I was given a yearly time period to complete a course and finished within 3-4 months. Your assigned teacher isn't obligated to delegate you, but just like any field of learning. There're expectations and deadlines.Raymond Chan4/04/2021
My son recently completed Challenge and Change, a grade 12 social science course from overseas. His experience from registration, through to course work, exam competition and facilitating his grade to his transcript was exceptional, responsive, and professional. His teacher Mara was more engaged than many of his previous in-person teachers. Thank you!!!Jody Young3/05/2021

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 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
