As nofodad said though, make sure you are taking care of business before you pour a ton of time into something that will mean nothing the day you graduate.

Just be careful freshman year, trying to take on everything thinking you can handle it. Believe, it happened to me.
I took on an extra class, which coming in to college, I thought wouldn't be a big deal. ... how wrong was I. And because of it, it tanked my GPA a bit. That's another thing; it's much harder to dig yourself out of a hole, than to dig it.
It's hard to be able to understand this until you get to college in the fall. Trust me, it's nothing like high school. Now you have to focus on getting the good grades that will get you your job (Army or civilian), maintaining your fitness, etc. And then there's the social life: parties, opposite gender, campus activities, and anything and everything else in between.
Don't put all your money into one pot. Basically, don't just tunnel vision on RC. That's great that you want to do it, but remember you can only do RC if you have good grades. And that goes to for applying for an on-campus scholarship. If you don't have the grades, you're not getting a scholarship.
You're about to start Army during a time of downsizing. That means less funding, less funding = less scholarships. There's another thread on here that discusses cutting pay for CULP deployment. And who knows what will take a hit next, could very well be stipend money for all we know.
Grades play a significant role for your Battalion ranking (called the Order of Merit List, OML). It's weighted (at least up to last year) at 40% of your OML.
So if you don't have the grades, say good bye to Airborne, Air Assault, and all the other gee-whiz summer training opportunities out there.
But hey, good luck at Minnesota this fall. You're going to love ROTC, regardless if you do RC. Show up with a smile on your face, motivation, and willingness to learn and you'll do great.
