1. Algebra: simplifying and rearranging formulas, solving equations (including distributive and multi-step), constructing formulas, nth term of sequences, forming expressions from context. 2. Geometry: bearing calculations, enlargement and translation, measuring angles, scale drawing of nets, identifying rotational symmetry, properties of quadrilaterals and polygons. 3. Number: ratios and proportions, probability of events, fraction operations, significant figures rounding, calculator-based volume and paint coverage problems, unit conversions (e.g., mm to m). 4. Data and statistics: interpreting stem-and-leaf diagrams, median and range comparisons, identifying consistent data, average calculation and selection (mean, mode, median), survey reliability. 5. Probability and logic: spinner fairness analysis, sample space diagrams, comparing probability values, calculating missing probabilities. 6. Sets and classification: Venn diagram with rational, integer, and natural numbers, placing values based on number properties.
