Biology is a vital subject for anyone who is thinking of working in healthcare, pharmaceuticals, the food industry, environmental science and a wide range of other careers. Central Saint Michael’s OCR Biology A Level course has been developed in consultation with teachers, employers and higher education to provide students with a qualification that’s relevant to them and meets their needs. It aims to develop:

  • your essential knowledge and understanding of different areas of Biology
  • a deep appreciation of the skills, knowledge and understanding of scientific methods
  • competence and confidence in a variety of practical, mathematical and problem solving skills
  • your interest in and enthusiasm for the subject, including developing an interest in further study and careers associated with Biology
  • your understanding of how society makes decisions about scientific issues and how the sciences contribute to the success of the economy and society

 

Content overview

YEAR 1

To be awarded the OCR AS Level in Biology A you must complete both the Breadth in Biology and Depth in Biology components.

Content is in four modules, each divided into key topics:

Module 1: Development of practical skills in biology

  • Planning
  • Implementing
  • Analysis
  • Evaluation

Module 2: Foundations in biology

  • Cell structure
  • Biological molecules
  • Nucleotides and nucleic acids
  • Enzymes
  • Biological membranes
  • Cell division, cell diversity and cellular organisation

Module 3: Exchange and transport

  • Exchange surfaces
  • Transport in animals
  • Transport in plants

Module 4: Biodiversity, evolution and disease

  • Communicable diseases, disease prevention and the immune system
  • Biodiversity
  • Classification and evolution

 

YEAR 2

To be awarded the OCR A Level in Biology A you must complete all four of the Biological Processes, Biological Diversity, Unified Biology and Practical Endorsement in Biology components.

Content is in six modules, each divided into key topics:

Module 1: Development of practical skills in biology

  • Practical skills assessed in a written examination
  • Practical skills assessed in the practical endorsement

Module 2: Foundations in biology

  • Cell structure
  • Biological molecules
  • Nucleotides and nucleic acids
  • Enzymes
  • Biological membranes
  • Cell division, cell diversity and cellular organisation

Module 3: Exchange and transport

  • Exchange surfaces
  • Transport in animals
  • Transport in plants

Module 4: Biodiversity, evolution and disease

  • Communicable diseases, disease prevention and the immune system
  • Biodiversity
  • Classification and evolution

Module 5: Communication, homeostasis and energy

  • Communication and homeostasis
  • Excretion as an example of homeostatic control
  • Neuronal communication
  • Hormonal communication
  • Plant and animal responses
  • Photosynthesis
  • Respiration

Module 6: Genetics, evolution and ecosystems

  • Cellular control
  • Patterns of inheritance
  • Manipulating genomes
  • Cloning and biotechnology
  • Ecosystems
  • Populations and sustainability

You will gain practical skills throughout the course, which are assessed in the written examinations and in the practical endorsement.

Facilities

Central Saint Michael’s Sixth Form provides excellent facilities and resources to help Biology students succeed academically and prepare for university or science-based careers, including:

  • Modern Science Laboratories: Well-equipped labs designed for practical experiments such as dissections, microscopy, and genetics work. These spaces support active, hands-on learning alongside theoretical study.
  • Digital Computer Labs: These are equipped with up-to-date software to support research, data analysis, and scientific modelling, which is especially useful in Biology for understanding complex systems.
  • Interactive Learning Tools: Biology students benefit from virtual labs and online simulations that help reinforce key concepts and prepare you for assessments.
  • Group Study & Collaboration Areas: These allow for teamwork, project-based learning, and revision in a more flexible, university-style environment.
  • Access to High-Quality Lab Equipment: The college provides a wide range of resources to support Biology practicals, encouraging students to develop investigative and analytical skills.

 

All students studying A Levels should have at least five GCSEs at grade 9 – 5 in academic subjects, including English Language at grade 5. Two of these should be grade 6.

Specifically for Biology, you will need GCSE Double Science at grade 6 or above, or GCSE Biology and GCSE Chemistry at grade 6 or above, and GCSE Maths at grade 6 or above, and a total GCSE point score of 30 or more for your best five subjects.

For when you’re not studying, we offer a whole range of enrichment activities which are not only good fun but help you make friends, develop new skills and add to your CV and university applications. There are trips and visits to bring your studies to life, like performing ecology experiments in the local park, and you can get involved in sport, debating and many other activities.

Through the Student Union and our college committees, you can get involved in volunteering, enterprise, fundraising projects or the prestigious Duke of Edinburgh Award scheme. We run societies like the Medical Society for you to join and we organise events and festivals to celebrate our inclusive and diverse community. As for entertainment, we regularly host film nights and go on theatre trips to see live productions.

Assessment is via examinations: two papers in Year 1 and three papers in Year 2.

Year 1 – AS Level

Breadth in biology (01) 70 marks 1 hour 30 mins 50% weighting Assesses content from all four modules
Depth in biology (02) 70 marks 1 hour 30 mins 50% weighting Assesses content from all four modules

Both components include synoptic assessment.

Year 2 – A Level

Biological processes (01) 100 marks 2 hours 15 mins 37% weighting Assesses content from modules 1, 2, 3 and 5
Biological diversity (02) 100 marks 2 hours 15 mins 37% weighting Assesses content from modules 1, 2, 4 and 6
Unified biology (03) 70 marks 1 hour 30 mins 26% weighting Assesses content from all modules (1 to 6)
Practical endorsement in biology (04) Non-exam assessment

All components include synoptic assessment.

 

You can progress to a wide range of university undergraduate degree courses, including:

Biology, Biomedical Science, Medicine, Dentistry, Veterinary Science, Nursing, Ecology and Environmental Science.

You can also progress to apprenticeships in Biology, Biomedical, Ecology and Environmental fields.
