Mistake Master
All seven units of the algebra-based AP Physics 2 course framework. They are numbered 9 through 15 here, continuing from AP Physics 1 rather than restarting at 1, because the two courses are one sequence and a unit number should mean one thing across both. The College Board numbers these same seven units 1 through 7 in the Physics 2 CED, so unit 9 here is CED unit 1. Approximate weightings are from the College Board Course and Exam Description; exact weightings vary year to year.

Temperature and pressure as consequences of molecular motion, the ideal gas law and what each variable is allowed to do, thermal equilibrium and the three transfer paths, the first law as energy bookkeeping, specific heat and conductivity, and why entropy sets a direction.
Charge and Coulomb's law as a magnitude plus a direction, charging by friction, contact and induction, electric fields and what field lines do and do not mean, potential energy against potential, and capacitors as geometry.
Current and what actually moves, simple and compound DC circuits, resistance and resistivity, electric power, the loop and junction rules as conservation statements, and the two ends of an RC transient.
Magnetic fields and what they act on, the force on a moving charge and on a current-carrying wire, the field a current produces, and induction: flux, Faraday's law, and the sign Lenz's law fixes.
Reflection and the images plane and curved mirrors form, refraction and total internal reflection, and the ray rules that locate an image in a lens, including when the image is virtual and what that means.
Pulses and periodic waves, what happens at a boundary, polarization, electromagnetic waves, the Doppler effect, interference and standing waves, diffraction, the double slit and gratings, and thin films.
Wave-particle duality, the Bohr model and the spectra it explains, blackbody radiation, the photoelectric effect and what intensity does not change, Compton scattering, and nuclear decay, fission and fusion.
Everything above, mixed together. Open-ended problems with worked solutions, drawn from every unit of the Physics 2 framework, for when you want the question without being told which topic it came from.
All 46 topics ship with a misconception-targeted lesson and a ten-scenario skill check, built on a taxonomy of 168 documented errors. Every unit also has a topic diagnostic, a targeted drill per error and a cumulative exam, drawn from that same taxonomy.
