Start with a short set of questions across the topics you have covered. Use the mistakes to choose a focused task, and keep your school syllabus beside you to check coverage.
Topics to check against your syllabus
Use these examples to organise practice alongside your school syllabus. They are not a complete syllabus or a forecast of topic marks. See WAEC Ghana's WASSCE information for official examination guidance.
| Topic area | Examples to practise |
|---|---|
| Algebraic Processes | Simplifying expressions, simultaneous and quadratic equations, factorisation, word problems solved algebraically |
| Geometry & Trigonometry | Angles, bearings, circle theorems, sine/cosine rules, similar triangles |
| Numbers & Numeration | Number bases, indices, standard form, ratios, percentages |
| Statistics & Probability | Mean, median, mode, frequency tables, basic probability |
| Mensuration | Area, perimeter, volume, surface area of common shapes |
| Sets & Logical Reasoning | Venn diagrams, set notation, logical statements |
| Indices, Logarithms & Surds | Laws of indices, simplifying surds, basic logarithm rules |
Practise the links between topics
An algebraic step can appear in a mensuration or statistics problem. Practise recognising the relationship before substituting numbers.
Where students lose marks even when they know the topic
- Sign errors when transposing terms. Moving a term across the equals sign and forgetting to flip its sign is one of the most common ways students lose marks on questions they otherwise understood.
- Order of operations. Applying addition or subtraction before multiplication or division inside an expression, especially under exam pressure when working quickly.
- Area and perimeter mixed up. A surprising number of marks are lost not because students can't calculate area or perimeter, but because they calculate the wrong one for the question asked.
- Treating probability as if it can exceed 1. A probability answer greater than one or less than zero should be an immediate signal that a step earlier in the working went wrong.
- Rushing word problems into equations. Setting up the wrong equation from a word problem, usually by misreading what the unknown actually represents, before any of the algebra even starts.
How WAEC actually asks questions in this subject
Core Mathematics questions tend to follow a small number of recognisable shapes: direct computation, solving for an unknown, word problems that need to be translated into an equation first, reading values off a chart or diagram, and multi-step questions that chain two or three of the above together. Once you can recognise which shape a question is, you know roughly which method to reach for before you've even finished reading it.

How to prioritise your revision from here
Practise algebra, geometry and number work alongside the remaining topics in your syllabus. Give extra time to the steps you cannot explain, then revisit them after a gap.

Is Core Mathematics compulsory for WASSCE?
Yes. Core Mathematics is one of the core/compulsory subjects for all SHS candidates in Ghana, regardless of programme, alongside English Language and Integrated Science.
How should I choose a Core Mathematics topic to revise?
