@renaissancedad - wow! If Duke’s middle 50% has an ACT range of 31-35, does that mean (per convention) that the top 25% of admitted applicants have a 36 ACT? That would mean 697 students out of 2790 admitted students in class of 2019 will have a perfect ACT score (http://admissions.duke.edu/images/uploads/process/DukeClass2019Profile.pdf). According to Prepscholar, 1407 got a perfect ACT score(http://blog.prepscholar.com/how-many-people-get-a-34-35-36-on-the-act-score-breakdown), and more half of these students applied and were admitted to Duke?
