Telephone: 01792 890700 (Gorseinon)


During year 1 students study the basic principles of cell biology, biochemistry and genetics. This enables progression to study the circulatory and respiratory systems, evolution and nutrition in term 2.   
In year 2 human biology topics such as the kidney, the nervous system and reproduction are covered alongside topics such as ecology, plant reproduction, microbiology and applications of genetics. 

Key information

  • A minimum of seven GCSEs at grades A*-C 
  • Including Mathematics/Numeracy (Higher Tier), English Language, and Double or Triple Science at grade B or above 

Hands-on practical work is carried out throughout the course in well-equipped laboratories. This allows students to improve practical and data analysis skills which are examined at the end of year 2. In the summer term, the A2 course begins with the focus on ecology giving students a chance to participate in field work. Students are taught by two members of staff.  

Two exams at the end of year 1 lead to an AS qualification (40% of A level marks) 

Four exams in Year 2 (60% of A level marks) lead to the full A level qualification. 

Many students require A level Biology for entry into medicine, dentistry and veterinary science. 

Other degree courses include biology, zoology, marine sciences, biochemistry and also other health-related subjects such as pharmacy, biomedical sciences, radiography, optometry and nursing. 

Biological science degrees can lead to a career in research, genetics, forensics and public health. There are also many environmental sciences degree courses on offer. Some students combine biology with other subjects in order to study psychology, law or journalism. 

Students are expected to participate in field work which involves studying several habitats on the Gower Peninsular and an opportunity to consider management and conservation. Each year, students are given the opportunity in Years 1 and 2 to enter the British Biology Olympiad with many achieving distinctions in these internationally recognized events. Outside speakers on topics in biology and medicine give a broader knowledge of the subject.
