What you will learn
-
Unit 1 - Biological molecules
This topic introduces the chemicals of life: the organic and inorganic molecules and ions that are fundamental to the structure and physiology of living organisms. It considers the role of monomers in the synthesis of polymers and how the structure and properties of these relate to their functions. The practical investigation of enzyme action develops an understanding of the scientific method.
-
Unit 2 - Cells, viruses & reproduction
This topic considers the ultrastructure of prokaryotes, eukaryotes and viruses. Details of the types of nuclear division are included and how these are involved in animal and plant reproduction. Microscopy and observational skills are developed through the preparation of stained plant tissue.
-
Unit 3 - Classification & biodiversity
This topic considers the evidence used in developing models for the classification of organisms. It also considers the limitations of these models. The topic includes the principles underlying natural selection and how this can lead to speciation.
-
Unit 4 - Exchange & transport
This topic considers the requirements for cell transport mechanisms and mass flow systems in organisms. The roles of the components of the mammalian circulatory system and the vascular system in plants are studied. Practical skills are developed by investigating factors that affect membrane permeability and water potential of plant tissues.
-
Unit 5 - Energy for biological processes
This topic builds on knowledge of carbohydrates and enzymes. It considers the energy sources in living organisms and how energy transfers occur. Details of the stages in respiration and photosynthesis, the roles of co-enzymes and electrons along with the uses of intermediates are included. Practical skills are developed in the investigations of photosynthetic pigments and the factors that affect respiration rates and photosynthesis.
-
Unit 6 - Microbiology & pathogens
This topic builds on knowledge of prokaryotes, eukaryotes, viruses and transport systems. It considers how some microorganisms act as pathogens. Details of how the human body responds to infection are included. The social, economic and ethical implications of the methods of treatment and control of the spread of infection are discussed. Microbial techniques are used in the isolation of bacteria and the investigation of the factors that affect their rate of growth.
-
This topic builds on the knowledge of nucleic acids and proteins and how they are involved in gene expression. It also considers epigenetics, the use of stem cells, and how these are contributing to medical advances. Finally, it discusses the ethical implications of the use of gene technology in scientific developments.
-
Unit 8 - Origins of genetic variation
This topic builds on the knowledge of meiosis and natural selection. It considers the dihybrid inheritance of alleles and genes, studying the inheritance of unlinked and linked genes. The effect of selection pressures on the allele frequencies in gene pools and their impact on speciation are discussed.
-
This topic builds on knowledge of transport mechanisms and considers the processes of chemical and nervous coordination. Details of the role of plant growth substances and hormonal control in mammals are included. Osmoregulation in mammals adapted to dry environments is considered. Details of the effect of drugs on the transmission of nerve impulses are studied. Practical skills are developed in the investigation of the effect of gibberellin on germination.
-
This topic considers the interactions between the organisms and the environment within an ecosystem. It includes details of how biotic and abiotic factors are involved in the development of ecosystems over time. Human influences on ecosystems and the need for conservation are also discussed.

Course Outcome
Upon successfully passing your exams, you will receive an A-level in Biology (9BI0), issued by the Edexcel exam board. Your certificate is identical to those issued to students at any other school or college, and can help you to progress onto a university degree and from there, a career in environmental management, conservation, health, and more.
We have a 97% pass rate, so you can be sure that Oxbridge and our leading team of tutors will take care of you expertly.
How is this course assessed or examined?
-
- Paper 1: Advanced Biochemistry, Microbiology and Genetics (1 hour 45 mins written exam, 30% of the qualification)
- Paper 2: Advanced Physiology, Evolution and Ecology (1 hour 45 mins written exam, 30% of the qualification)
- Paper 3: General and Practical Principles in Biology (2 hours 30 mins written exam, 40% of the qualification)
These exams contain a mixture of short and long answer questions and extended response questions.
Optional practical endorsement
Are you thinking about going into Veterinary Science or Medicine? You will need to consider the practical endorsement, as most of these courses will likely require it. Oxbridge provides this service.

Entry requirements
It is strongly recommended that learners who enrol on this course have a GCSE or equivalent in Biology (minimum grade 5-6 / grade B) and chemistry (minimum grade 4 / grade C) OR Double or Triple Science (minimum grade 5-6 / grade B) and Maths (minimum grade 4 / grade C). This course is a difficulty level three: the equivalent difficulty of an A-level or BTEC, usually suitable for most learners of all ages
Who is this course for?
This course is perfect for anyone looking to turn an interest in the natural world into a career. You might have taken a previous biology course and now feel ready to take the next step towards working in environmental management or conservation.
You can use this course to get onto a particular university degree. A-levels are worth up to 56 UCAS points, so getting a good mark in A-level Biology can put you in a great position to get a place on your first-choice degree. Because the course is delivered online, you can fit study around your other commitments from wherever you work best.
How long will it take to complete?
The course takes between one and two years to complete. Fast-track options are available. You’ll also have a personal tutor to help you stay on track and access past papers and other revision tools.
Where will my exam take place?
As an Oxbridge student, you will be guaranteed access to one of our exam centres located across the country. You may also want to consider taking a Practical Endorsement to apply the theoretical knowledge you’ll gain from studying our online A-level Biology course in a practical, lab-based setting, though this is completely optional.
