The whole topic on a page or two, for the night before.

A complete 22-page IGCSE guide to percentages. It covers converting between fractions, decimals and percentages, finding a percentage of a quantity, and expressing one quantity as a percentage of another. It then teaches percentage increase and decrease using multipliers, percentage change, and reverse percentages. The final section applies these skills to profit and loss, successive percentage changes, and algebraic “show that” and equation problems. Every method comes with step-by-step worked examples and common mistakes to avoid. It ends with exam tips and a list of common question types.
