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	You study how Earth's systems work — its atmosphere, weather, climate, oceans, geology, and space — using physics, chemistry, and math. This program lets you do paid work terms with employers alongside your courses, giving you real experience in research labs or environmental organizations. It suits people curious about how the planet functions and wanting to test their skills in the field before deciding on a career.	Earth Sciences is a study of rocks, minerals, Earth's structure, and environmental systems — how the planet works and how humans interact with it. The program includes a co-op work placement component, meaning you alternate between classroom study and paid work terms at companies or organizations in geology and environmental fields. It suits students curious about natural systems and interested in learning through hands-on experience in the workplace.	This is a four-year science degree where you specialize in one of many fields — from chemistry and physics to biology, geology, audiology, linguistics, or environmental science. The honours designation means you go deeper into your chosen subject than a general science degree would. The program includes optional co-op work terms, letting you gain paid professional experience alongside your studies, which suits students who want both classroom learning and real workplace practice in their field.	A Science Major is a four-year degree where you study one science subject deeply — such as physics, biology, geology, or environmental science — along with complementary courses in math and other sciences. It differs from a specialized honours program in that you focus on breadth within your chosen field rather than pursuing a single narrow specialization. This program suits students who want solid grounding in a science discipline without committing to professional training like engineering or medicine.
