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.	A Bachelor of Arts and Sciences lets you combine study in both humanities and natural sciences within one degree. Unlike most programs that require you to choose either arts or sciences, this one lets you take courses across both — for instance, pairing creative writing with chemistry, or anthropology with animal science. It suits people who are curious across multiple disciplines and want flexibility rather than specializing narrowly from the start.
