GCSE Additional Science
Edexcel GCSE in Additional Science – 2SA01
If you’re looking to get into college or university to study science based subjects Additional Science will prove essential.
Through studying Additional Science you will learn that it is about thinking logically and being able to apply the principles you learn to everyday situations.
The Edexcel GCSE in Additional Science comprises four units:
- Unit B2
- Unit C2
- Unit P2
- Additional Science Controlled Assessment(ASCA)
Each unit is 25% of total GCSE. Candidates can be entered for Foundation (Grades C – G) or higher (A* – C) tiers
Each of the units( P2, C2 and B2) are externally assessed through a one hour, 60 mark (25%), tiered written examination containing six questions. The examination will contain a mixture of question styles, including objective questions, short answer questions and extended writing questions. These papers will only be available in June.
Practical investigations in this unit
Within this unit, students will develop an understanding of the process of scientific investigations, including that investigations:
- use hypotheses which are tested
- require assessment and management of risks
- require the collection, presentation, analysis and interpretation of primary and secondary evidence including the use of appropriate technology
- should include a review of methodology to assess fitness for purpose
- should include a review of hypotheses in the light of outcomes.
The controlled assessment task (CAT) for the GCSE in Physics will be taken from a list supplied by Edexcel which will change every year.
