Flieger is 100% correct. As he is practically always. It's about the "whole person". Not just act or sat scores. It's leadership, teamwork, community, gpa, sports, etc.
While I haven't had an applicant who received a perfect 36, I did have 2 who had a 35 on their acts. They were also 4.0 gpa students in the most challenging curriculum. But they didn't have many of the other things the academy was looking for in an applicant. Both got turned down to the academy. One got accepted to Georgetown and the other to Yale. Yet, you would have though either was a shoe in for the academy.
You will see some applicants who get into the academy with 32-36 act, 4.0 gpa in the IB program, but they also has 2-3 varsity sports, class officer, involved in clubs, leadership roles, etc. they were the complete package. You'll also see others with the complete package with a 3.6 gpa and 27 act scores.
The academy will take a 26 act and 3.6 gpa with a complete package of all the other leadership, sports, volunteering, etc. attributes mentioned, before the take an individual with. 36 act and 4.0 gpa and that's ALL they have.
Remember, the academy is recruiting "Future Military Leaders". They aren't recruiting future college professors, think tank scientists, and academia brainiacs. Of course, the majority of cadets happen to be some of both. The average gpa in advanced high school glasses is 3.86 gpa. Average act is 30-31. But these individuals are also highly involved in sports, clubs, social activities, leadership, teamwork, etc. best of luck.
