WASSCE Core Mathematics: Every Topic, and How Much of the Exam Each One Is Worth
Core Mathematics doesn't test every topic equally. Knowing which ones carry the most weight changes how you should be spending your revision time.
On this page
Ask most SHS students what Core Mathematics covers and you'll get a shrug or a list that starts with whatever they learned most recently. That's a problem, because the syllabus isn't flat. Some topics show up in nearly every paper WAEC sets, and some show up rarely. If your revision time is limited, and it always is, the order you tackle topics in matters as much as how well you learn each one.
The main topic areas and roughly how much they're worth
The figures below are approximate weightings based on the general shape of the syllabus and how WAEC has historically distributed questions across topics. Treat them as a guide for where to put your effort, not a guarantee of exactly how any single year's paper will be split.
| Topic area | Roughly how much of the paper | What it includes |
|---|---|---|
| Algebraic Processes | About a fifth of the paper | Simplifying expressions, simultaneous and quadratic equations, factorisation, word problems solved algebraically |
| Geometry & Trigonometry | About a fifth of the paper | Angles, bearings, circle theorems, sine/cosine rules, similar triangles |
| Numbers & Numeration | Just under a fifth | Number bases, indices, standard form, ratios, percentages |
| Statistics & Probability | Around an eighth | Mean, median, mode, frequency tables, basic probability |
| Mensuration | Around an eighth | Area, perimeter, volume, surface area of common shapes |
| Sets & Logical Reasoning | Smaller share | Venn diagrams, set notation, logical statements |
| Indices, Logarithms & Surds | Smaller share | Laws of indices, simplifying surds, basic logarithm rules |
Why these two matter more than the rest
Algebraic Processes and Geometry & Trigonometry aren't just the biggest topics on their own. Questions in Mensuration and Statistics often require an algebraic step to actually solve, so weakness in algebra quietly costs you marks in topics you thought you'd already covered.
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
Start with Algebraic Processes and Geometry & Trigonometry, since they carry the most weight and underpin several other topics. Then work through Numbers & Numeration, since indices and standard form questions are quick to master and rarely skipped by WAEC. Leave Sets and the smaller topics for later, not because they don't matter, but because they take less time to bring up to standard once the bigger topics are solid.
