Complete WJEC GCSE Computer Science specification revision resources. Tailored syllabus coverage with topic breakdowns, quizzes, and practice questions.
Overview
WJEC GCSE Computer Science is a comprehensive qualification designed to introduce students to the fundamental principles of computer science, including computational thinking, programming, and the impact of digital technology on society. It is suitable for students who wish to develop a deep understanding of how computers work and how to create software solutions.
This qualification develops key industry skills such as problem-solving, logical reasoning, and programming in Python or other high-level languages. Employers highly value these skills as they are essential for careers in technology, engineering, and data science.
The course maps directly to real-world career paths such as software development, cybersecurity, and IT consultancy, and provides a strong foundation for further study at A-level or in vocational qualifications like BTEC Computing.
Why Choose WJEC for Computer Science?
WJEC offers a clear and structured specification that balances theoretical knowledge with practical programming skills, making it accessible for a wide range of learners.
The on-screen assessment for Unit 2 allows students to demonstrate their programming ability in a realistic environment, directly testing their coding and problem-solving skills.
WJEC provides extensive support materials, including past papers, mark schemes, and online resources, helping students and teachers prepare effectively.
Assessment & Exam Structure
The WJEC GCSE Computer Science qualification is assessed through two external examinations: Unit 1 (Understanding Computer Science) is a written exam worth 50% of the total grade, covering hardware, software, data representation, and ethical issues. Unit 2 (Computational Thinking and Programming) is an on-screen exam worth 50%, focusing on algorithms, programming constructs, and problem-solving. There is no coursework component, but students must complete a non-exam assessment (NEA) that involves a programming project, which is internally assessed and externally moderated, contributing to the practical skills element.

Top Exam Board Tips
- Ensure you can explain the 'why' behind performance improvements, not just the 'what'.
- Practice calculating data capacity requirements using different units.
- Be prepared to compare storage technologies based on specific scenarios (e.g., portability vs. speed).
- Use clear, technical terminology when describing CPU components.
- Be prepared to recommend a storage device for a specific scenario (e.g., a portable device vs. a high-capacity server)
- Use technical terminology when comparing speed, durability, and portability
- Ensure you can distinguish between the physical mechanisms of magnetic, optical, and solid-state storage
- Always show your working out for capacity calculations to gain method marks
- Ensure you know the order of magnitude for units from bit up to terabyte
- Double-check if the question asks for the answer in bits or bytes
Common Mistakes to Avoid
- Confusing the roles of primary and secondary storage
- Failing to explain the impact of performance factors (e.g., cache size) rather than just listing them
- Incorrectly calculating data capacity requirements
- Confusing RISC and CISC characteristics
- Misunderstanding the specific function of the fetch-decode-execute cycle stages
- Confusing primary storage (RAM/ROM) with secondary storage
- Failing to justify the choice of storage device for a specific scenario
- Generalizing speed or portability without considering the specific technology type
