What it is	Computer Science at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	You study how to design and build computer software and systems from the ground up, combining computer science theory with practical engineering problem-solving. This is more applied and hardware-focused than a pure computer science degree, and the co-op requirement means you alternate between classroom terms and paid work terms with employers. It suits people who want hands-on experience in real jobs while learning, and who prefer the structured engineering approach to software development.	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.
