GCSE Biology Course

Exam board: WJEC
Exam code: 3400QS

Studying GCSE Biology provides the foundations for understanding the material world. Scientific understanding is changing our lives and is vital to the world’s future prosperity, and all learners should be taught essential aspects of the knowledge, methods, processes and uses of science. Biology is a useful stepping-stone towards a variety of careers including medicine, veterinary science, physiotherapy or other biological disciplines. However, many study biology because they enjoy the subject and then pursue careers in other areas. Biology is about being curious and imaginative. It involves practical work including use of the microscope, microbiology and working with enzymes.

Biology is an extremely popular Science subject at GCSE level. It is an important source of knowledge and training for those whose Science schooling will end at this level and additionally, it is a firm basis for students wishing to continue with a scientific career.

They should be helped to appreciate how the complex and diverse phenomena of the natural world can be described in terms of a small number of key ideas relating to the sciences which are both inter-linked, and are of universal application.

These key ideas include:

  • the use of conceptual models and theories to make sense of the observed diversity of natural phenomena
  • the assumption that every effect has one or more cause
  • that change is driven by differences between different objects and systems when they interact
  • that many such interactions occur over a distance without direct contact
  • that science progresses through a cycle of hypothesis, practical experimentation, observation, theory development and review
  • that quantitative analysis is a central element both of many theories and of scientific methods of inquiry.



Written examination: 1 hour 45 minutes 45% of qualification

  • 2.1 Classification and biodiversity
  • 2.2 Cell division and stem cells
  • 2.3 DNA and inheritance
  • 2.4 Variation and evolution
  • 2.5 Response and regulation

10% of qualification

Each task comprises two sections:

Section A – Obtaining results (6 marks)

Learners will be permitted to work in groups of no more than three, to obtain results from a given experimental method. This will be carried out under a limited level of control i.e. learners may work with others to obtain results but they must provide their own responses to the questions set. Teacher assistance should not normally be required, but may be given if equipment failure occurs. Section A will be completed in one session of 60 minutes duration.

Section B – Analysing and evaluating results (24 marks)

Learners will be assessed on their ability to analyse and evaluate the data obtained in section A. They will require access to their section A assessment in order to complete this. Section B will be carried out under a high level of control i.e. learners must work individually. This section is to be completed with no teacher feedback or assistance allowed and under formal supervision. Section B will be completed in one session of 60 minutes duration


This is a unitised qualification which allows for an element of staged assessment

There are two tiers of entry available for this qualification: Higher Tier (Grades A* – D)

Foundation Tier (Grades C – G). Unit 3 (practical assessment) is untiered.

In most cases, we would expect candidates to be assessed within the same tier. Exceptionally, it may be appropriate to enter some candidates for a combination of higher and foundation tier units.

Unit 1: Cells, Organ Systems and Ecosystems (Higher Tier) – 3400UA

Unit 2: Variation, Homeostasis and Micro-organisms (Higher Tier) – 3400UB

Unit 3: Practical Assessment – 3400U3

Access Arrangements

Access Arrangements allow candidates/learners with special educational needs, disabilities or temporary injuries to access the assessment without changing the demands of the assessment.
For example, readers, scribes and Braille question papers. In this way, Awarding Bodies will comply with the duty of the Equality Act 2010 to make ‘reasonable adjustments’.

We can arrange access arrangements and assess you with our special assessor.  The deadline for application to the exam board is the February of the year the learner sits exams.
