ROTC from out of country High school
I am in my junior year of high school in Australia and would like to do ROTC in the states (I am an American citizen). Grades are real groovy here, and I only take 6 classes throughout all of my junior and senior year, and can drop down to 5 in my senior year. Grades also are typically worse here (50% is a pass) because the content is harder, to make up for this, when applying to universities they only look at year 12 grades and it is all adjusted based on difficulty of the course. From what I understand ROTC and colleges in general in the US don't care about the difficulty of the courses just the raw grade? Should I take easier classes and drop my worst ones so as to get a higher CGPA? I very much appreciate the help.
I'm also curious regarding when I should enroll or apply, I will graduate in October of 2027 (The school year is based off the calendar year here) so do I apply for the 2028 year?
