AQA GCSE Computer Science Revision

AQA GCSE Computer Science Revision Checklist

Work through the AQA GCSE Computer Science specification from Sections 3.1 to 3.8 and identify which areas are secure, which are developing and which should become revision priorities.

AQA 85252027 specificationSections 3.1–3.8Paper 1 & Paper 2

How to use this checklist

Do not simply tick everything you recognise.

A topic is only secure if you can recall it, explain it accurately and apply it to a question without relying heavily on notes. Be realistic about your confidence so that revision time is spent where it will make the greatest difference.

Secure

I can explain and apply this without looking at my notes.

Developing

I understand most of it but still make mistakes.

Priority

I need to relearn or practise this topic.

Tip: copy this checklist into your revision notes and mark each topic as Secure, Developing or Priority.

Revision strategy

Knowing what to revise is only half the job.

Once you have identified your priority topics, use active recall, programming practice, exam-style questions and regular review rather than simply rereading notes.

A final revision check

Before an examination, ask yourself whether you can do more than recognise each topic. Can you explain it precisely, apply it to an unfamiliar scenario, trace or write code where appropriate and answer an exam-style question without notes?

I have worked through all eight specification sections.

I know which topics are my current priorities.

I regularly practise programming rather than only reading code.

I use exam-style questions throughout revision.

I review mistakes and misconceptions.

I return to previously revised topics after a few days.

I can use accurate Computer Science terminology.

I practise applying knowledge to unfamiliar scenarios.
