Choose your Cambridge Computer Science course
IGCSE 0478 and AS & A Level 9618 need different preparation. Bring your syllabus code, examination year and a marked question so lessons follow the correct stage.
IGCSE Computer Science 0478. Connect computer systems theory with algorithms, pseudocode, trace tables and testing. Start by explaining each variable and how it changes, then write a solution you can check independently.
AS Level Computer Science 9618. Build structured theory answers and reliable problem-solving methods. Compare your algorithm with the questionβs requirements and practise explaining the purpose of each step.
A Level Computer Science 9618. Extend theory and programming practice for the full A Level. Plan, implement and test longer solutions, and review both written reasoning and practical programming weaknesses.

How Classes Run
Teaching plan
- Confirm syllabus code, examination year, level, school language, and target series before building the study plan.
- Separate theory recall, written explanation, pseudocode, and practical coding so each paper's demands are practised directly.
- Use topic tests and past-paper questions with command-word checks, mark-scheme language, and an error log.
- For A Level Paper 4, practise complete timed programs, testing evidence, debugging, and reliable file management.
- Finish with full-paper rehearsals and targeted revision based on recurring knowledge and technique gaps.
FAQ
Common questions about CAM CS
Clear answers about syllabus codes, level differences, programming languages, practical work, and how Cambridge differs from AP Computer Science A.
Is Cambridge Computer Science different from AP Computer Science A?
Yes. Cambridge combines computer systems theory, pseudocode, algorithms and programming across IGCSE, AS and A Level. AP CSA is a separate College Board course focused on a defined subset of Java and its own digital exam structure.
Which current Cambridge syllabuses are covered?
Support covers Cambridge IGCSE Computer Science 0478 for examinations in 2026-2028 and Cambridge International AS & A Level Computer Science 9618 for the 2026 and 2027-2029 syllabus cycles.
What is the difference between IGCSE, AS and A Level?
IGCSE builds the foundation in systems, algorithms, programming and logic. AS Level adds deeper theory and problem solving through Papers 1 and 2. The full A Level adds Advanced Theory and a computer-based Practical paper.
Which programming language is used?
Lessons follow the student's school and examination requirements. Cambridge 9618 practical preparation can support the approved language used by the centre, including Python, Java or Visual Basic in applicable syllabus cycles, alongside official Cambridge pseudocode.
Does Cambridge IGCSE have coursework or pre-release material?
The current 0478 syllabus is assessed through two written papers and no longer uses pre-release material. Programming understanding is tested through algorithms, pseudocode, logic and scenario-based questions.
How is A Level Paper 4 prepared?
Preparation uses timed computer-based programming tasks, file handling, validation, testing, debugging, screenshots or evidence capture, and complete solutions under examination conditions.
