A Level 2026 Exam Trends: Cambridge Computer Science 9608

Cambridge International A Level Computer Science (9608) is assessed with Paper 1 (theory), Paper 2 (fundamentals of data structures and algorithms), Paper 3 (advanced theory) and Paper 4 (practical). Here are recent trends for 2026.

Paper format and structure

• 9608 structure is unchanged for 2025–2026: Paper 1 (theory: hardware, software, data, etc.), Paper 2 (data structures, algorithms), Paper 3 (further theory), Paper 4 (practical: programming project). Check the current syllabus for exact component combination.
• Theory – definitions, explanations, diagrams (e.g. logic gates, FSM); correct technical terms. Algorithms – trace, correct, write (pseudocode/code); complexity (time, space).
• Programming (Paper 4) – design, code, test, evaluate; documentation and quality of solution are assessed.

Question types and topics that keep coming up

• Hardware/Software: CPU, memory, OS, translators; binary, hex; logic gates, Boolean algebra; FSM. Units and conversions; explanation with correct terms.
• Data structures: Arrays, lists, stacks, queues, trees, graphs; operations (e.g. push, pop); trace and write algorithms. Complexity (Big O) is often tested.
• Algorithms: Search (linear, binary), sort (bubble, merge, etc.); trace (dry run); correct or write pseudocode/code. Logic (selection, iteration, recursion) must be correct.
• Networks/Security: Protocols, layers, encryption; ethics and legal. Explanation with correct terminology.
• Practical: Problem analysis, design, code (syntax as per syllabus), testing, evaluation; documentation.

Are papers getting easier or harder?

• Standards are maintained via grade boundaries. Reports cite vague definitions, trace errors, code that doesn’t match the question, complexity wrong, and units/ conversions wrong.
• No reported shift in difficulty; precision in terminology and accuracy in algorithms/code are key.

Similarity to past papers and predictability

• Format and style match past Cambridge A Level series. Past papers are a good guide to topic balance and question types.
• Topics are predictable from the syllabus; contexts (e.g. scenario) vary. Exact questions are not predictable; marking focus (correct terms, correct logic, working) is consistent.

Examiner expectations and marking

• Definitions – precise (e.g. from syllabus); explanation with correct technical terms.
• Algorithms/code – trace must match steps; correct code must solve the given problem; syntax as per syllabus (e.g. pseudocode convention).
• Calculations – working (e.g. binary/hex, complexity); units. Practical – design, code, test, evaluate; documentation. Marking consistent with past series.

Assessment style and skills in demand

• Recall (definitions, concepts), application (to scenario), algorithm (trace, write, correct), explanation with correct terminology; practical (design, code, evaluate).

Focus areas for 2026 revision

1. Definitions – learn exact terms from the syllabus (hardware, software, data, networks).
2. Data structures and algorithms – trace carefully; complexity (Big O); pseudocode/ code to syllabus.
3. Logic gates and Boolean – truth tables, expressions; FSM where on syllabus.
4. Programming (Paper 4) – design before coding; test systematically; evaluate (e.g. limitations, improvements).
5. Past papers – Paper 1, Paper 2, Paper 3 under timed conditions.
