About WGU C304 Advanced Pathophysiology
C304 is a graduate-level pathophysiology course in WGU nursing programs. It builds on undergraduate pathophysiology and focuses on complex disease processes relevant to advanced nursing practice. The OA (Objective Assessment) is challenging but passable with the right preparation.
