It didn't take very long, but less than a year of commissioning, I began my MA in International Relations. I was really shocked when I learned that the Army could offer college degrees on-post that were in a real classroom setting with real professors. It was too tempting to not at least try a course or two while working.
Funny, but I wouldn't have ever made such a move without my Battery Commander suggesting I should get my MA in the Army as soon as possible. In about a month I'll really know how tough this will be with regular classes taking up my weekends...only pre-class assignments until then.

Stick with it, it's worthwhile.
And there are probably a couple of people here on the site that can help you with IR theory ;)
