You're not stuck. You just need a different path.

The high school system wasn't built for adult learners, students who need a second shot, or ambitious students who want to accelerate. Here's who OVS is built for.

🎯

Need to upgrade your grade 12 marks?

Your university offer depends on a stronger mark in ENG4U, MHF4U, or SBI4U. Take the course again, on your schedule, with a teacher who works with you one-on-one until the mark reflects what you actually know.

🏠

Adult learner coming back?

Returning to finish your OSSD after time away? OVS is built for adult schedules. Work full-time, parent, care for family, and finish your diploma without sitting in a classroom.

Common questions before you enrol

Answers to what most students ask on their free consult.

Are OVS credits accepted by Ontario universities and colleges?

Yes. Every credit OVS offers is a Ministry of Education-inspected OSSD credit. Universities and colleges across Ontario (and internationally) accept OVS credits the same way they accept credits from any Ontario high school. Your final mark appears on your transcript with an official OVS designation.

How fast can I finish a course?

Most students complete a course in 6-10 weeks. The Ministry requires a minimum of 110 hours of course work per credit, but you can spread that across whatever timeline works for your life. Some students finish a course in under 4 weeks working full-time; others take 4-6 months at a lighter pace. There's no "class schedule" β€” you set the pace.

What if I fail? Can I retry?

You get one full course cycle. If you're struggling, your assigned teacher will work with you one-on-one before you get anywhere near a failing mark. If you do finish with a mark below what you need, we have a re-enrolment path at a reduced rate. But in 15+ years, less than 3% of students who complete an OVS course fail β€” the teacher support model is designed to prevent it.

Is there a refund policy?

Yes. Full refund within 14 days of enrolment if you haven't submitted graded work. Partial refund on a prorated basis if you withdraw between 14 days and 50% course completion. Details covered on your consult call.

Do I need to sit in front of a computer at set times?

No. There are no scheduled live classes. All materials, lessons, videos, and assignments are available in the student portal 24/7. You work when you can. Your teacher is available via message 7 days a week and responds within 4 hours during business hours.

What's included in the $599 course fee?

Everything: all course materials, textbook access (digital), video lessons, assignments, teacher support, final exam, and your official OSSD credit registered with the Ministry. No hidden fees, no upsells. If you need textbooks, materials, or lab kits, they're included.

Can I take an OVS course while I'm still in day school?

Yes. Many of our students take an OVS course during the summer, during a spare period, or in the evening while still enrolled at a day school. Your OVS credit transfers directly to your day-school transcript once you complete it.

Is this recognized by U.S. or international universities?

Yes. OSSD is one of the most widely recognized secondary school credentials internationally. U.S. universities, U.K. universities, and most international institutions accept OVS credits without additional verification. If your target university has specific credit requirements, we can help you confirm on your consult.

Take the first step. It's a 15-minute conversation.
