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.	An Honours Arts degree lets you study humanities and social sciences — literature, history, languages, creative writing, drama, economics, or anthropology — with flexibility to combine subjects. The co-op option alternates your studies with paid work terms in related fields, giving you real workplace experience alongside your degree. This suits people who want a liberal arts education but also want to test out careers and build a professional network while studying.

Same subject area and a similar published range, at a campus you have not got in the table yet.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
