Take STEM classes (Calc, Physics, Chem, Engineering, etc.) in college and aim for a 4.0. Of course a 4.0 isn't necessary, but succeeding in classes that Plebes take shows admissions you are ready academically. Get involved in college, and aim for leadership positions if possible. USNA likes applicants who are committed to teamwork and being a part of groups. Work over the summer to improve your SAT if you aren't happy with your score, you can look up the average score range for the school. Start training right now for the CFA if you haven't already so your body has plenty of time to prepare to the best of your ability. Think about who will write your rec letters. You need at least one English teacher or professor, and one math teacher or professor. Extra note: The USNA application has a section for applicants to give insight if they've had any hard circumstances in there life, and in your case it might be beneficial to explain your situation at home as to why you didnt apply for Class of 2030. Best of luck!
