GCE O/L Mathematics study guide
GCE O/L Mathematics · Work through your exam, one topic at a time.
GCE Ordinary Level Mathematics is a school-leaving qualification taken around age 16 in several Commonwealth education systems. It is designed for students who have completed lower-secondary mathematics and need a certification that demonstrates numerical fluency, algebraic manipulation, geometric reasoning and basic statistical literacy. The GCE O/L Mathematics study guide has 7 sections and about 1,895 words.
01Number
The Number domain tests exact arithmetic and numerical reasoning: integers, fractions, decimals, percentages, powers and roots, standard form, rounding and bounds. O Level questions often combine two of these ideas, so keep the order of operations and the unit of the answer in view.
321 words, about 2 min02Algebra
Algebra tests manipulation and solution of equations, formulae, inequalities, sequences and graphs. The exam rewards showing equivalent stages; a correct final answer without a valid intermediate step may still lose method marks in “show that” questions.
250 words, about 1 min03Geometry and Measures
This domain covers angle facts, polygons, circles, mensuration, transformations, similarity and bearings. Questions usually supply a diagram; the marks are for identifying the correct property and applying it with consistent units.
273 words, about 1 min04Statistics
Statistics tests collection, presentation and interpretation of data: averages, frequency tables, cumulative frequency, histograms, scatter graphs and comparing distributions. The exam expects a measure of average and a measure of spread when comparing two data sets.
265 words, about 1 min05Probability
Probability tests the language of chance, sample-space diagrams, tree diagrams and combined events. Probabilities lie from 0 to 1, and the probabilities of all mutually exclusive outcomes sum to 1.
232 words, about 1 min06Ratio, Proportion and Rates of Change
This domain tests comparing quantities multiplicatively and handling compound measures. Expect ratio sharing, direct and inverse proportion, percentages, speed, density, pressure and growth/decay, often in a real-world context.
286 words, about 1 min07Trigonometry
Trigonometry tests right-angled triangle ratios, the sine and cosine rules, areas of triangles, bearings and angles of elevation and depression. Diagrams may be absent, so sketch and label the given information.
