-
- Fractions: fraction of an amount; use of the four rules.
- Powers and roots: HCF, LCM, surds.
- Set language and notation: complete a Venn diagram.
- Percentages: reverse percentage; compound interest; percentage of an amount.
- Ratio and proportion: divide a quantity into given ratios.
- Standard form: conversion.
- Other: bounds.
Algebra:
-
- Manipulation: expansion of brackets; indices; factorisation; algebraic fractions; completing the square; subject of a formula; indices; algebraic fractions and formulae.
- Equations: linear equations; quadratic equations; simultaneous equations, linear and quadratic; simultaneous equations, linear.
- Proportion: direct proportion.
- Inequalities: graphical representation; quadratic inequality.
Sequences, Functions and Graphs:
-
- Sequences: nth term of an arithmetic sequence; sum of arithmetic series.
- Functions: inverse functions; transformation of functions.
- Graphs: graphs of lines; parallel and perpendicular lines; transformations of functions; graphs of trigonometric functions.
- Calculus: linear kinematics.
Geometry and Trigonometry:
-
- Angles and shapes: angles in polygons; geometric reasoning.
