Why this matters
Failing the OSSLT doesn’t just hurt a grade — it holds up graduation. Students who fail must write again, and after two failed attempts they’re redirected to the OSSLC course.
The students who struggle aren’t struggling because they’re not smart. They’re struggling because nobody walked them through what the test actually looks like.

Who wrote this
High School Prep Academy exists because students don’t fail tests because they aren’t capable. They fail because they were moved forward without the right foundation.
This guide is what we wish every Grade 9–10 student in Ontario had access to — written the way it should be taught, not the way curriculum documents are written.
