Prep tip

Section A is 28 objective questions worth 40 marks, so learn the definitions, units and formulas of every lesson. In Section B, show the formula, the substitution with units and the answer for every numerical, and draw labelled diagrams for ray optics, circuits and devices.

Suggested order: Unit I, then II, then III, then IV, then V, then VI, then VII, then VIII, then IX, then X, then XI, then XII, then XIII, then XIV, then XV, then XVI, then XVII, and XVIII last.
