How to Revise iGCSE Physics

Revising Physics requires a blend of memorisation and understanding. You need to recall key facts, definitions, and processes, but you also need to understand the underlying principles well enough to apply them to unfamiliar scenarios. Start each topic by learning the core concepts, then test yourself with application questions that require you to use your knowledge in new contexts.

Diagrams are one of the most powerful revision tools for Physics. Whether it is the structure of a cell, an energy level diagram, or a circuit, being able to draw and label diagrams from memory cements your understanding far more effectively than re-reading text. Practise reproducing key diagrams until you can do so accurately without any reference material.

Do not neglect the practical and mathematical elements. Physics exams include questions on required practicals and expect you to perform calculations confidently. Practise interpreting data tables, plotting graphs, calculating rates and percentages, and evaluating experimental methods. These skills are tested every year and are straightforward marks if you have prepared.
