Question 1

When should I start doing AQA GCSE Computer Science past papers?

Accepted Answer

Starting topic-by-topic past-paper questions early in the course is a really effective approach, and our by-topic view makes it easy to find relevant questions as you finish each area of the spec.

We'd suggest working through questions on each topic shortly after you've studied it, using spaced retrieval to keep that knowledge fresh as the year progresses. When your school mocks come around, it's worth treating those as a chance to try a full paper and see which topics still need attention before the real thing. For the final few weeks before the exams, we'd suggest saving two or three complete papers as your most authentic practice runs, so you can build genuine confidence in your timing across both Paper 1 and Paper 2.

Question 2

How many past papers should I do?

Accepted Answer

Since 8525 is a brand-new specification with first exams in May/June 2027, there are no past papers for this exact spec yet. AQA has released sample papers, and those are worth working through carefully, as they show the question style for both Paper 1 (computational thinking and programming skills) and Paper 2 (computing concepts). Papers from the previous AQA Computer Science spec can offer some extra practice, though the content has changed, so we'd suggest cross-referencing them with our notes to check what still applies.

Rather than aiming for a fixed number, we'd suggest using every piece of official material available and supplementing it with our exam practice questions, which are mapped to the 8525 spec topics so you can target the areas where you need the most work.

Question 3

Should I do past papers under timed conditions?

Accepted Answer

Yes! Practising with papers against the clock is a highly effective preparation strategy, because it trains you to manage your time across both exams and helps the content stick in a way that passive re-reading never does.

We'd suggest building a solid base of content knowledge first using our notes and flashcards, then moving into timed practice as your confidence grows. Paper 1 lasts 2 hours and Paper 2 lasts 1 hour 45 minutes, so it's worth experiencing that pressure before the real thing. Since AQA 8525 is a new specification with first exams in 2027, you'll be working from AQA's sample papers rather than a large back-catalogue of past papers, but they're still excellent for timed practice. Our exam practice is a great stepping stone for building question-by-question confidence before you work through a full paper.

Question 4

What should I do if I get a low mark on a past paper?

Accepted Answer

Getting a low mark on a past paper is more useful than it feels, because it tells you precisely where to focus next. We'd suggest going through every question you lost marks on, checking it against the mark scheme, and then revisiting the relevant topic in our notes before trying similar questions again.

For AQA Computer Science, Paper 1 covers computational thinking and programming (including algorithms and code), while Paper 2 covers computing concepts from data representation through to ethical impacts. Pinpointing which area cost you the most marks helps you prioritise.

Our by-topic view makes it straightforward to jump back into a specific topic after a paper, and our flashcards are great for reinforcing the key definitions and terminology that appear in shorter questions. Once you've reviewed the content, our exam practice lets you test yourself again on the same topics. That cycle of test, review, and retest is the basis of spaced retrieval, a particularly well-evidenced revision strategy.

Question 5

How do I mark my own past paper using the AQA mark scheme?

Accepted Answer

The AQA mark scheme for spec 8525 is available at aqa.org.uk/8525, alongside past papers, examiner reports, and example student answers with examiner commentaries. We'd suggest completing the whole paper before opening the mark scheme, so you're genuinely testing yourself rather than checking as you go. When you do mark up, read each mark scheme point against your answer carefully and be honest with yourself: if your answer only partially matches, award partial credit rather than rounding up. The examiner reports are especially worth reading alongside the mark scheme because they spell out the most common ways students lost marks, giving you a much clearer sense of what examiners expect. Our exam practice on Cognito can also help you build familiarity with question types before you move on to full papers.
