Michael Schoch, Answers questions on Noodle
According to its Noodle profile, students at Duquesne University receive SAT scores in the following ranges:
520-610 in Math
510-600 in Reading
500-600 in Writing
For most undergraduate programs at the school, the minimum required GPA is a 3.0. Noodle reports that 60% of accepted students were in the top quarter of their class and 28% of students were in the top tenth of their class.
For more information, I recommend visiting the school's admissions FAQ, to which there is a link above. You can also call the admissions office at 412.396.6222 for more information.
