Applying to Integrated Science
Enrollment in Integrated Science is limited. There are two ways to apply to Integrated Science:
- Directly apply to Integrated Science (YPU) as part of your OUAC application.
- Apply to one of our science programs and express your interest in Integrated Science by e-mailing isci@yorku.ca. Qualified students will be added to our candidate pool. This pool will be evaluated at the end of April.
Strong academic performance in all prerequisites is required. Your academic average should be in the mid-80s or higher to be competitive for Integrated Science. For standard high school curriculum, your average is calculated from the following courses: ENG4U; MCV4U; MHF4U; two of SBI4U, SCH4U and SPH4U; and a sixth course. For students with all three of these sciences, your top two grades will be included in the calculation.
