the University of Michigan community?
* Major: Some majors are more competitive than others.
In short, a 25 ACT score doesn't automatically disqualify you, but it significantly reduces your chances. You would need to be exceptionally strong in other areas of your application to be a competitive applicant. It's advisable to research the average ACT scores for admitted students to specific programs within the University of Michigan, as those averages can vary across different schools and majors.
