What it is	You study science and business together in one program, combining technical subjects like chemistry or biology with courses in marketing, entrepreneurship, and business strategy. Unlike a regular science degree with a business minor added on, this program integrates both throughout, so you learn how science discoveries become commercial products. The co-op option lets you alternate school terms with paid work placements. This suits students who want a science background but also care about bringing ideas to market or running a company.	You study psychology combined with applied health sciences — how human behaviour, biology, and social factors shape health and illness. Unlike a straight psychology program, this stream emphasizes practical health applications and the ability to work across healthcare and social systems. The co-op option lets you work in healthcare settings, clinics, or community agencies while studying. It suits students interested in both understanding the mind and applying that knowledge to real health problems.	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.
