A Level Physics (9702) combines conceptual understanding with heavy calculation across five papers over AS and A2. Top grades come from fluent formula use, correct units and uncertainty, and strong practical technique.
Physics 9702 has five papers: multiple choice, AS structured, and a practical exam at AS, then A2 structured and a planning and evaluation paper at A2. A formula sheet is provided, but you must apply it correctly with proper units. There is no written alternative to the practical.
This guide covers the five-paper structure, the core topics from mechanics to fields, calculation and uncertainty technique, the practical and planning papers, and how to score top marks.
What Is the A Level Physics 9702 Paper Structure?
The qualification runs across five papers, three at AS and two at A2. Like all Cambridge sciences, it includes dedicated practical assessment.
| Paper | Focus | Format |
|---|---|---|
| Paper 1 | Multiple Choice, 40 questions, AS content | 1h15, 40 marks |
| Paper 2 | AS Structured Questions | 1h15, 60 marks |
| Paper 3 | Advanced Practical Skills, in a lab | 2 hours, 40 marks |
| Paper 4 | A Level Structured Questions | 2 hours, 100 marks |
| Paper 5 | Planning, Analysis and Evaluation | 1h15, 30 marks |
Papers 1, 2, and 3 form the AS qualification. Papers 4 and 5 complete the A Level, with Paper 4 the largest single paper at 100 marks.
A strong AS performance can offset a weaker A2 series, since the full A Level grade combines all papers. A full A Level candidate sits all five, with no option choice or single-paper resits.
What Are the Core Physics Topics?
The syllabus builds from AS foundations to more abstract A2 topics. The AS mechanics and electricity underpin everything that follows.
| Level | Key Topics |
|---|---|
| AS mechanics and matter | Kinematics, forces, momentum, work and energy, deformation of solids |
| AS waves and electricity | Waves, superposition, current, DC circuits |
| A2 fields | Gravitational, electric, and magnetic fields, capacitance |
| A2 modern physics | Quantum physics, nuclear physics, medical physics, astronomy |
Mechanics is the foundation. A weak grasp of forces, motion, and energy makes A2 fields and circular motion much harder, so master the AS core before moving on.
How Do You Master Physics Calculations?
Physics is calculation-heavy, and most marks in the structured papers come from numerical answers. A clear method protects those marks.
- State the formula first, choosing the right one from the provided formula sheet.
- Substitute the values clearly, converting units where needed, such as keV to joules.
- Calculate the answer and write it with the correct unit and sensible significant figures.
- Show every step, since working is credited even if the final answer is wrong.
A formula sheet is provided, but it does not tell you which formula to use or how to convert units. Those decisions are yours, and they are where marks are won or lost.
Uncertainty and significant figures are frequently tested, especially in the practical papers. Learn to calculate absolute and percentage uncertainty, because these are easy marks that many students drop.

Chat on WhatsAppHow Do You Explain Physics in Words?
Not every mark is a calculation. Many questions ask you to explain a phenomenon in terms of physics, and these reward precise reasoning.
Explain in terms of the physics involved, such as forces, energy, or particles, rather than everyday description. Name the principle or law and apply it to the specific situation in the question.
The command word tells you the depth required. State needs a brief fact, explain needs reasoning, and show that needs structured steps leading to a given result. Match your answer to the command word.
Multi-step and synoptic questions combine topics, such as mechanics with energy. Practise linking concepts, since A2 rewards connecting ideas rather than treating each topic in isolation.
How Do the Practical Papers 3 and 5 Work?
Physics assesses practical skills through two separate papers. Knowing the difference shapes how you prepare for each.
Paper 3 is a hands-on practical exam in a laboratory. You set up apparatus, take measurements, record data in tables, plot graphs, and analyse results under timed conditions.
Paper 5 is a written paper testing planning, analysis, and evaluation. You design experiments, identify variables, analyse log graphs and uncertainty, and evaluate methods with specific errors and improvements.
There is no written alternative to the lab-based Paper 3. Private candidates must arrange a centre offering it, as covered in the private candidate A Level guide. Practical methodology is very coachable, so drill it directly.

Chat on WhatsAppFrequently Asked Questions
What Is the Syllabus Code for A Level Physics?
The Cambridge syllabus code for A Level Physics is 9702. It runs across five papers: multiple choice, AS structured, a practical, A2 structured, and a planning and evaluation paper.
How Many Papers Are in A Level Physics 9702?
Five. Papers 1, 2, and 3 at AS, then Papers 4 and 5 at A2. A full A Level candidate sits all five, with no paper option choice.
Is a Formula Sheet Provided in Physics Exams?
Yes. A formula sheet is provided in the exam. However, you must choose the correct formula, convert units, and apply significant figures yourself, which is where marks are decided.
Is There a Practical Exam in A Level Physics?
Yes. Paper 3 is a hands-on laboratory practical. There is no written alternative, so lab work is compulsory. Paper 5 separately tests planning and evaluation in writing.
Why Do I Lose Marks on Calculations?
Usually missing units, wrong significant figures, or unit conversion errors. Always state the formula, show substitution, convert units, and give the answer with its correct unit.
What Is the Difference Between Paper 3 and Paper 5?
Paper 3 is a hands-on lab practical with real apparatus. Paper 5 is a written paper testing planning, analysis, and evaluation, though it still requires real practical experience.
Can Private Candidates Take A Level Physics?
Yes, but they must arrange a centre offering the lab-based Paper 3, since there is no written alternative to the practical. This is the main hurdle for private science candidates.
How Important Is Uncertainty in A Level Physics?
Very. Absolute and percentage uncertainty and significant figures are frequently tested, especially in the practical papers. They are easy marks that many students drop.
Which Paper Carries the Most Marks?
Paper 4, the A Level structured paper, at 100 marks. It covers fields, quantum and nuclear physics, and other A2 topics, and is the largest single paper.
Is A Level Physics Required for Engineering?
Yes. Physics is essential for engineering and is a core pre-engineering subject alongside Mathematics and Chemistry. It is also required for many medical and physical science routes.
Is A Level Physics Hard?
It is demanding because it combines abstract concepts with heavy calculation. Students who build strong mechanics foundations and practise past papers with mark schemes do best.
How Do I Prepare for the Planning Paper?
Do real experiments, then practise past Paper 5 questions. Learn to state variables, write clear methods, analyse log graphs and uncertainty, and give specific errors and improvements.
