Trang 51 Introduction
1.1 Why choose AQA for A-level Mathematics
The changes to A-level Maths qualifications represent the biggest in a generation They’ve also
given us the chance to design new qualifications, with even more opportunity for your students to
realise their potential
Maths is one of the biggest facilitating subjects and it’s essential for many higher education
courses and careers We’ve worked closely with higher education to ensure these qualifications
give your students the best possible chance to progress
A specification with freedom – assessment design that rewards
understanding
We want students to see the links between different areas of maths and to apply their maths skills
across all areas That’s why our assessment structure gives you the freedom to teach maths your
way
Consistent assessments are essential, which is why we’ve worked hard to ensure our papers are
clear and reward your students for their mathematical skills and knowledge
You can find out about all our Mathematics qualifications at aqa.org.uk/maths
