What it is	Biology is the study of living organisms, from cells and genes to plants and animals. This program lets you choose to add paid work terms in research labs or related industries alongside your courses, giving you real experience before you graduate. It suits students who want hands-on learning and a chance to explore career options while earning money.	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.	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.
