Just how much college were you actually able to complete as an 11b 11c in the army?

You can reach your goal man. Just all depends on how you spend your down time. If you spend it boozin and chasin tail (like most grunts) then you wont get much accomplished. If you stay focused I have buddies that have earned their Masters in the Infantry. Even if your deployed you can take 2-3 classes a semester. Internet access is highly available over there and if your chain of command knows your education goals they give you ample time for college. Like I said it all depends on you and your drive to complete your goals.
