Most of the marks lost in physics are lost in the algebra, not the physics. Rearranging, powers of ten, units, significant figures, graphs and vectors — the ten skills every formula needs, drawn.

Understanding a chapter and starting a problem are two different skills. 50 problems worked line by line, with what you know, what you want, and the working in between — plus room to try it yourself first.

Fields, induction, nuclear, thermodynamics and simple harmonic motion: the five that separate a good grade from a top one, each drawn the same way as the main book.
