Overview
You did not choose Physics (9702) because you enjoy reading mark schemes for fun. You chose it because the grade matters — and past papers are where A-Level marks are actually won or lost.
Most students finish papers. Fewer students mark them properly. This guide is for the second group: you want Cambridge 9702 past papers, real mark scheme language, and a revision loop that moves your grade — not just your page count.
Who this guide is for
This section covers Who this guide is for — ranked by what Cambridge examiners return to most often in past papers.
- A-Level students sitting 9702 this series (or planning ahead)
- Anyone self-marking who keeps thinking “that’s basically right” and still drops marks
- Students using MarkScheme who want Past paper mode matched to the official scheme
What you will learn here
For Cambridge syllabus 9702, ---
- How 9702/XX papers are labelled and which components you should practise
- What point-based looks like in real examiner language
- Five repeatable mistakes — and what to do after each one
- A weekly past-paper rhythm you can run until exams
- How to mark homework that is not from a past paper
9702 at a glance
Past papers are published as 9702/XX — XX is the component number for that session (e.g. Paper 1 vs Paper 4). Download the paper and the mark scheme for the same session from Cambridge International or your school portal. Mixing sessions is how students practise the right topic with the wrong marking rules.

How Cambridge examines Physics
For Cambridge syllabus 9702, mCQ, structured AS, structured A2, and practical skills papers. Heavy on calculations, definitions, and graph interpretation.
Paper structure
Before you sit the next paper
- Check which components you are entered for (your route matters).
- Read the command words on the front — they tell you depth, not just topic.
- Note the mark tariff per question so you know when to stop and move on.
How mark schemes work for Physics
For Cambridge syllabus 9702, marks for formula, substitution, answer with unit, and sensible significant figures. Definitions must match syllabus wording.
Self-marking rule (non-negotiable)
Open the official mark scheme first, cover your answer, and award marks as if you were an examiner. Only then uncover your work. If you read the scheme after you have already convinced yourself the answer “counts”, you are training false confidence.
Five mistakes that cost marks on 9702
For Cambridge syllabus 9702, missing units or power-of-ten errors
1. Watch for this
2. Watch for this
Using wrong equation for the scenario
3. Watch for this
Weak explanations linking maths to physical meaning
If the same issue appears twice in one week of marking, it is your number-one revision target — not “bad luck” on the day.
A revision plan that uses past papers properly
Skipping step two is why students say they are “doing past papers” while grades stay flat.
- Maintain a formula sheet tied to past paper tags
- Practice Paper 4 multi-topic questions
- Mark definitions against the scheme verbatim
The rule of three (use every session)
- Attempt — timed where possible, even one heavy question counts
- Mark — line by line with the official scheme
- Rewrite — only the step or paragraph that lost marks
Suggested weekly rhythm (6–8 weeks out)
| Day | Focus |
|---|---|
| Mon | One structured question, full mark + rewrite |
| Wed | Topic drill (definitions / short calculations / essay plan) |
| Sat | Half or full component paper under time |
| Sun | Log misses in a single notebook page — one line per lost mark |
Marking questions that are not from a past paper
Homework, textbook exercises, and test-style questions still deserve examiner-style feedback. On [MarkScheme](/mark):
- Choose My question
- Select Physics (9702)
- Add the question (photo or text) and your answer
- Read feedback tied to method marks, bands, or point marks — whichever fits the question type
For real past-paper items, use Past paper mode so we can match the official mark scheme when it is in our library. Tips for phone photos: photographing handwritten answers.
Frequently asked questions
From Cambridge International’s past paper portal or your school — always pair paper + mark scheme + examiner report for the same series.
Where do I download 9702 past papers?
How strict should I be when self-marking?
Stricter than you feel is fair on the first pass. Generous marking feels good for ten minutes and expensive on results day.
Can AI replace reading the mark scheme?
AI helps as a second pair of eyes after you have tried — not as a substitute for knowing what examiners reward. AI marking guide.
How does MarkScheme differ from comparing to model answers?
Model answers show an solution. Mark schemes show what earns each mark — including partial credit you might miss.
