What it is	An Honours Science degree lets you study a science subject deeply — biology, chemistry, physics, computer science, or another physical science — and choose your own focus within it. Unlike a general science program, an Honours degree requires a concentrated major and typically includes a research or capstone component. The co-op option means you alternate between school terms and paid work placements in science-related jobs, which suits people who want real workplace experience alongside their degree.	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	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.	Physical Sciences is a broad first-year program where you study foundational chemistry, physics, mathematics, and biology before choosing a specialization in second year. The co-op option means you alternate between study and paid work terms at companies or research labs, giving you real experience in your field. This program suits students who are strong in math and science but not yet certain which specific physical science direction — from astronomy to polymer chemistry — they want to pursue.
