IGCSE Computer Science is chosen by students who enjoy logical problem-solving and are curious about how technology works, and it is a natural partner for Mathematics and Physics. In Gulf international schools it often sits alongside ICT, but it is far more about computational thinking than using software. The Cambridge 0478 course is split into computer systems, covering six theory topics, and algorithms, programming and logic, covering four practical topics.

Assessment is through two written papers of 1 hour 45 minutes and 75 marks each, worth 50% apiece, and there is no coursework. Paper 1 tests computer systems; Paper 2 tests algorithms, programming and logic, ending with a scenario question where students write a full solution in pseudocode or in Python, Visual Basic or Java. Calculators are not allowed in either paper, so number-base conversions and file-size calculations are done by hand.

The hardest parts for most students are designing algorithms from a written scenario, completing trace tables accurately, writing nested loops with arrays, and SQL queries. Theory answers lose marks when they are generic rather than linked to the context given. IGCSE Computer Science leads well into A Level Computer Science and is useful preparation for IB Computer Science, engineering and data-focused degrees, where structured problem-solving matters as much as coding.

What topics are in IGCSE Computer Science?

The full syllabus, with the spots where students most often lose marks.
  1. 1

    Data representation

    Forgetting overflow in binary addition and confusing logical with arithmetic shifts.

  2. 2

    Data transmission

    Describing packet switching without routers or reassembly, and mixing up echo checks with checksums.

  3. 3

    Hardware

    Explaining the roles of registers and buses vaguely, and confusing sensors with actuators.

  4. 4

    Software

    Listing operating system functions without explaining them, and mixing up interrupts with polling.

  5. 5

    The internet and its uses

    Explaining HTTPS, digital certificates or firewalls in generic terms.

  6. 6

    Automated and emerging technologies

    Describing robots or artificial intelligence without the specific characteristics the question asks for.

  7. 7

    Algorithm design and problem-solving

    Flowcharts with missing decision labels and trace tables with skipped steps.

  8. 8

    Programming

    Array index errors in nested loops, and procedures that do not return or output the result asked for.

  9. 9

    Databases

    Choosing an unsuitable primary key and writing SQL with the wrong syntax for conditions.

  10. 10

    Boolean logic

    Writing logic expressions that do not match the circuit drawn.

How do you get top marks in IGCSE Computer Science?

  • Learn the Cambridge pseudocode conventions thoroughly, as Paper 2 uses them in every question.

  • Before writing code for the scenario question, list the inputs, the processing required and the outputs.

  • Annotate long answers with comments so partial solutions can still earn method marks.

  • In theory questions, link every point to the scenario's context rather than giving textbook definitions.

  • Practise binary, hexadecimal and file-size calculations without a calculator under timed conditions.

  • Dry-run your algorithm with sample data before moving on, to catch off-by-one errors.

IGCSE Computer Science FAQs

How many papers are there in IGCSE Computer Science 0478?

Cambridge IGCSE Computer Science 0478 has two papers, each 1 hour 45 minutes long, worth 75 marks and 50% of the grade. Paper 1 covers computer systems and Paper 2 covers algorithms, programming and logic. There is no coursework, and calculators are not permitted in either paper.

What programming language is used in IGCSE Computer Science?

In Cambridge IGCSE Computer Science 0478, programming answers can be written in Cambridge pseudocode or in Python, Visual Basic or Java; other languages are not accepted. Students need to read and write the official pseudocode style as well. Our tutors teach Python for hands-on practice and map it to pseudocode throughout.

Is IGCSE Computer Science hard?

IGCSE Computer Science is challenging for students who have not practised programming, because Paper 2 requires writing correct algorithms under exam pressure. Students who code regularly and learn theory definitions precisely usually find it very manageable. Starting programming practice early in the course makes the biggest difference.

What is the difference between IGCSE Computer Science and ICT?

IGCSE Computer Science focuses on how computers work, algorithms and programming, while IGCSE ICT focuses on using software applications and the practical uses of technology. Computer Science suits students interested in programming, engineering or computing degrees. Schools sometimes offer both, and the choice depends on whether a student enjoys logic and coding.

Is IGCSE Computer Science the same as O Level Computer Science?

IGCSE Computer Science 0478 and O Level Computer Science 2210 have the same topics and paper format. The difference is the qualification and grading scale: IGCSE runs from A* to G, while O Level runs from A* to E. Cambridge does not allow candidates to take both in the same exam series.

How can I get an A* or a 9 in IGCSE Computer Science?

Students who achieve an A* or 9 in IGCSE Computer Science write precise, contextual theory answers and design correct algorithms confidently. Practise trace tables, SQL and full scenario questions under timed conditions, and compare your code with mark-scheme solutions. Our tutors support this practice, but we never guarantee results.
