I am an enlisted Soldier and I am about to complete my Bachelors with a 3.49 GPA. Would it be beneficial to retake one class (pay 1.2K out of pocket) to get over a 3.5? Will this make any difference if I decide to go Officer or Warrant, or when I am choosing a Master's program?

I am tempted to do it just because I have come so far and I can say I got the 3.5, but I don't think it makes any difference in the long run and is only important to me.
