Higher is Foundation plus a layer on top, not a different course.
The Department for Education sets one list of GCSE maths content and prints it in three styles. Standard type is for everyone. Underlined content is assessed for all students. Bold content is assessed only for "the more highly attaining students", which in practice means the Higher papers.
So a Higher student meets every Foundation topic too, and the shared middle is where grades 4 and 5 live on both tiers. What changes is the share of the paper. On Edexcel's Foundation tier, number and ratio take 22 to 28% each; on Higher, algebra rises to 27 to 33% and number drops to 12 to 18%. Higher papers also give more marks to reasoning and problem solving and fewer to routine methods.
Examples of Higher-only content
- Solving quadratics by completing the square and with the quadratic formula
- Finding approximate solutions by iteration
- The sine rule, the cosine rule and ½ab sin C for the area of a triangle
- Proving the circle theorems; the equation of a circle and of a tangent to it
- Inverse and composite functions; algebraic fractions
- Rationalising denominators; upper and lower bounds
- Conditional probability from tree diagrams, two-way tables and Venn diagrams
All printed in bold in the DfE subject content.
