Computational problem solving involves systematically applying computational thinking techniques to analyse real-world challenges and design efficient, automated solutions. Learners develop the ability to decompose problems, recognise patterns, abstract key details, and implement algorithms, while evaluating correctness, efficiency, and ethical implications.

Key skills and knowledge for this topic

Award credit for clear identification of sub-tasks and their logical ordering.
Expect evidence of testing with both normal and boundary input data.
Assess accuracy of complexity analysis (e.g., correct Big O classification).
Look for justified selection of data structures (arrays, lists, etc.) over alternatives.
Reward the use of truth tables to simplify or validate conditional logic.
Evaluate discussion of specific ethical frameworks (e.g., transparency, user consent).

Examiner Tips

Expert advice for maximising your marks

💡Always write pseudocode before coding to clarify your algorithmic logic.
💡When discussing complexity, explicitly state both time and space if relevant.
💡Use truth tables as a tool to debug and verify conditional expressions.
💡Structure ethical answers around recognised principles like fairness and privacy.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing abstraction (hiding detail) with decomposition (breaking down tasks).
Overlooking worst-case scenarios when analysing algorithm efficiency.
Misapplying Boolean operators (e.g., using OR when AND is needed).
Treating ethical considerations as an afterthought rather than integral to design.
