International AS and A-level Chemistry (9620)

A-level Chemistry

Give your students a broad range of experience in the three areas of physical, organic and inorganic chemistry.

Mirroring the way many universities split their content, each section begins with an overview, which puts the topic into a broader chemical context and ensures understanding of the place of each topic within the subject. These overviews encourage an overarching approach to the teaching and learning of topic areas. In addition, the latest version of this specification takes a more modular approach to physical chemistry, with units re-ordered to simplify teaching and revision.

  • Practical work is at the heart of science. We recognise this, so our specification includes ten practicals that have been designed to give students a broad range of hands-on knowledge.
  • These practical components are flexible around local access to equipment and materials, with practical knowledge assessed through the main exam papers.
  • Our papers are carefully designed to avoid cultural or linguistic bias, using the principles of Fair Assessment and the Oxford 3000 to ensure the vocabulary is as clear as possible.
  • Exam papers include a range of question styles allowing students to demonstrate scientific skills, logical thinking and depth of knowledge.

OxfordAQA provides all the resources and advice you need to teach the International AS and A-level Chemistry specification effectively.

We have too many International AS and A-level Chemistry resources to list here, so please visit our resource area for teachers to see them all, including:

  • Schemes of work to allow you to plan how to deliver the specification in a way that will best suit you and your students
  • Teaching guidance to outline clearly the scope of teaching and learning
  • Topic tests and mock exam analysers to allow you to track your students’ progress throughout the teaching year

These qualifications are modular. The full International A-level is intended to be taken over two years.

For details of the assessment for International AS and International A-level, please see pages 8 and 9 of the specification.


  • Candidates may re-sit a unit any number of times.
  • The best result for each unit will count towards the final qualification.
