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.	ENG4U MCV4U MHF4 Science prerequisites (SPH4U or SBI4U) for specific disciplines are also required. SCH4U is recommended for specific disciplines.

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 is a four-year science degree focused on understanding natural systems and how human activity affects them. You study biology, chemistry, ecology, and earth science together rather than picking one specialty. It suits students who want a broad grounding in environmental problem-solving and are comfortable with lab work and field studies.	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.	You study physical sciences — chemistry, physics, geology, and environmental topics — with a focus on how they connect to human health and the living world. This stream emphasizes the intersection between earth and life sciences rather than pure physics or chemistry alone. The co-op option lets you do paid work terms at relevant employers alongside your degree. It suits students interested in environmental health, toxicology, or science careers that bridge the natural world and wellness.
