Poll: what is your highest Nursing degree

I am a nurse via a diploma program; I also attended a university for ~ 3 semesters; I have taken LOTS Community College courses--equivalent to an Assoc Degree, not in nursing--and, when I was an Infection Control Nurse, a graduate level 4 quarter Epidemiology course that included a research project and paper.
I never know how to answer this question. I don't seem to fit into any of the categories.

The three major educational paths to registered nursing are a bachelor's degree, an associate degree, and a diploma from an approved nursing program. Nurses most commonly enter the occupation by completing an associate degree or bachelor's degree program. Individuals then must complete a national licensing examination in order to obtain a nursing license. Further training or education can qualify nurses to work in specialty areas, and may help improve advancement opportunities.
