AS and A-level Chemistry (7404, 7405)

A-level Chemistry is a rigorous, challenging and ultimately rewarding course that develops students' scientific skills and knowledge.

There are six units in the full A-level – three at AS and three at A2. Four of the units are assessed by exam. The remaining two units are internal assessments of investigative and practical skills. There are two routes for internal assessment: teacher-marked or AQA-marked. This provides flexibility to meet the needs of schools and colleges and their students.

Following on from GCSE Science or Chemistry, this specification offers teachers and students freedom, creativity and the opportunity for independent progression in Science.

A-level consultations have been launched. Find out what this means for your subject on our Changes to A-levels page.
