What Is Cambridge A/AS Level Physics 9702?
Cambridge International AS & A Level Physics 9702 is the qualification awarded by Cambridge University Press & Assessment (Cambridge International) for pre-university physics study. It is taken at age 16–19 and is recognised for university entry by institutions worldwide, including Ivy League universities in the US, Russell Group universities in the UK, and universities across Europe, Australia, Canada, and New Zealand. UK NARIC has independently benchmarked Cambridge International AS & A Level as comparable to the standard of AS & A Level in the UK.
The qualification is split into two levels. AS Level (the first year) covers 11 topics and leads to the Cambridge International AS Level qualification on its own. A Level (the full two-year course) requires AS Level content plus 14 additional A2 topics, totalling 25 topic areas. Both levels assess practical skills, which carry significant mark weight across all papers. The current syllabus (Version 1, published September 2022) is valid for examination in 2025, 2026, and 2027.
Physics 9702 is available in June and November series worldwide, and also in a March series specifically for India. Students should always confirm which series and year they are preparing for, as examiner reports and grade thresholds are series-specific. Students also studying A/AS Level Chemistry or A Level Mathematics will find significant overlap in mathematical methods and practical skills. Students transitioning from IGCSE Physics should note the significant step up in mathematical rigour and the introduction of formal practical assessment.

What Is the Cambridge 9702 Physics Exam Structure?
Cambridge International AS & A Level Physics 9702 is assessed through five papers. AS Level students sit Papers 1, 2, and 3. A Level students sit all five papers. The 2026 exam series uses the same paper structure as 2025 — no significant changes to the assessment format have been published by Cambridge International for the 2025–2027 syllabus period. Students also taking A/AS Level Statistics will find the data analysis and uncertainty skills in Paper 5 have useful crossover.
| Paper | Name | Level | Format & Duration | Key Skills Tested |
|---|---|---|---|---|
| Paper 1 | Multiple Choice | AS | 40 MCQ, 1 hour 15 min | Syllabus knowledge recall and application, AS content only |
| Paper 2 | AS Level Structured Questions | AS | Structured questions, 1 hour 15 min | Written explanations, calculations, graphs; AS content only |
| Paper 3 | Advanced Practical Skills | AS | Lab-based practical, 2 hours | Hands-on experiment: data collection, analysis, error estimation; context may be outside syllabus |
| Paper 4 | A Level Structured Questions | A Level | Structured questions, 2 hours | Calculations, explanations, synoptic questions; full A Level content |
| Paper 5 | Planning, Analysis and Evaluation | A Level | Written paper, 1 hour 15 min | Q1: plan an experiment; Q2: analyse data, linearise equation, draw graph, calculate gradient/intercept, determine uncertainty; context may be outside syllabus |
The Practical Papers (Papers 3 and 5) — What Students Miss
A critical point that most students overlook: Papers 3 and 5 can include contexts that are outside the 9702 syllabus content. Cambridge International is explicit about this in the syllabus specification. Students are assessed on their practical skills — planning, measurement, analysis, uncertainty, and evaluation — not on their knowledge of the specific physics scenario used.
A student who sees an unfamiliar setup in Paper 5 and concludes they have been given wrong materials has misunderstood the paper’s design intent. The skill being tested is transferable, not topic-specific.
How Do You Score Well on Cambridge 9702 Paper 5?
Paper 5 (Planning, Analysis and Evaluation) is a 30-mark written paper consisting of two questions of equal mark value (15 marks each). Question 1 tests experimental planning; Question 2 tests data analysis. Both questions may use physical contexts outside the main syllabus content. Students are assessed exclusively on the quality of their physics reasoning, methodology, and analytical skills — not on recall of the context topic.
Question 1 — Planning an Experiment
Students are given a relationship to investigate and must design a complete experimental method. Mark schemes assess: (1) identification of independent, dependent, and controlled variables; (2) description of a workable experimental method with apparatus; (3) a method for keeping controlled variables constant; (4) safety precautions where relevant; (5) a clear graphical analysis method showing what to plot, what the gradient represents, and how the target quantity would be calculated from the graph.
The most common mark losses in Question 1 are: vague or unworkable methods (‘measure with ruler’ without specifying setup); failure to state how controlled variables are kept constant; omitting a safety consideration when the experiment involves electrical components, heated substances, or stretched materials; and specifying the correct graph axes without explaining what the gradient represents in terms of the sought quantity.
Question 2 — Analysis: Linearising, Graphing, and Uncertainty
Students are given experimental data for a non-linear relationship and must: (1) rearrange the given equation into linear form (y = mx + c); (2) calculate and tabulate processed data values with correct significant figures; (3) plot the linearised graph with labelled axes and error bars; (4) draw a best-fit line and a worst-acceptable line; (5) use the two lines to calculate the gradient, its uncertainty, and the target quantity.
The most consistently penalised errors in Question 2, confirmed by Cambridge Example Candidate Responses, are: giving processed values to more significant figures than the raw data; failing to allow for powers of ten when reading graph gradient (a common 10⁶ error on axes); not indicating the triangles used for gradient calculation; and not drawing or distinguishing the worst-acceptable line from the best-fit line.
How Does a Cambridge 9702 Physics Tutor Help You Score Higher?
Cambridge A Level Physics 9702 online tutoring addresses two distinct types of problems: conceptual gaps in theory topics (oscillations, electric fields, capacitor discharge, nuclear physics) and exam technique gaps in structured papers (Papers 2, 4, and 5). Both types have different root causes and require different tutor interventions. A tutor who conflates the two will address the wrong problem.
- Tutors teach mark-scheme language for structured questions. Cambridge mark schemes for Papers 2 and 4 reward specific phrasing: ‘mention of electrons’, ‘use of correct equation with substitution’, ‘reference to conservation of energy’, ‘answer to correct significant figures with correct unit’. Students who write correct physics in imprecise language lose marks consistently. A tutor who knows Cambridge mark scheme conventions teaches students how to state ideas in creditable form, not just whether the idea is correct.
- Tutors diagnose whether errors are conceptual or procedural. A student who gets wrong answers on D.C. circuit questions may have a conceptual gap (misunderstanding internal resistance) or a procedural gap (applying Kirchhoff’s laws to a loop in the wrong direction). The fix is different in each case. A tutor works through recent past-paper questions, identifies the error type, and targets the specific knowledge or procedure missing.
- Tutors build Paper 5 analysis technique explicitly. The linearisation, graphing, and uncertainty skills in Paper 5 are not covered in depth in most school physics lessons — they are considered practical/lab skills. Students frequently arrive at Paper 5 without having practised transforming a given equation to y = mx + c form, drawing error bars proportionally, or calculating gradient uncertainty from two lines. A tutor who has worked through multiple Paper 5 questions teaches these as a coherent skill set, not as isolated steps. This is a core part of test preparation for 9702.
- Tutors help students interpret and answer ‘explain’ and ‘describe’ questions. Cambridge command words have specific meanings: ‘state’ requires a brief factual answer; ‘explain’ requires a cause-and-effect relationship with physics reasoning; ‘describe’ requires a step-by-step account; ‘define’ requires the exact syllabus definition. Students who answer a ‘describe’ question with an ‘explain’-style response, or vice versa, consistently miss marks. A tutor teaches command-word discipline as a separate exam skill.
- Tutors cover the hardest A2 topics with worked examples. Topics where students consistently struggle — SHM (especially the phase relationship between displacement, velocity, and acceleration), capacitor discharge (understanding the time constant τ = RC and what it means for the decay rate), magnetic induction (Lenz’s law applied to changing flux), and nuclear binding energy per nucleon curves — benefit from a tutor who can build the concept from first principles and then work through past-paper questions in sequence.

Frequently Asked Questions About Cambridge 9702 Physics Help
What is the difference between AS Level and A Level in the 9702 syllabus?
AS Level Physics 9702 covers topics 1–11 and is assessed by Papers 1, 2, and 3. It can be taken as a standalone qualification (giving an AS Level certificate) or as the first year of the full A Level. A Level Physics 9702 requires all 25 topics (11 AS + 14 A2) and is assessed by all five papers. A Level is the full two-year course and carries significantly more weight for university admissions in most countries.
How hard is Cambridge A Level Physics 9702 compared to IB Physics?
Both are rigorous pre-university physics qualifications, but they differ in structure and assessment style. Cambridge 9702 is highly calculation-intensive and assessed through closed-book timed papers with a strong emphasis on precise terminology and mark-scheme language. IB Physics (HL) includes more discussion-style responses and an internal assessment. Students who are strong at structured calculation problems often find 9702 aligns well with their skills; students who prefer more open-ended investigation may find IB more comfortable. Both are well-recognised globally for engineering and science university applications.
Is a formula sheet provided in 9702 Physics exams?
Yes — Cambridge provides a formula sheet with 9702 Physics papers. However, the formula sheet does not include all equations in the syllabus: students must memorise a significant number of equations that are not on the sheet. The syllabus explicitly marks which equations must be recalled and which are given. Knowing which equations to memorise and which will be provided is an important part of exam preparation. The Cambridge Learner Guide for 9702 lists these explicitly.
What are the most commonly dropped marks in Papers 2 and 4?
Cambridge Examiner Reports identify several recurring mark losses: (1) ignoring internal resistance in circuit questions (a common mistake specifically flagged in the Cambridge Learner Guide for 9702); (2) incorrect unit conversion — particularly mm² to m² (a factor of 10⁻⁶, not 10⁻³) and keV to J; (3) giving numerical answers to fewer significant figures than the data warrants; (4) writing physics explanations that are correct but do not use the specific term the mark scheme awards credit for; and (5) losing the second mark in ‘explain’ questions by stating the effect without the cause or mechanism.
Can MEB tutors help with past papers and Paper 5 analysis technique?
Yes. MEB tutors provide homework help and worked solutions to Cambridge 9702 past papers across all five papers, including Paper 5 question-by-question walkthroughs covering linearisation, graphing technique, error bar construction, gradient calculation, and uncertainty determination.
