Overview of the course

AQA Biology AS/A Level – The course takes students into the molecular detail of biological substances and processes such as Photosynthesis, how your body turns DNA code into proteins like enzymes and how these enzymes work. The course also takes a wider view of processes such as ecological development and speciation.

Assessment:

AS Assessment: Two written papers

Paper 1 – Any content from units 1-4 (75 marks)

Paper 2 – Any content from units 1-4 (75 marks)

Each 1hour and 30 minutes long and is worth 50% of the AS

 

A2 Assessment: Three written papers                                      

Paper 1—Content from Units 1-4 (91 marks) 35% of A level

Paper 2—Content from units 5-8 (91 marks) 35% of A level

Paper 3—Content from units 1-8 (78 marks) 30% of A level  

 

 

Possible Career Paths:  

Students will require this A-level for courses such as medicine and veterinary. It is also fundamental for biomedical science, forensics or pharmaceutical science. The skills obtained are extremely favourable to employers if students wish to pursue employment following A levels across a wide range of industries including animal care.
