WASSCE Core Mathematics Tips (Ghana): Score Higher in 2027

Core Mathematics is the subject that decides more university applications than any other. Every WASSCE school candidate in Ghana takes it, and universities look for a credit (A1 to C6) in it. If you can raise your Mathematics, you raise your options.

This guide is about method. We have not seen a public WAEC Ghana syllabus document to quote line by line, so we will not claim to know the exact paper layout. Ask your teacher for the current WAEC Core Mathematics syllabus and use this guide to turn it into a plan.

Why Core Mathematics matters

WAEC Ghana lists Mathematics (Core) as one of four core subjects for school candidates, with English Language, Integrated Science and Social Studies. The University of Ghana's undergraduate entry requirements page asks WASSCE applicants for credit passes (A1 to C6) in all four. Our WASSCE grading system guide explains the difference between credit and pass grades.

Step 1: turn the syllabus into a checklist

Take the syllabus and write every topic on one page. Group them in broad areas that most Core Mathematics courses include:

• Number and numeration: fractions, decimals, percentages, ratio and proportion, standard form, indices, logarithms and surds
• Algebra: simplification, factorisation, linear and quadratic equations, simultaneous equations, inequalities, variation
• Geometry and mensuration: angles, polygons, circles, perimeters, areas and volumes
• Trigonometry and bearings
• Statistics and probability: data presentation, mean, median, mode, probability
• Sets, relations and functions, and coordinate geometry

Confirm each against your syllabus, because content can change. Then mark each topic as green (confident), amber (shaky) or red (weak). Plan your revision around the reds first.

Step 2: study actively

Do, do not just read. Mathematics is learned with a pencil. For each topic:

1. Read a worked example once.
2. Close the book and solve a similar problem.
3. Check your solution, and write the exact step where you went wrong.
4. Redo the problem the next day.

Keep a formula sheet. One page per topic area, in your own handwriting. Writing helps memory, and you can glance at it daily.

Keep an error log. Every mistake goes in a notebook with a short note: careless slip, forgot a formula, misread the question, or did not understand the method. After two weeks you will see your pattern and can fix it.

Step 3: build exam skills

Practise timed sets. Choose a block of questions and give yourself a strict time limit. Time pressure is often what separates a B3 from a C6.

Show full working. In a theory question, write each step, include units and state the final answer clearly. If you slip on arithmetic, your working still shows what you understood.

Read the question twice. A common loss: finding the wrong quantity (for example the area when the question asks for the perimeter).

Check reasonableness. If a probability is greater than 1, or a length comes out negative, you have made an error.

Draw diagrams. For geometry, bearings, trigonometry and word problems, a quick diagram makes the question clearer and often reveals the method.

An original example to try

A trader in Kumasi buys 50 tubers of yam at GH¢8 each and sells 40 of them at GH¢9 each. She wants a total profit of GH¢60 on all 50 yams. At what price must she sell each of the remaining yams?

Work it out before reading on. Cost: 50 × 8 = GH¢400. Revenue needed: 400 + 60 = GH¢460. Revenue from the first 40 yams: 40 × 9 = GH¢360. The remaining 10 yams must bring in 460 - 360 = GH¢100, so each sells at GH¢10. Notice the habit that earns marks: write the cost, the target, the part already earned, and only then the unknown. Then check that GH¢10 is a sensible price.

Try writing your own two-step profit question with different numbers and solve it, which is a good way to learn.

Step 4: a weekly rhythm

• Monday to Thursday: one topic per evening, 45 minutes, including 10 questions.
• Friday: mixed revision of the week's topics, 30 minutes.
• Saturday: one timed set of mixed questions, then correct every error.
• Sunday: rest, or review your error log for 15 minutes.

In the final eight weeks before the exam, switch from learning new topics to timed full-paper practice. Our guides to how to solve maths faster and how to use past questions fit this stage well.

Handle anxiety

Many strong students lose marks to panic. If a question looks strange, breathe, write down what is given, and try the first small step. Our guide to beating exam anxiety has more.

Exam-week checklist

Pack two pens, two pencils, an eraser and a ruler, plus any instruments that WAEC allows for your paper, and check the rules for calculators and tables in your exam instructions. Read all the instructions on the paper before you start, plan how long you will spend on each section, and begin with a question you are sure about to build confidence. In the final five minutes, re-check arithmetic and make sure every question has an answer written clearly.

Mark the dates

A 2027 window has been reported in the press, but WAEC Ghana had not listed a timetable when we checked. See the WASSCE Ghana 2027 timetable page for the latest.

Practise WAEC-style questions

WASSCE questions are set by WAEC across West Africa, so practising WAEC-style questions is useful preparation. We do not claim that the papers are identical across countries, and ExamPadi does not yet have a Ghana-specific question bank. You can practise WAEC-style Mathematics free at ExamPadi WAEC Mathematics. Confirm exam dates, paper formats and rules on the official WAEC Ghana site (waecgh.org) and with your school; the sources used here are dated 2024 to 2026 and can change.
