Why take a course with OES?
1. Upgrade marks
Many Ontario high school students register with OES as they search for flexibility in their schedule in hopes of achieving a mark they desire. We offer a wide range of compulsory and elective courses for several high school grades. Additionally, we offer upgrade courses which are courses you have taken once but need to take once again in hopes or earning a higher mark. Upgrade courses have a reduced assessment workload and can be completed more quickly helping you meet your deadline.
2. Retake a Failed Course
Some students enrol with OES to earn a high school credit course in which they were previously unsuccessful. With our supportive Ontario Certified Teachers (OCT) and 24/7 online tutoring service we will do our best to help you succeed.
Students also take courses with OES to free up their timetable for the upcoming school year, to avoid timetable conflicts, or to earn a credit not available anywhere else. Learn more here.
If you’re ready to enroll into our Ontario accredited high school courses please begin by visiting our How Does it Work? page. Included in the fee are all materials, instruction by an Ontario Certified Teacher, tests, modules, simulations examinations, and access to an online tutor which is a 24/7 on-demand and completely online service.
Shazaib is a graduate of Ontario eSecondary School and current University of Waterloo Physical Sciences student who was looking to improve the grades of his previous earned credits. He was enrolled in several science and math courses through OES, including SPH4U, SBI4U, MCV4U, MHF4U. Shazaib was taking these courses in order to get a better understanding of the concepts after taking the course through a different institution and not fully grasping the concepts. He chose Ontario eSecondary School to take all four courses.

OES is a highly professional online post secondary school which enables anyone to be able to earn high school credits or even upgrade high school marks. The administration, staff and teachers are all extremely helpful and supportive. I would absolutely recommend them to anyone!!!
Thank you OES!!! 😄Linda Sirota1/09/2021
Amazing school experience where the teachers are there to help facilitate learning and excellence, not to put their students down, like many teachers do. I re-took grade 11 university functions and received a much better education and final grade than my experience in public schooling in Southern Ontario. I would highly recommend this if you are organized and can meet your own deadlines.Derek Ford12/07/2020
One of the best school and experience I had.
Easy and comfortable timeline, professional teachers and principal, they did help me a lot to pass everything and explaining everything nice and easy to me regarding my deadline. They do have a 24 hour tutors that can help you to explain at any time I like it I don’t know what to say more but it’s one of the best school.
Thank youAL obaidi12/02/2020
Ontario eSecondary School is by far the best online learning academy in Ontario. My teacher was very great as he was easily accessible, had very fast response times, and was extremely friendly. He even had the chance to do our live meeting on Thanksgiving Monday! The course content for the class I took was great, and will be very beneficial for post-secondary learning. It was amazing that they provided free online tutoring for students, that feature really stood out to me when selecting OES for this course. You will not regret taking a course here!Julia Mesburis11/08/2020

I took a high school course with his institution in order to qualify for the college program I wanted to take.
The administrative staff and instructors were all very congenial and swift in their responses. Access to tutoring is phenomenal and I have nothing but praise for my experience with this educational provider.

I completed a Grade 11 University Physics class with OES which was required for a college program that I was looking to pursue.
My experience was fantastic; the opportunity that OES gives you to learn at your own pace is really great! The tools material provided to assist you in learning are more than adequate. They provide a free online tutoring service which is extremely helpful in a pinch!
Everyone, including my teacher and the administration, was so helpful especially Mara (Program Admin)! She was always available to assist me with any questions/requests I had. Thank you OES!R_19968/24/2020
Ontario eSecondary was a great educational experience. They accommodated and helped me through every step of the way. I am very grateful and recommend enrolling in Ontario eSecondary School.Ali Raza8/19/2020
I have tried a few online schooling products, but this one has by far exceeded all my expectations. The teacher support is amazing, the communication & preparedness is incredible, there’s free 24/7 tutoring and so much more. It has been a really impactful learning experience, would recommend it to anyone, although I have been specifically taking math/science heavy courses so that is where my perspective is coming from.Isabella Grandic8/12/2020
This was my first experience with an online course and it was amazing. My teacher was very responsive and marked assignments within the day of upload. My principle was also extremely responsive and helped with any problems I had. It was an extremely streamlined and good experience with the course material and they are updating assignments to even reflect current events going on in the world. Best online school you can choose.Sherwin Shewin8/08/2020
