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	Environmental Science combines the study of living systems and Earth's physical processes — like climate, water, and soil — to understand how natural environments work and respond to human activity. Unlike a program focused only on biology or only on geology, this degree integrates both to tackle real-world environmental problems. It suits students interested in conservation, resource management, or environmental consulting who want a broad scientific foundation rather than specialization in a single discipline.	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.	A Bachelor of Science (General) lets you study science broadly across biology, chemistry, environmental science, and related fields, choosing your own mix of courses rather than specializing deeply in one area. Unlike an honours program, it gives you flexibility to explore multiple sciences without committing to a single major or meeting the tighter requirements of a specialized stream. This suits students who are curious about science in general but aren't yet sure which direction appeals to them most.
