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 the science of living systems — cells, organisms, genetics, and disease — with flexible depth depending on which specialization you choose. The co-op option lets you alternate between classroom semesters and paid work terms at research labs, hospitals, or biotech companies, building real experience alongside your degree. This stream suits students drawn to biology and chemistry who want either a traditional path or the chance to test careers in health and life sciences before graduating.	Life Sciences is a broad study of how living things work, from individual cells and genetics to whole organisms and ecosystems. You'll choose a focus area like microbiology, human biology, genetics, or plant science, and take courses across biology, chemistry, and related fields. The co-op option lets you alternate study terms with paid work placements in research labs, hospitals, or biotech companies, giving you real experience alongside your degree.	You study the structure and function of living organisms, from cells and molecules to whole organisms and ecosystems. The BA and BSc differ mainly in depth: the BSc requires more chemistry and physics alongside biology, preparing you for research or graduate study, while the BA offers more flexibility to combine biology with other subjects. The co-op option lets you work in labs, hospitals, or biotech companies between study terms. This program suits students curious about how life works who want hands-on experience before deciding on a career direction.
