A-Level Physics Past Papers & Drilling (Paper 5): Planning, Uncertainty, Evaluation
TUTORZONE ORIGINAL DRILLING MOCK · CAMBRIDGE A-LEVEL PHYSICS (9702) PAPER 5
Written to the Cambridge 9702 syllabus (2025-2027): Paper 5 Planning, Analysis and Evaluation, 30 marks, 1 h 15 min (2 questions, AO3, A Level practical skills). Also Paper 1 MCQ (40), Paper 2 AS structured (60), Paper 3 practical (40) and Paper 4 A Level structured (100). This is a Paper 5 drilling mock: 3 questions for 45 marks of practice, with answers and techniques.

Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Paper 5 (Planning, Analysis and Evaluation) | 2 questions, 30 marks | A Level 12% | 1 h 15 min |

A-Level Physics Paper 5 drilling technique: the plan needs instruments, range, precision, method, controls and the graph relationship; evaluation uses percentage uncertainty = error / reading x 100%; reduce error by repeating, using larger readings and avoiding zero error.
How this paper was built
This is a TutorZone original drilling mock: the questions follow the Cambridge 9702 structure (Paper 5, 30 marks) and the answers are our own, not Cambridge past papers or marking references.
Every numeric answer was recomputed programmatically.
Pacing
| Section | Marks | Suggested time | What to do first |
|---|---|---|---|
| Paper 5 (Planning, Analysis and Evaluation) | A Level 12% | about 37 min per question | plan + graph + error evaluation |
| Paper 3 (Advanced Practical Skills) | AS Level 23% | about 60 min per question | hands-on + record + analyse |
How is percentage uncertainty found?
Direct answer: error / reading x 100%; 10.0 cm ± 0.5 cm gives 5%.
Paper 5: planning and evaluation drilling (3 demonstrated)
Plans need instruments, range, precision and controls; evaluations use percentage uncertainty.
Question 1 (15 marks)
Plan an experiment to determine a spring’s force constant k and explain how to reduce uncertainty.
Question 2 (15 marks)
A reading is 10.0 cm with an instrument precision of ±0.5 cm. Find the percentage uncertainty and evaluate the data’s reliability.
Question 3 (15 marks)
Explain why timing many oscillations (e.g. 20) is more accurate than timing one.
What should an experiment plan include?
Direct answer: instruments (range and precision), controlled variables, measurement steps, repeats, and the graph and gradient relationship.
Paper 5 answers
Question 1
(1) Measure each mass and the extension (instrument, range, precision) (5). (2) Plot F against x; the gradient is k (5). (3) Repeat readings, average, and use larger extensions to cut percentage uncertainty (5).
Question 2
Percentage uncertainty = 0.5 / 10.0 x 100% = 5% (7). 5% is acceptable, but check systematic error (zero error) and random error (repeats) (8).
Question 3
The human reaction-time error is fixed (7), so dividing by the number of oscillations reduces the percentage error (8).
Which topics does this paper drill?
Direct answer: experiment planning, spring constant, percentage uncertainty, systematic and random error, timing oscillations.
Where these marks are usually lost
| Mistake | What it looks like | What it costs | Instead |
|---|---|---|---|
| Plan missing precision | ‘Use a ruler’ | State range and precision | range + precision |
| Uncertainty denominator | Divide by the error | Divide by the reading | 5% |
| Single reading | Measure once | Repeat and average | repeat |
How to use this paper
First drill: the full 1 h 15 min on 2 questions with no references.
Mark it: check the instrument specifications and uncertainty calculations.
Second drill: redo three to seven days later, aiming to finish inside 1 hour.
What should I do after drilling this paper?
Direct answer: log plans missing precision or repeats; redo in three to seven days; and drill Paper 3 practical skills.

Next step: find a tutor / register as a tutor
After drilling, the hard part is telling a conceptual error from a writing error. Tell us the year group, the school and your available times, and TutorZone will match you with a tutor who knows the HKEAA assessment requirements.
Demand for tutors in this subject is steady, and those who can explain the marking scheme and where marks are won are especially sought after. Register free; you pay only when a match succeeds.
