Science A (4405)

GCSE Science A gives students a good basic knowledge of Science by studying a single unit from each of the core sciences. Teachers can choose between two routes:

  • route 1 - three separate exams are taken in Biology, Chemistry and Physics together with a controlled assessment
  • route 2 - two combined exams plus the controlled assessment.

Choosing Science A allows subject specialists to teach the appropriate units focusing on their area of expertise, or it can be taught by an integrated Science teacher outside their specialism.

It is suitable for students of all abilities and the course encourages students to understand theoretical concepts alongside developing practical Science skills.

When combined with GCSE Additional Science, it can form the Science component of the English Baccalaureate (Ebacc) if students achieve A* to C grades in both GCSEs.

Science A forms part of AQA's flexible suite of GCSE science exams which offer teachers a variety of possibilities and combinations to help students achieve to the best of their abilities in single, double and triple Science.
