Yes, it is doable. I worked full time, and managed to take two classes my first semester, and a couple of other semesters I took one class and TAed another. Plan on having it take up all of our evenings and weekends. It won't always, but often will. For a couple of classes I even had to take some vacation days to finish up a project.

So it's totally okay to just maybe take 1 class a semester?

Yes, but it all depends on your ability and capability to strain yourself beyond normal, just for the short duration compare to the benefits in the long run.
