WAEC GCE Mathematics 2026 Revision Guide is designed to help candidates prepare systematically for the West African Examinations Council (WAEC) General Mathematics examination. It covers the major topics, important formulas, examination format and key areas contained in the official Mathematics (Core)/General Mathematics syllabus.
The WAEC syllabus explains that the examination is designed to test candidates’ computational skills, understanding of mathematical concepts and their applications, ability to translate problems into mathematical language, accuracy and logical thinking.
Therefore, candidates preparing for the 2026 WAEC GCE Mathematics examination should not rely only on memorising formulas. You should also understand how to apply the formulas to calculations, word problems, graphs, geometry, statistics and other practical situations.
In this guide, you will find the WAEC GCE Mathematics 2026 topics, important formulas, areas to revise, examination format, revision checklist and preparation tips.

WAEC GCE Mathematics 2026 Examination Format
According to the WAEC Mathematics (Core)/General Mathematics syllabus, candidates are required to take two papers: Paper 1 and Paper 2. Both papers must be taken.
Paper 1
- Duration: 1½ hours
- Contains 50 multiple-choice questions.
- Carries 50 marks.
- The questions test the syllabus except sections marked with an asterisk.
- Candidates are expected to answer all the questions.
Paper 2
- Duration: 2½ hours.
- Carries 100 marks.
- Part I carries 40 marks and contains five compulsory elementary questions.
- Part II carries 60 marks and contains ten longer and more difficult questions.
- Candidates are expected to answer any five questions in Part II.
The syllabus also states that questions from sections marked with an asterisk are tested only as options in Part II of Paper 2. Candidates should therefore pay attention to the symbols used in the syllabus when planning their revision.
