From what's expected of you to what you can expect on standardized tests, here's information to help you make your way through school.
The Education Quality and Accountability Office (EQAO) runs assessment testing:
The EQAO wants you to do well on these tests. They've got tools to help you prepare for the Grade 9 math test and the Grade 10 OSSLT. You can also get tips from a brochure written for teachers called Preparing Students for the OSSLT.
If you're a Canadian adult, living in Ontario but not currently attending secondary school, you may be able to continue your studies through distance education. The Independent Learning Centre (ILC) provides a distance education program, in English and in French, for Ontario residents who want to earn secondary school diploma credits, upgrade basic skills, or study for personal development. The ILC also offers an elementary program for children temporarily living outside Canada.
A number of other distance education options are also available.
