Not if he flunks out because he cant handle the academic rigor of the stem heavy coursework at USAFA. Respectfully, an 1120 SAT score calls into question a student's ability to succeed. It reflects a lack of understanding of the fundamentals of algebra and geometry, and the English language. Mastery of those areas is necessary to succeed in higher levels of math and science. The fact that you have taken the SAT several times already, and prepared using Khan Academy and tutors, and keep scoring at or below an 1120, reinforces that this is your score and where you compare to your peers. As others have said, consider ROTC, or attacking this from the enlisted ranks.
Has the academy opened the main application for you yet? You previously indicated they hadn't. If that is still the case, you have a definitive answer. There is zero chance of acceptance if USAFA won't even allow you access to the full application.
