About IGCSE and O Level Maths

Cambridge IGCSE Mathematics and Cambridge O Level Mathematics are taken by students aged about 14 to 16 in many countries. IGCSE is offered at Core and Extended level.

Both cover number, algebra and graphs, coordinate geometry, geometry, mensuration, trigonometry, transformations and vectors, probability and statistics. Papers include questions to answer without a calculator as well as with one; check your syllabus for the exact papers.

Exam tips

  • Give answers to the accuracy asked (often 3 significant figures) and keep more figures during working.
  • Learn the formulas that are not given on the paper, such as the quadratic formula and the trigonometric ratios.
  • Practise non-calculator arithmetic with fractions, negatives and surds.
  • Use the mock test below to practise mixed questions, as in the real papers.
