Every real exam question we've found on merge sort, with a full worked answer.
AQA Paper 1
Both sittings we have full papers for include at least one short, prose-only question asking you to explain how a concept works or why it is useful, worth 3 to 4 marks, the closest this paper gets to a written-answer question.
OCR Paper 2
All three sittings we have full papers for test genuine understanding of how a sorting or searching algorithm works, worth 2 to 3 marks, though the exact skill, completing a merge sort, comparing two sorts, or tracing a binary search, varies each time.
