2.1.3 Thinking procedurally
Decompose problems, order dependent steps and design clear sub-procedures.
What to revise
Practise thinking procedurally.
Start with these questions from the thinking procedurally topic pack. In the workspace, explain each idea from memory, compare your reasoning with the feedback, then revisit the concepts that need practice.
Use the pack alongside your OCR H446 algorithms and programming revision. Your self-reported confidence helps plan the next review; it is not an exam mark or predicted grade.
