Course outcome

Achieve a Cambridge International GCSE in Computer Science (0478). A recognised Level 2 qualification that develops computational thinking and core IT skills for further study or career pathways.

Entry requirements

No specific prior qualifications are required, although familiarity with basic computing concepts helps; the course is structured to support adult learners new to programming and computing theory.

Assessment

Assessment is delivered through externally set written examinations that test your understanding of core computing principles, programming logic and problem-solving skills.

The International GCSE Computer Science course introduces essential concepts in computing, including problem-solving, programming, data representation, computer systems and the human impact of technology. You will develop logical thinking, computational approaches and practical skills that help you understand how digital systems work and how to design algorithmic solutions.

At Lifelong Learning College, this course is delivered online with flexible scheduling and structured support that complements adult learning styles. Whether you’re returning to study, preparing for higher qualifications or building confidence with core computing skills, this course equips you with foundational understanding and capability.

Throughout the course, learners explore a range of computing topics:

  • Computational Thinking: problem decomposition, pattern recognition, abstraction and algorithm design.
  • Data Representation: how data is stored, manipulated and translated in digital systems, including binary and character encoding.
  • Hardware and Software: the purpose and function of components, system architecture and how software interacts with hardware.
  • Computer Networks: network types, protocols, security concepts and internet communication.
  • Programming Concepts: variables, control structures, functions, data structures and program design.
  • Algorithms and Logic: designing, tracing and evaluating algorithms for efficiency and correctness.
  • Cybersecurity and Ethics: digital safety, privacy, responsible computing and ethical considerations in technology use.

These topics build both theoretical and practical understanding so you can apply computing skills across contexts.

This qualification is assessed through two externally examined written papers, each contributing equally to the final grade.

Paper 1: Principles of Computer Science

Weighting: 50%

Assessment Time:

2 hours

Assessment Method:

Externally set and marked written examination

Skills and Knowledge Assessed:

Understanding core computer science concepts and their use in practical, real-world contexts

Designing, analysing, adapting, and creating algorithms

Knowledge of data representation, storage methods, compression techniques, and encryption

Understanding computer hardware, software systems, networking, and cybersecurity principles

Awareness of the ethical, legal, and social implications of computing technologies

Paper 2: Application of Computational Thinking

Weighting: 50%

Assessment Time:

3 hours

Assessment Method:

Externally set and marked written examination

Skills and Knowledge Assessed:

Designing, developing, and testing computer programs using a chosen programming language such as Python, Java, or C#

Applying computational thinking strategies to analyse and solve problems

Identifying errors, debugging code, and refining algorithms

Working with data handling techniques and file operations

Using pseudocode and flowcharts to plan and represent program logic

Both examinations include a varied range of question styles, such as multiple-choice items, short-answer questions, structured tasks, and extended written responses, allowing students to demonstrate both theoretical understanding and practical application.

Assessment for International GCSE Computer Science (Cambridge 0478) is set by Cambridge International and comprises externally written examinations that combine theory and problem-solving questions. Exams test computational thinking, practical programming understanding and application of knowledge in real-world computing scenarios.

Exams can be taken online through Lifelong Learning College, as we are an approved exams centre and can support you with exam booking and arrangements. Alternatively, you may choose to sit your exams in person at an external centre, and an advisor will help you select the best format for your needs.

  • This qualification is recognised internationally and supports progression into further study, A Levels, vocational qualifications, apprenticeships or tech-related careers.
  • Computer Science builds analytical thinking, logical reasoning and problem-solving skills — abilities valued in many industries including IT, engineering, data science and business.
  • Lifelong Learning College provides structured resources, guided activities and optional tutor support to help you understand core concepts and prepare effectively for assessments.
