Going back to school for Graphic Design with BFA in Sculpture?

I've had my BFA in sculpture for a few years now, and I have been feeling that without a strong base in graphic arts and the programs that go along with it, I am falling behind my peers. It also is quite difficult to get a steady job with just sculpture unfortunately.

My question really is:

Would it be worth it to pursue an additional concentration in Graphic Design to complement my current degree, or am I better off trying to learn on my own? I do best in a classroom setting where I can ask questions, but could make an online program work if necessary. And if I go back to school, would the coursework at a community College be enough, or should I pursue full university engagement?
