About IGCSE Computer Science
IGCSE Computer Science covers how computers work and how to solve problems with them. It splits into two halves: the theory side, covering data representation, hardware, software, networks, cyber security and databases, and the practical side, where students design, write and test programs.
The three boards differ on something that matters more here than anything else. Cambridge 0478 has no on-computer exam at all. Both of its papers are written, including Paper 2, Algorithms, Programming and Logic. Edexcel 4CP0 and OxfordAQA 9210 both examine programming on a computer. Edexcel sets a 3 hour practical examination in one of three languages, Python, C# or Java. OxfordAQA sets a 2 hour on-screen exam built around a pre-released skeleton program, in C#, Python 3 or Visual Basic.
Cambridge's programming paper is answered on paper. Edexcel's and OxfordAQA's are answered at a computer. That is a real difference in the skill being tested, and it decides how we prepare a student. We work from real past papers for the route your child sits.
Who IGCSE Computer Science Is For
This course suits students who want a Computer Science grade they can rely on, whether their board examines programming on paper or on a computer.
- Year 10 and Year 11 students sitting IGCSE Computer Science this year
- Students preparing for Cambridge 0478, Edexcel 4CP0 or OxfordAQA 9210
- Students aiming for the top grades on their board's scale
- Learners who can code but lose marks writing algorithms and code by hand
- Students who need the theory side, including hardware, networks, cyber security and databases, tightened up
IGCSE Computer Science Exam Boards We Cover
This is the subject where the boards examine the practical work in completely different ways. Cambridge 0478 has no on-computer exam, and both of its papers are written, including the programming paper. Edexcel 4CP0 sets a 3 hour practical examination, and OxfordAQA 9210 sets a 2 hour on-screen exam built around a pre-released skeleton program. Cambridge grades A* to G, while the other two grade 9 to 1.
Cambridge
Cambridge IGCSE Computer Science 0478 is not tiered, and all candidates take two components, for grades A* to G. Paper 1 is Computer Systems: a 1 hour 45 minute written paper of 75 marks, worth 50% of the qualification, using short-answer and structured questions based on Topics 1 to 6. Paper 2 is Algorithms, Programming and Logic: a 1 hour 45 minute written paper of 75 marks, worth 50%, using short-answer and structured questions plus a scenario-based question, and based on Topics 7 to 10. Both papers are externally assessed, both are compulsory, and no calculators are permitted in either. So programming is examined on paper here, with no computer involved. The content runs across 10 topics in two groups. Computer systems covers data representation, data transmission, hardware, software, the internet and its uses, and automated and emerging technologies. Algorithms, programming and logic covers algorithm design and problem-solving, programming, databases, and Boolean logic.
Edexcel
Pearson Edexcel International GCSE in Computer Science 4CP0 is not tiered, and consists of two externally-assessed papers, one of which is a practical assessment carried out on a computer system using a programming language of choice. Paper 1 is Principles of Computer Science: a 2 hour examination paper worth 80 marks and 50% of the total. Paper 2 is Application of Computational Thinking: a 3 hour practical examination worth 80 marks and 50%, which primarily assesses the practical application of computational thinking, and in which a choice of three programming languages is available, Python, C# or Java. Both papers are set and marked by Pearson. The qualification is graded and certificated on a nine-grade scale from 9 to 1, where 9 is the highest grade, and individual papers are not graded. The content is organised into six topics: problem solving, programming, data, computers, communication and the internet, and the bigger picture.
OxfordAQA
OxfordAQA International GCSE Computer Science 9210 is not tiered, and is built around practical programming. Paper 1 is Programming: a 2 hour on-screen programming exam worth 80 marks and 50% of the weighting, based on a pre-released skeleton program. The skeleton program is released to centres on 1 March for the May/June examination and 1 August for the November examination, and the assessment is available in C#, Python 3 or Visual Basic. The paper has two sections: Section A tests programming concepts and some non-programming aspects of the skeleton program, and Section B contains short programming questions. Paper 2 is Concepts and principles of computer science: a 2 hour written exam worth 80 marks and 50% of the weighting, using a mixture of question types including multiple choice, short and longer answer questions. The qualification is graded on a nine-point scale, with grades 1 to 9, where 9 is the best grade. The content runs across eight areas: algorithms, programming, data representation, computer systems, computer networks, cyber security, relational databases and structured query language, and web page design.
How Centaurus Helps IGCSE Computer Science Students Excel
Exam Mode Confirmed First
Programming is written on Cambridge, and on a computer on Edexcel and OxfordAQA. We establish which before the first lesson.
On-Screen Programming Practice
Edexcel's 3 hour practical and OxfordAQA's skeleton program exam both reward working code. We practise in the language your board allows.
Handwritten Programming Technique
Cambridge's programming paper is answered on paper. We drill writing accurate algorithms and code by hand, under time.
Language Choice Handled
Edexcel offers Python, C# or Java, and OxfordAQA offers C#, Python 3 or Visual Basic. We teach in the language your child will actually sit.
Classes in Your Local Time
Live group sessions scheduled around your time zone, so no late nights or early mornings just to make a class.
24/7 Progress Reporting
Families get access to the Centaurus Academy LMS, with attendance, progress and lesson notes available to parents, students and teachers at any time.
Why Centaurus Stands Out
Choosing the right IGCSE Computer Science support makes a real difference. Here is how Centaurus Academy compares with typical online providers.

Excellent long-term experience
We have an excellent long-term experience with the academy and Sir Awais. Our three children studied with them during different periods and succeeded well. We highly recommend the academy.
Excellent academy
Centaurus Academy is truly one of the best educational institutions I've come across. The environment is nurturing, the staff are incredibly dedicated, and the quality of education is outstanding. They focus not only on academic excellence but also on character building and personal growth. The teachers are supportive and go the extra mile to ensure every student feels confident and motivated.
My child has gained confidence
I'm very satisfied with the dedication and teaching approach. My child has gained confidence and improved significantly in understanding math concepts, thanks to the teacher's clear explanations and supportive guidance.
