I would only say, take nothing for granted. After watching my son go through this process for three academies, USMA, USAFA, and USNA, and having talked to admissions officials at each Academy several times, I will say that the test scores are perhaps the most important of all the individual scoring criteria, but everything matters, and so much depends on the competition within any applicant pool you are in.
My son took the ACT, and ended with decent scores due to the superscore; m34, e31, s34, and r30, but his composite was never more than 31 on any single ACT exam. He took the ACT four times and improved his superscore each time. I would keep taking the test if you can. Every point matters.
Class, standing and CFA matter too, along with leadership and everything else. Put together the best well rounded application you can. As good as you can get, there may be someone better.
My son was admitted to USMA in January, and then to USAFA, and was placed on wait list for USNA. No harm though, as WP was his first choice, but we were still puzzled he hasn't been offered appointment to USNA. We kind of took for granted he would be, and we were wrong. Some factor, or factors, led to him not being considered to top candidate in the pools he was competing in for USNA. All you can do though is be sure you have done everything within your control to win a spot. Never assume you have got it made, based on what you have as compared to what others who have been admitted have.
