What the Grade 1 tests cover
Every Grade 1 test has 50 questions drawn from all 12 modules, so it covers the whole year, the way end-of-year tests do. It mixes three kinds of questions — solve it, word problems, and check the thinking — at easy, medium and harder levels. Each of the 12 tests uses different questions, and the parent report shows the score for every module and skill.
