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.	This program combines arts courses — drawn from fields like English, history, economics, and creative writing — with business studies to prepare you for careers that value both analytical and communication skills. The co-op option lets you alternate study terms with paid work placements at real companies, giving you experience before you graduate. It suits students who want a broader education than straight business but need practical skills for the job market.

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.
