Almost certainly. And it definitely will not hurt.
Applying for an ROTC scholarship shows that you are very interested in a military career, while not doing so puts that issue in doubt. I frankly never understand why somebody applies for the academy but does not apply for an ROTC scholarship.
Plan to take both the SAT and ACT – twice each! People often improve significantly the second time around. You appear to be a junior. Definitely need to have SAT and ACT scheduled at this point.
