A-Level Physics · Learn
40 lessons in 11 units, about 64 h 30 min of reading and core practice. Each lesson ends with a quick check.
Specification
Unit 1
The skills every board examines everywhere: SI units and estimation, the maths toolkit (at least 40% of marks), uncertainties, graphical analysis, the required/core practicals and experimental design (at least 15% of marks).
5 lessons · 8 h 25 min of study · ≈14% of the test
Unit 2
Forces, motion, momentum, energy and the properties of materials and fluids — the foundation that every later topic (fields, oscillations, thermal physics) reuses.
7 lessons · 11 h 20 min of study · ≈18% of the test
Unit 3
Charge, current, potential difference, resistance and d.c. circuits, from microscopic drift velocity to potential dividers and internal resistance.
3 lessons · 5 h 10 min of study · ≈9% of the test
Unit 4
Progressive and stationary waves, superposition, interference, diffraction, polarisation and refraction — heavily examined in MCQs and practical contexts.
4 lessons · 6 h 20 min of study · ≈10% of the test
Unit 5
Photons, the photoelectric effect, energy levels, wave–particle duality, the particle zoo and the conservation laws that govern interactions.
3 lessons · 5 h of study · ≈8% of the test
Unit 6
Periodic motion: angular speed and centripetal force, simple harmonic motion and its energy, damping, forced oscillations and resonance.
3 lessons · 4 h 30 min of study · ≈7% of the test
Unit 7
Internal energy, heating and phase change, the ideal-gas laws, kinetic theory and (for some boards) the first law of thermodynamics and heat engines.
3 lessons · 4 h 25 min of study · ≈6% of the test
Unit 8
Gravitational, electric and magnetic fields, capacitors and electromagnetic induction — the highest-mark A2 content on every board.
6 lessons · 10 h 25 min of study · ≈17% of the test
Unit 9
Nuclear structure, radioactive decay and its exponential mathematics, radiation dose and safety, and energy from binding energy via fission and fusion.
3 lessons · 4 h 50 min of study · ≈7% of the test
Unit 10
Compulsory for OCR A, Edexcel, Eduqas/WJEC, CCEA, Cambridge and IAL; the most popular AQA Paper 3 option (with telescopes as AQA-only content).
2 lessons · 2 h 45 min of study · ≈4% of the test
Unit 11
Compulsory medical imaging for OCR A and Cambridge; an option for AQA and Eduqas/WJEC.

Measurement, maths and practical skills · Lesson 1 of 5
SI base and derived units, prefixes, homogeneity of equations, orders of magnitude, and the algebra, trigonometry, logarithm and rate-of-change skills that underpin every calculation.
