What it is	This program covers the science of how the human body works and how health systems use technology and data. Unlike a pre-med program, it does not guarantee entry into medical school and instead prepares you for careers in health research, data analysis, or public health. It suits students who are strong in science and math but want flexibility to explore health fields beyond clinical practice.	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	Medical Sciences is a four-year undergraduate program where you study human biology, chemistry, and related sciences to prepare for health professions or medical research. Unlike a general science degree, it focuses specifically on the foundational knowledge needed for medicine, dentistry, pharmacy, or graduate health programs. The program includes optional co-op work terms, letting you gain hands-on experience in labs, hospitals, or health settings alongside your coursework. It suits students drawn to understanding how the human body works and considering careers in health care or biomedical fields.
