What to revise

Practise input, output and storage.

Start with these questions from the input, output and storage 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 computer systems revision. Your self-reported confidence helps plan the next review; it is not an exam mark or predicted grade.
