I would try this. Or why not go to school part time?
It may take you another semester or two but you would still get the degree. Youre making good money and in the big scheme of things whats an extra year in school? Then once you get your BS your work may pay or at least help pay for your masters. That seems like a pretty good idea to me. Is there any reason youre in a hurry to get your BS and wouldnt wanna go this route?
