I wanted to post this for other people who end up in my position... When I was 5 mo. old I had a kidney taken out, I haven't had any problems concerning having one kidney before. Turns out having one Kidney disqualifies you from enlistment or from going to any academy. I couldn't find any info on this online so for people in my position: No matter how good your grades are and how passionate you are there is no way around this.
