There is a lot to be said about the maturity of someone taking classes at a later stage in life. I went back to get my CS degree after my time in the military. In high school I was a solid C student, in my associate degree before the military I was a B+ student, after the military I graduated Summa Cum Laude and the only two classes I didn't get an A in were classes that I missed the first two weeks of school because I was deployed with the National Guard. The self-discipline makes a huge difference.
