Hi Elisabeth,
Thank you for your question about Post Secondary School and thank you for using the Ask Us service.
Depending on where you live, where you want to go to post secondary school and what you want to study admission requirements can be different from school to school. It would be best to consult with your school Student Support Services for your specific situation. If you are interested in reviewing general information about Ontario Post Secondary Schools please refer to the websites listed.
