Army/Navy ROTC

I’m a junior in high school and will begin the application process very soon for the army and navy ROTC programs. Currently I have a 3.5 unweighted GPA and I’m taking many honors classes. I’m projecting that I’ll score at least a 30 in the act in the spring as I have taken many seminars, classes, and full practice test on it. I was wondering what my chances would be of being selected. The college of my choice would be University of Mizzouri, or mizzou, and I plan to pursue and engineering degree.
