Grade 9 Applied and Academic Curriculum and EQAO

This week I got called into emergency supply as an EA. While I was at the school I got to sit in on a grade 9 academic math class. The teacher had been going over information for EQAO and was starting to do review packets. The first thing she told the class she wanted to start with. She talked about how it wasn't in the curriculum but that it always seemed to be on the test, maybe because the ministry expected them to remember it. I thought this was strange as I had just completed an assignment for my math ABQ course and used rates and percent ratios as a grade 9 expectation. I went home and looked at the curriculum document and was surprised to see that this expectation was only in the applied curriculum. How is this fair for students who haven't seen the material on over a year? Are there other expectations that are tested on but not in both curriculums?
