Is this possible? For getting into the military academy?

Ok I'm a junior in high school right now. Im currently in independent studies because of poor choices in the past during my frist two years in high school. I only have about 37 credits so far. Yes I know it's low and regret every part of my freshman and sophomore years. I was thinking of asking my parents to get me into a military boarding school so they can help me out and also make me as a more independent person because right now I'm having everything I want and I know for a fact in the future it's going to come and bite me in the butt. My plan was getting in the military boarding school and work my butt off and hopefully get into one of the military universities once I graduate. I one day want to actually join the united states army and become the highest rank because I'll do anything to help the country I love the most and thats the united states of America. Is my plan already immpossible or can I still make a dramatic comeback?
