JLur,
First of all congratulations, you're starting a great journey that will last 4 years and take you in many directions. Unlike the majority of the students at your school you will be living in two different worlds, College and ROTC, enjoy both of them. Just because you're in ROTC does not mean you have to sacrifice your college experience, you will learn to strike a balance.
Enjoy the "normal" college life but don't get too distracted.
I can't agree with this more.
Both my sons were in AROTC and attended the same college. Both were in a Fraternity (I admit that not all Fraternities are created equal). My older son shared an apartment for his last two years with 3 of his Fraternity friends, not ROTC cadets. My younger son was a University Senator, and was the University Inter Fraternal Council President for one year. Both were involved in Intramural sports. My point is that you can, and should, be involved in both ROTC and College, but as was stated, don't get too distracted. There will be times you just have to say no to some college activity to focus on ROTC, as you should. Just find the right balance that works for you, keep your GPA up, make the time to work out so you have a good APFT, and make sure you participate in ROTC fully.
Each year will be different, your junior year will have much more focus on ROTC getting ready for summer training and fine tuning yourself for the OML. Senior year will allow you to have a better balance and your first two years will give you a chance to explore all that is new in college life as well as start a good foundation in ROTC.
Work hard, manage your time, and you'll have the benefits of all the college can offer.
