01

Algebra

Collect like terms, expand and factorise, and solve linear equations with the balance method: whatever you do to one side, do to the other.

Start revising 02

Quadratic equations

Solve ax² + bx + c = 0 by factorising, completing the square, or the quadratic formula, and know how many roots to expect.

Start revising 03

Graphs

Plot and interpret y = mx + c, read gradient and intercept, and recognise linear, quadratic and other standard GCSE graphs.

Start revising 04

Simultaneous equations

Solve two linear equations together by elimination or substitution, and read the solution as the intersection of two lines.
