Congrats on UGA and your scholarship! I did ROTC for a year and we had two girls who were both contracted cadets and in NPC sororities. I was in the National Guard and a service sorority. I had to miss one of our biggest events because of Drill
but that is how it goes sometimes.
ROTC stuff at our school ran pretty concurrent with regular class stuff- except AM PT (and no non-military college org has anything going on at 6AM so that's never a conflict!) Military Science classes and leadership lab were all afternoon things like any other class. The STX lanes training, overnights are like once or twice a semester so you might have to miss things if they overlap with your military stuff. However there are 16 weekends in a semester so hopefully there won't be too many conflicts. My understanding is junior year is the worst, since that is when you are preparing to go to Advanced Camp. I didn't do Basic Camp because I did Basic Training so IDK how that one works.
ROTC is neat, it's like its own family organization. Most of the military stuff isn't "hard" so there's not much studying involved. Once you get to soph/junior year there is a lot of paperwork with things like Op Orders but those become routine after a while.
