What the exam asks of you
OCR A-Level Physics B, Advancing Physics, teaches physics through the contexts it is used in: imaging and signalling, sensing circuits, the mechanical properties of materials. It treats quantum behaviour with phasors rather than as a wave against particle argument.
It is three written papers plus a separately reported practical endorsement. Fundamentals of Physics carries 41 per cent, Scientific Literacy in Physics 37 per cent and Practical Skills in Physics 22 per cent, and all three can draw on any of the six teaching modules.

What is in the guide
All 21 topics
Every topic has its own page with its subtopics, what it covers and sample questions.
Sample questions
Taken from the guide. Answer each one closed book first, then open the answer.
-
Choosing apparatus and techniques
What can a preliminary trial tell a planner?
Show the answer
It shows whether the dependent variable changes measurably over the chosen range, and whether the apparatus, timings and resolution are adequate before time is spent on a full set of readings. -
Using apparatus and techniques correctly
What must be done before a thermometer reading is taken?
Show the answer
The bulb must be fully immersed in the substance and left long enough for the thermometer to reach the same temperature as it. -
Processing results and reaching conclusions
Why is extrapolating a long way beyond the measured range unsafe?
Show the answer
There is no evidence that the relationship continues to hold outside the range tested, and a different physical behaviour may take over. -
Drawing conclusions and identifying anomalies
What can cause a single anomalous reading?
Show the answer
A misread or mistyped value, and a momentary change in conditions such as a loose contact, a draught or the apparatus being disturbed. -
Investigative approaches and solving practical problems
A quantity cannot be measured directly. Describe the general strategy for obtaining it.
Show the answer
Measure quantities that can be read directly and are linked to it by a known equation, then combine them, preferably from the gradient of a graph rather than a single set of values. -
Analogue apparatus and interpolation
Why should a spring newtonmeter be zeroed while held in the direction in which it will be used?
Show the answer
The weight of its own moving parts acts along that direction, so the zero shifts if the instrument is checked horizontally and then used vertically. -
Factors affecting accuracy and uncertainty
Distinguish the two kinds of contribution to the difference between a measurement and the true value.
Show the answer
Random contributions scatter readings either side of the true value and are reduced by averaging repeats, while systematic contributions shift every reading the same way and are not. -
Real images and the curvature of wave-fronts
Explain why the curvature added by a given thin lens is the same wherever the object is placed.
Show the answer
The curvature added depends only on the shape of the lens surfaces and its refractive index, neither of which changes when the object moves.
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.

- What is parallax error and how is it avoided when reading a scale?
- Where in a circuit is an ammeter connected, and where is a voltmeter?
- Why should a voltmeter have a very high resistance?
- Why should an ammeter have a very low resistance?
- Why is apparatus clamped to a stand rather than held by hand while readings are taken?
- What must be done before a thermometer reading is taken?
- How should the volume of water in a measuring cylinder be read?
- How is a set square used when apparatus must be vertical or horizontal?
- What does a plumb line establish, and how?
- It is the error caused by viewing a scale from an angle, and it is avoided by placing the eye directly in line with the mark being read, using a mirror scale or a set square where one is available.
- The ammeter is connected in series with the component so the same current passes through it, and the voltmeter is connected in parallel across the component.
- So that it draws almost no current from the circuit and therefore does not change the potential difference it is measuring.
- So that it adds almost no resistance to the circuit and therefore does not reduce the current it is measuring.
- A hand cannot hold a position steady, so the quantity being measured drifts while the reading is taken and the arrangement cannot be reproduced for the next reading.
- The bulb must be fully immersed in the substance and left long enough for the thermometer to reach the same temperature as it.
- The cylinder is placed on a level surface and the bottom of the meniscus is read with the eye at the same height as the liquid surface.
- One edge is placed along the bench or a rule and the other against the apparatus, so that the right angle shows whether the apparatus is truly perpendicular to it.
- It establishes the true vertical, because a mass hanging freely on a thread settles along the direction of the gravitational force.

Questions students ask first
Is this the right specification? I have seen H556 mentioned.
This guide is Physics B, Advancing Physics, H557. The other OCR specification is Physics A, H556, which is organised by topic in six modules.
They are different courses and the guides are not interchangeable. If your code is H556 you need the Physics A guide.
I have heard H557 is being withdrawn. Does that affect me?
It does not affect the exam you sit. OCR is withdrawing H557: the last first teaching was September 2026 and the final assessment is summer 2028, with no resit opportunity after that.
If you are sitting your A-Level in 2027 or 2028 you are on H557 and this is your guide.
Which topics are on which paper?
All of them, on all three. Each component can draw on any of the six teaching modules. The papers differ in style: Component 01 is fundamentals, Component 02 is scientific literacy and Component 03 is practical skills.
Are phasors covered?
Yes. Waves and Quantum Behaviour is 179 questions and treats quantum behaviour with phasors as the specification does, rather than as the wave against particle account used on other specifications.
