The book above contains practical applications of the NEC such as Ohm‘s Law, series/parallel circuits, voltage drop, load calculations, motor phases, impediance, inductance and math formulas you are expected to know.  The basic knowledge covered in the exam is assumed and not usually listed as subjects covered.
