This is where you'll build your bedrock. Foundational Mastery systematically breaks down the vast landscape of medical knowledge into manageable, digestible sections. You'll dive deep into Physiology by System, understanding how each part of the body normally functions. Then, you'll explore Pathology by System, learning the mechanisms and manifestations of disease within those systems. We also dedicate sections to Core Basic Sciences, ensuring a strong grasp of the fundamental principles underpinning all clinical practice, and crucial areas like Psychiatry, Epidemiology, Statistics, and Behavioral Sciences to round out your comprehensive understanding. This phase is all about establishing a robust and detailed knowledge base.
