A Level Physics Topic Order for 2026: What to Study First for Smarter Revision
A Level Physics topic order works best when you learn in a dependency-based sequence: Start with Measurements/uncertainties, then Mechanics and Materials, before moving into Electricity and Waves.
After that, progress to Particle Physics, Further Mechanics (including SHM), and then Fields (Gravitational, Electric, Magnetic), followed by Capacitance and Thermal Physics, finishing with deeper Quantum Physics and an optional module like Astrophysics/Medical/Engineering Physics.
This order builds synoptic links early and reduces common misconceptions that cost marks in Year 13 exam questions.
Optimizing Your A Level Physics Topic Order
Based on our years of practical tutoring at Times Edu, the fastest progress in A Level Physics comes from learning topics in a dependency-driven sequence, not the order you happen to meet them in class.
Your goal is to build a “concept stack” where every new chapter reuses earlier tools (vectors, conservation laws, fields, calculus-style gradients, uncertainty). That is what turns revision into retrieval practice rather than relearning.
A critical detail most students overlook in the 2026 exam cycle is that examiners reward linked reasoning more than “chapter recall.” They want you to treat Mechanics, Electricity, Waves, Fields, and Particle Physics as one connected model of nature, then show those synoptic links under time pressure.
A dependency-first Scheme of work (why “topic order” matters)
A strong Scheme of work does three things at once: It respects prerequisites, it aligns with exam weighting patterns, and it schedules practical skills early so uncertainty and data handling become automatic. For AQA [1], assessments are taken at the end of the two-year course, so your sequencing must support long-horizon retention.
If you learn in a poor order, you get predictable failure modes. Students “know” a definition, then lose marks because they cannot convert it into a model, a diagram, or a justified assumption.
Common misconception pattern we see every year
- Treating formulae as the content, rather than the summary of a model.
- Ignoring units and proportional reasoning until revision, then bleeding marks on “easy” questions.
- Delaying uncertainties and practical write-ups, then panicking on analysis questions and required practical-style items.

Starting with Foundational Mechanics and Materials
From our direct experience with international school curricula, the highest ROI starting block is Measurements + Mechanics + Materials. This is where you build the language of modelling: Free-body diagrams, component resolution, conservation, linearisation, and uncertainty.
Recommended starting order (first 6–10 weeks)
Measurements and Units
- SI base units, derived units, prefixes, dimensional analysis.
- Uncertainties, significant figures, gradients, intercepts, error bars.
- Data handling routines you will reuse in every topic (including Particle Physics experiments).
Mechanics (core)
- Kinematics: Graphs, SUVAT logic (not memorization).
- Forces and Newton’s laws: Modeling assumptions, terminal velocity thinking.
- Work, energy, power: Transfers and efficiencies.
- Momentum and impulse: Collision modeling, graphs, area-under-curve reasoning.
Materials
- Hooke’s law [2], elastic vs plastic, stress–strain, Young modulus.
- Energy stored in springs: A key synoptic bridge to SHM later.
Why this is the best foundation
Mechanics is the “grammar” of A Level Physics. It also trains you in modelling judgement, which is where top grades are earned.
Examiner logic to internalize
- You get marks for a correct diagram, a justified model, and a coherent chain of reasoning.
- You lose marks when you skip assumptions (“smooth”, “uniform”, “negligible”) or when you write equations with no defined variables.
Mini-table: Core prerequisites you must lock in early
| Later topic | What you must already be fluent with | Why it matters in mark schemes |
|---|---|---|
| Electricity (circuits) | proportional reasoning, gradients, units | V–I graphs, resistivity, interpretation |
| Waves | graph reading, trig, energy language | phase, intensity, superposition |
| Fields | vectors, inverse-square, energy-work | deriving/using field strength & potential |
| Particle Physics | exponentials, uncertainty, units | decay graphs, log plots, data analysis |

Introducing Waves and Electricity Concepts
Based on our years of practical tutoring at Times Edu, the pedagogical approach we recommend for high-achievers is to run Electricity and Waves in parallel, after Mechanics is stable. That pairing builds mathematical maturity without overwhelming working memory.
Electricity (start with charge flow, then circuits)
Sequence
- Charge, current, potential difference, resistance.
- I–V characteristics and resistivity (link to Materials thinking).
- Circuit rules (Kirchhoff style reasoning).
- Power in circuits and efficiency.
Misconceptions that cost a lot of marks
- “Current gets used up.” It does not; energy is transferred, charge flow is conserved.
- Confusing potential difference with potential energy; V is energy per unit charge, not “energy.”
- Treating circuit equations as algebra-only, without a clear diagram and direction conventions.
Waves (build concept → representation → applications)
Sequence
- Wave basics: Displacement, phase, wavelength, frequency, speed.
- Superposition and interference (with careful sign and path difference work).
- Stationary waves (strings, air columns).
- Refraction and diffraction as modelling outcomes, not “facts.”
Synoptic links you should make on purpose
- Energy transfer: Compare wave intensity with power in circuits.
- Graph skills: Phase difference and kinematics graph literacy are cousins.
Table: Parallel track plan (8-week example Scheme of work)
| Week | Electricity focus | Waves focus | Practical / skill outcome |
|---|---|---|---|
| 1–2 | definitions, units, I–V | wave parameters, graphs | uncertainty + graph gradients |
| 3–4 | resistivity, power | superposition, interference | linearisation practice |
| 5–6 | circuit modelling | stationary waves | structured explanations |
| 7–8 | exam-style mixed problems | refraction/diffraction | timed questions + method marks |

Progressing to Fields and Nuclear Physics
Once Mechanics, Electricity, and Waves are “working tools,” you can move into the more abstract but high-yield core: Fields, Capacitance, and Particle/Nuclear Physics.
Fields (Gravitational Fields, Electric Fields, Magnetic Fields)
Fields are where many students plateau because they try to memorise definitions instead of mapping relationships.
Recommended order
Gravitational Fields
- Inverse-square thinking and field strength.
- Potential and potential energy.
- Orbital motion links to circular dynamics (from Mechanics).
Electric Fields
- Force on charges, field strength, potential.
- Parallels to gravitational language (same maths, different constants).
Magnetic Fields
- Force on moving charges and currents.
- Flux and induction thinking if your board includes it.
This order is efficient because Gravitational Fields feel physically intuitive, then you reuse the same model structure in Electric Fields, then move into Magnetic Fields where vector directions and right-hand rules demand confidence.
Capacitance (often the “hidden grade booster”)
Capacitance rewards students who can handle:
- Exponential behaviour and time constants,
- Energy stored and energy transfer,
- Data interpretation from charging/discharging graphs.
AQA explicitly separates written exam grades from the separate practical endorsement, so your written modelling must be sharp even if your hands-on skills are strong.
Particle Physics and Nuclear Physics
Order
- Particles, antiparticles, conservation rules.
- Radiation, interactions, detectors (link to uncertainties and data).
- Nuclear decay, half-life, exponentials, activity.
- Binding energy, fission/fusion, energy per nucleon graphs.
Common misconceptions
- Half-life is not “time to decay completely.”
- Activity is not “how dangerous”; it is decay rate.
- Conserved quantities are not optional; if your conservation statement is wrong, the explanation collapses.

Linking Synoptic Topics for Year 13 Revision
Year 13 (A2) is where students either become exam-robust or become overwhelmed by content density.
From our direct experience with international school curricula, you should treat Year 13 as a synoptic construction project where each new unit explicitly connects backward.
Typical Year 13 topic set (varies by board)
Most specifications include:
- Further Mechanics (circular motion, Simple Harmonic Motion, oscillations).
- Fields (Gravitational, Electric, Magnetic Fields).
- Capacitance.
- Thermal Physics (ideal gases, first law ideas, specific heat concepts).
- Quantum Physics / Particle Physics at a deeper level.
- An applied option such as Astrophysics, Medical Physics, or Engineering Physics depending on the board.
OCR [3] notes that specification updates can occur without changing the assessment requirements, so you should still track versioning but focus on outcomes and skills.
Synoptic links you should drill (this is where A/A* live)
| Anchor idea | Appears in | How it shows up in exams |
|---|---|---|
| Energy conservation | Mechanics, Electricity, SHM, Nuclear | multi-step calculations + explanations |
| Fields and potentials | Gravitational/Electric | compare models, derive relationships |
| Exponentials | Capacitance, Radioactive decay | graph interpretation, logs, time constants |
| Uncertainty | Practicals across the spec | gradients, % uncertainty, evaluation |
A revision structure that actually works (12-week model)
- Weeks 1–4: Rebuild fundamentals with mixed-topic sets (Mechanics + Electricity + Waves).
- Weeks 5–8: Fields + Capacitance + Particle Physics problem blocks.
- Weeks 9–12: Full-paper practice with a targeted error log.
Your error log should not say “revise waves.” It should say “lost method marks because I didn’t define phase difference and sign convention.”
Grade boundaries: How to use them without being misled
Grade boundaries shift by year and by board, so you cannot chase a fixed “A is 70%” myth. Use boundaries to calibrate how many marks you can drop and still hit your target, then build a buffer.
Authoritative boundary documents exist by board (AQA archive, OCR June 2025 boundary tables, Pearson June 2025 boundary document).
Practical use
- Aim for “target grade + 10–15 raw marks” in timed papers to offset bad-day variance.
- Identify which question types are consistently expensive for you (explanations, graphs, multiple-step derivations).
Subject choice for study abroad: Strategic guidance (Times Edu lens)
Parents often ask whether Physics is “worth it” if a student is not applying for Engineering. Based on our years of practical tutoring at Times Edu, Physics is a high-signal subject for competitive STEM admissions, and it also complements Economics/Math pathways when paired well.
It is strongest when combined with Mathematics, and it becomes even more persuasive if you can explain applied interests like Medical Physics or Engineering Physics through projects, Olympiad-style problem solving, or research-style writing.
Fast decision rules
- Engineering/Physics majors: Physics + Math is close to non-negotiable.
- Medicine/Biomed: Physics helps, but only if it does not drag down grades; Biology/Chemistry priorities often dominate.
- Architecture/Design: Physics can help for problem-solving credibility, but portfolio and Maths may matter more.

Frequently Asked Questions
What order should I learn A Level Physics topics?
A high-performing order is: Measurements and Units → Mechanics → Materials → Electricity → Waves → Particle Physics → Further Mechanics (including Simple Harmonic Motion) → Fields (Gravitational Fields, Electric Fields, Magnetic Fields) → Capacitance → Thermal Physics → deeper Quantum Physics → optional Astrophysics / Medical Physics / Engineering Physics.This order respects prerequisites and keeps synoptic links active from the start. If your school teaches a different order, you can still self-study in this sequence while matching homework deadlines.
Is it better to teach Mechanics or Electricity first?
Mechanics first is usually the smarter choice for most students, because it builds modelling discipline (diagrams, vectors, conservation) that later makes Electricity far easier. Electricity first can work for a minority profile: Students with very strong Maths fluency and prior circuit exposure, who will not confuse current, potential difference, and resistance.If you want the safest route to A/A*, start with Mechanics, then introduce Electricity once students can translate a word problem into a diagram and a justified set of equations.
What are the Year 13 Physics topics?
Year 13 typically includes Further Mechanics (circular motion and Simple Harmonic Motion), Fields (Gravitational, Electric, Magnetic), Capacitance, Thermal Physics, and deeper Particle Physics / Quantum Physics, plus an applied module such as Astrophysics, Medical Physics, or Engineering Physics depending on the exam board.The exact packaging differs, but these ideas are the common backbone across major boards. Treat Year 13 as synoptic training, not “new chapters only.”
Can you learn Fields without knowing Mechanics?
Which is the hardest topic in A Level Physics?
For many international students, Magnetic Fields and Capacitance are the biggest mark-loss zones because they combine abstract models with direction conventions and multi-step reasoning.Particle Physics can also feel hard, but it becomes manageable when you treat it as conservation-law logic plus careful definitions. The hardest topic is usually the one you learned without strong prerequisites, not the one that is inherently most complex.
How do topics overlap in A Level Physics?
Does the order of practicals matter?
Yes, because practical skills are cumulative: Uncertainty handling, calibration, linearisation, and evaluation should be trained early and reused often. If you delay practical-style thinking, you lose easy marks on data questions and written “required practical” style prompts.Also note that practical endorsement is reported separately from written exam grades in some systems, so you still need written-model strength even with good lab performance.
Conclusion
Based on our years of practical tutoring at Times Edu, the fastest improvement happens when we match your topic order to three inputs: Your current gaps, your exam board (AQA/OCR/Edexcel or International variants), and your university timeline.
If you share your exam board and target grade, Times Edu can build a tailored Scheme of work with:
- A topic-by-topic order aligned to prerequisites,
- A weekly problem-set plan (including synoptic links),
- Practical skills checkpoints,
- And exam-technique drills calibrated to real grade boundary behaviour across recent series.
