Why Physics 9702 Paper 2 Is More Than Just Calculations
Cambridge’s Physics 9702 Paper 2 is a 1-hour-15-minute structured question exam worth 60 marks. Unlike Paper 1, this exam does not simply test whether you know the answer. It tests whether you can communicate Physics clearly, logically, and in the exact way Cambridge examiners expect.
Many students lose marks even when they understand the topic because they:
skip steps in calculations
round too early
fail to explain physical principles
forget units
write vague explanations
hide working in their calculator
Paper 2 rewards method and reasoning just as much as final answers.
That is why students who “know the content” still sometimes struggle to achieve top grades.
The Biggest Mistake Students Make in Structured Questions
One of the most common examiner comments every year is that students fail to explain their reasoning properly in “state and explain” questions.
Cambridge does not reward vague scientific language. Explanations must directly connect to Physics principles.
For example, simply writing: “The object slows down because of resistance”
is often too weak on its own.
Students must explain:
which force is acting
how it affects acceleration
what happens to energy or momentum
why the change occurs physically
The explanation is often where the marks actually are.
Many candidates incorrectly assume that stating the answer is enough. In reality, poorly explained answers frequently lose the mark entirely.
Significant Figures Can Quietly Cost Marks
One of the easiest ways to lose marks in 9702 Paper 2 is through incorrect rounding.
Examiner reports repeatedly remind students that final answers should normally be given to three significant figures unless the question states otherwise.
Students often:
round too early during calculations
mix decimal places with significant figures
copy calculator values incorrectly
lose accuracy through repeated rounding
The safest approach is:
Keep extra digits throughout your calculations
Round only at the final answer
Always include units
This small habit can prevent unnecessary mark loss across the entire paper.
Why Showing Full Working Matters
Many students try to save time by skipping steps in calculations.
This is extremely risky in Paper 2 because Cambridge uses Error-Carried-Forward (ECF) marking.
If your early answer is incorrect but your method afterwards is physically correct, examiners can still award follow-through marks.
However, ECF only works if your working is visible.
Strong candidates always:
write the formula first
substitute values clearly
show rearrangement steps
include units consistently
make assumptions obvious
This creates multiple opportunities for method marks even if the final answer is wrong.
For example, students often begin calculations with equations like:
F=maF = maF=ma
or
V=IRV = IRV=IR
VsV_sVs
V
RRR
Ω\OmegaΩ
I=VsR=12.0 V6.0 Ω=2.00 AI = \frac{V_s}{R} = \frac{12.0\,\mathrm{V}}{6.0\,\Omega} = 2.00\,\mathrm{A}I=RVs=6.0Ω12.0V=2.00A
Vs = 12.0 V+-R = 6.0 ΩI = 2.00 A
The formula itself may only be worth one mark, but showing correct structure allows examiners to award ECF marks later in the calculation chain.
What Makes Hill Education Different?
At Hill Education, we teach students far more than Physics theory. We teach students how Cambridge awards marks.
Most revision resources focus only on solving questions. Our system focuses on:
examiner logic
structured-answer technique
method mark optimisation
explanation quality
significant figure accuracy
ECF strategy
command word interpretation
common Paper 2 mistakes
Students often discover that their biggest weakness is not Physics knowledge itself, but understanding how to present answers in a Cambridge-friendly way.
That is why our lessons combine:
structured revision PDFs
examiner-focused walkthroughs
worked solutions
video explanations
paper-specific strategy training
guided self-marking systems
Everything is designed around helping students think like examiners, not just memorise formulas.
Final Advice for May/June 2026 Physics 9702 Candidates
As May/June 2026 approaches, students should spend less time passively reading notes and more time actively writing full structured answers under timed conditions.
After every question, ask yourself:
Did I explain the Physics clearly?
Did I show every important step?
Did I round correctly?
Did I include units?
Would an examiner follow my logic easily?
The students who score highest in Paper 2 are usually not the fastest students. They are the clearest thinkers.
If you are revising for Physics Paper 2, our Significant Figures and ECF Strategy Guide was specifically designed to help students maximise method marks, improve structured answers, and avoid the most common examiner-reported mistakes before the May/June 2026 exams.
