Both boards examine the same national curriculum content over three 90-minute papers worth 80 marks each, one non-calculator and two calculator. The specifications are near-identical on paper. The experience of sitting them is not.
Question style
Edexcel tends toward longer contextual set-ups, a worded scenario that has to be translated into maths before any maths happens. AQA more often asks the mathematical question directly but layers more structure into multi-part questions.
The practical consequence is that Edexcel students lose marks in the reading, and AQA students lose them in the later parts of a question after an early slip propagates.
Where students drop marks
Across our marked scripts from the last two series, the pattern is consistent.
- Edexcel Higher: ratio and proportion in context, and the wordier probability questions.
- AQA Higher: iterative and algebraic proof questions, where a correct idea is not written formally enough to score.
- Both boards: vectors, which remains the lowest-scoring topic in our data at 41% average.
Does it matter which one you practise?
Less than students think. Practising the other board's papers is useful extra material, and only the final couple of mocks need to match your actual board for style. If you are short of papers, use both.
