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 MHF4U 1 of ICS4U, MCV4U, MDM4U, SBI4U, SCH4U, SES4U, SPH4U Alternative Offers If you do not meet the admission requirements for your program of choice but do meet Lakehead University's general admission requirements, you will automatically be considered for an alternate program.

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.	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.	Science One is a general first-year science program that lets you explore multiple science disciplines — biology, chemistry, physics, computer science, and others — before committing to a specific major. Unlike entering directly into a single science program, you take a broader range of foundational courses to discover which field best suits you. It works well for students who are interested in science but unsure which specialization to pursue.	A Biology degree at Glendon lets you study how living things work, from cells and molecules to whole organisms and ecosystems. You'll take core biology courses and choose from specialized areas like genetics, microbiology, human biology, or biotechnology. The iBSc variant integrates bilingual (English–French) instruction throughout your degree, rather than offering biology taught only in English.
