What it is	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.	Science One is a general first-year science program that lets you explore multiple science disciplines — biology, chemistry, physics, computer science, and others — before committing to a specific major. Unlike entering directly into a single science program, you take a broader range of foundational courses to discover which field best suits you. It works well for students who are interested in science but unsure which specialization to pursue.	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.	You study how the mind and body work together, and how social and environmental factors shape health. This program pairs psychology courses with practical training in areas like human biology, health policy, and social work. The co-op option lets you do paid work terms at healthcare or research settings alongside your studies. It suits people curious about mental health, public health, or how systems support people's wellbeing.
