What it is	This program lets you study science broadly — chemistry, physics, biology, materials science, and related fields — at university level. Unlike a specialized honours program in a single science, this one gives you flexibility to explore multiple areas before focusing deeper. The co-op option lets you alternate study terms with paid work in science-related industries. It suits students who are strong in math and sciences but not yet sure which direction to specialize in, or who want practical work experience alongside their degree.	International Business is a business degree that prepares you to work across borders and cultures, combining core business subjects like accounting, management, and marketing with a focus on global economics and international development. Unlike a general business program, it emphasizes the particular skills and knowledge needed for companies operating in multiple countries. It suits students interested in trade, global markets, or managing international teams, and who are comfortable with both quantitative and social science coursework.	You study science and business together in one program, combining technical subjects like chemistry or biology with courses in marketing, entrepreneurship, and business strategy. Unlike a regular science degree with a business minor added on, this program integrates both throughout, so you learn how science discoveries become commercial products. The co-op option lets you alternate school terms with paid work placements. This suits students who want a science background but also care about bringing ideas to market or running a company.
