Allow 15–25 minutes with paper for working. Use “Not sure yet” freely. Try without a calculator unless your normal learning support requires one. These are selected prerequisites, not the entire grade curriculum. High-school course order varies; our grade 11 check emphasizes Algebra 2 foundations and grade 12 emphasizes precalculus/calculus foundations.
