Integrated Board-specific and Optional Extensions
Orienting study across space and cosmology, medical imaging, engineering and rotating systems, electronics and signals, sports, energy and historical-development contexts without treating them as separate universal modules.
How to study A-level Physics
Define the system, represent the physics, select a justified model, calculate transparently, then test the result against units, limits and evidence.
Core concepts
Concept 1
Extension status varies: some ideas are compulsory on one route, optional on another and absent from a third.
Exam cue: Confirm the exact specification code and school-selected option before studying detail.
Concept 2
AQA selects one of five Paper 3 options, Eduqas selects one of four Component 3 options, while Pearson and OCR routes embed their own compulsory extensions.
Exam cue: Map each extension back to the common physical principles and mathematical models it uses.
Concept 3
The transferable method is to apply shared mechanics, fields, waves, thermal, quantum, nuclear and data principles to the board-specified context.
Exam cue: Use the board's current data or formula booklet, practical guidance and assessment materials for depth and notation.
Risk pitfalls and guardrails
Studying every board's option as though all were examinable for one entry.
Guardrail: Do not substitute a memorised formula until you have identified the system, variables, direction, assumptions and valid range of the model.
Assuming astrophysics or medical physics has the same compulsory status on every route.
Guardrail: Do not substitute a memorised formula until you have identified the system, variables, direction, assumptions and valid range of the model.
Using this integrated orientation topic instead of the current specification for an exact option boundary.
Guardrail: Do not substitute a memorised formula until you have identified the system, variables, direction, assumptions and valid range of the model.
Memory anchors
AQA Option Rule
AQA 7408 Paper 3 Section B assesses one selected option, not all five.
Eduqas Option Rule
Eduqas A420QS Component 3 Section B assesses one selected option from four.
Embedded Extension
Pearson and OCR routes place specification-specific applications within compulsory content rather than a shared option menu.
Common-core Anchor
Start from the shared principle, then learn the depth and context required by the entered specification.
Verify the Code
Specification code, cohort updates and centre choice determine the examinable extension.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A learner's selected route includes astrophysics. Why can stellar spectra reveal atmospheric composition?
In an astrophysics extension, a star has luminosity 3.8 × 10²⁶ W. What flux reaches a planet 1.5 × 10¹¹ m away, using F = L/(4πr²)?
