- Students heading to college programs in geological, environmental or resource technology, or careers in mining and resource industries
- Students who want a Grade 12 university science that draws on biology, chemistry, physics and mathematics
- Students who need a senior science credit to complete the OSSD
- Students who want to add a Grade 12 university course to their timetable or admission average
- Homeschooled students, student-athletes and international students who need a flexible schedule

Official Ontario course description
Earth and Space Science, Grade 12, University (SES4U)
This course develops students’ understanding of Earth and its place in the universe. Students will investigate the properties of and forces in the universe and solar system and analyse techniques scientists use to generate knowledge about them. Students will closely examine the materials of Earth, its internal and surficial processes, and its geological history, and will learn how Earth’s systems interact and how they have changed over time. Throughout the course, students will learn how these forces, processes, and materials affect their daily lives. The course draws on biology, chemistry, physics, and mathematics in its consideration of geological and astronomical processes that can be observed directly or inferred from other evidence.
Prerequisite: Grade 10 Science, Academic

SES4U frequently asked questions
What is the prerequisite for SES4U?
The Ontario prerequisite for SES4U is SNC2D, Grade 10 Science, Academic.
Do I need a Grade 11 science before SES4U?
No. SES4U requires only SNC2D, Grade 10 Science, Academic, so it can be taken without a Grade 11 science course.
Does SES4U count as a Grade 12 university course?
Yes. SES4U is a Grade 12 University Preparation course, and many universities accept it toward admission averages. Check the admission requirements for each program you are applying to.
How long does SES4U take online?
The course has 110 hours of lessons. You have 4 months from enrollment, and extensions are available up to 12 months in total. Many students finish sooner because the course is self-paced.
Will my SES4U mark be accepted?
Yes. Aubrey Academy is Ministry-inspected, and we submit your final grade directly to OUAC and send your report card to your home school.
I already took SES4U. Can I raise my mark?
Yes. Our Mark Upgrade option builds on the work you already completed instead of retaking the full course.
