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.	A four-year honours degree in pure and applied mathematics, with a focus on both theoretical problem-solving and statistical analysis. Unlike a general math degree, this program runs deeper into advanced theory and proof-based courses. It suits students who enjoy abstract thinking and want to build strong mathematical foundations for graduate study, research, or technical roles in finance, engineering, or data science.	A Bachelor of Arts and Sciences lets you combine study in both humanities and natural sciences within one degree. Unlike most programs that require you to choose either arts or sciences, this one lets you take courses across both — for instance, pairing creative writing with chemistry, or anthropology with animal science. It suits people who are curious across multiple disciplines and want flexibility rather than specializing narrowly from the start.
