I agree with jsd. In the time you'd need to earn the credits for an RA associate degree you could be done with a WGU bachelor. I see you have a few plans for WGU - if you haven't already applied to them I would suggest you do and be sure you know where you stand. You can keep transferring into WGU right up until you enroll (not after enrollment)
