27 chapter playbooks, one for every chapter still on the paper

The largest chapter on the recent papers. Coulomb's law, field and potential, Gauss's law and capacitors; capacitors alone are a large share, so learn the slab and combination rules cold.

Grown into a cornerstone. Mirrors, refraction, lenses and prisms each come down to one equation used with a fixed sign convention, so the convention is half the chapter.

Dimensions and errors on nearly every paper, and it has grown. Quick questions once the dimensional formulas of the common quantities are known by heart.

Moment of inertia feeds torque, angular momentum and rolling. Many of its questions have numeric answers, so learn the standard results and the two axis theorems exactly.

Still about one question a paper, though smaller than in the early papers. Kirchhoff's laws, bridges, meters and cells; many answers are numbers, so no option will catch a slip.

Young's double slit carries most of it: fringe width, fringe position and intensity. It has grown since the early papers.

The field of a wire, a loop and a solenoid, the force on a moving charge, and the galvanometer conversions. Directions decide many answers.

The first law, the four processes and the heat engine. Read work, heat and internal energy off a P–V graph with the sign convention fixed.

Pressure, Bernoulli, viscosity and surface tension. It has grown since the early papers, and most of its questions are calculations.

Diodes, the Zener regulator and logic gates. Mostly reading a circuit or a truth table; transistors have not been asked in the recent papers.

The photoelectric equation and the de Broglie wavelength. Short questions, few with numeric answers, and the laws are often asked as statements.

The wave equation, energy and intensity, and the order of the spectrum. Mostly recall and one-line calculations.

Projectiles, relative velocity and circular motion. Lighter than in the early papers, but each question is a vector split into two perpendicular parts.

The work-energy theorem, power and collisions. Energy conservation usually beats a force analysis.

Simple harmonic motion, springs and pendulums. Lighter than in the early papers; time-period questions dominate.

Gas laws, molecular speeds and degrees of freedom. Lighter than before; the degrees-of-freedom table answers a large part of it.

Faraday's law, motional emf and inductance. Nearly half its questions have numeric answers.

Field, potential, escape speed and satellites. It has shrunk by almost half since the early papers.

Bohr's model and the hydrogen spectrum: radius, energy and the spectral series. Scaling with Z and n answers most questions.

Young's modulus, stress and strain, and the elastic energy of a stretched wire. Almost every question is a calculation.

Expansion, calorimetry, conduction and cooling. A small chapter of direct calculations.

The equations of motion and graphs of motion. Lighter than in the early papers; read every graph's slope and area.

The wave equation, strings and pipes, beats and the Doppler effect. Half its questions have numeric answers.

Newton's laws, friction and pulleys. Lighter than in the early papers, but its free-body habit runs through all of mechanics.

Mass defect, binding energy and Q-values. Radioactivity has almost stopped appearing, so the binding-energy pages now carry the chapter.

Reactance, impedance, resonance and power in an LCR circuit. It has shrunk by about half since the early papers.

Bar magnets, the earth's field and magnetic materials. A small chapter, mostly recall of the material classes.
