Strongly recommended subject: ENG4U Alternative Offers You will receive an offer of admission to only 1 program. Your highest listed choice is considered first when you indicate more than 1 Brock program on your application. If you are not eligible for your first choice, your subsequent choices will be considered in your indicated order of preference. In most cases: If you apply to only 1 Brock program but do not qualify, you will be considered for an alternative or related program. If you apply but are not admitted to a co-op program you will automatically be considered for the regular, non-co-op program.

What it is	This program introduces you to how Earth's physical systems — climate, geology, water — interact with human society and geography. You explore environmental challenges through both natural science and social perspectives, rather than focusing on just one. It suits students curious about environmental issues from multiple angles who want hands-on experience through co-op placements.	This program lets you study pure science in one of four areas: biology, chemistry, physics, or a mix of these subjects. You'll take foundational courses in your chosen field and build toward specialized upper-year courses. It suits students who want a strong grounding in how the natural world works, whether they're planning to go further in science or use that knowledge in other directions.	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.
