Introduction
Mathematics is a compulsory subject for all candidates writing the NECO Senior Secondary Certificate Examination (SSCE). It forms a critical foundation for various academic and career paths, including science, engineering, social sciences, business, and education. The NECO Mathematics exam tests candidates’ ability to solve numerical, algebraic, geometrical, and statistical problems accurately and logically.
This guide provides a full overview of the 2025 NECO Mathematics exam structure, timetable, topics to study, and how to prepare effectively for success.
NECO Mathematics 2025 Timetable
According to the official NECO June/July 2025 timetable:
- Papers III & II – Objective and Essay (Theory)
- Date: Thursday, July 11, 2025
- Time: 10:00 am – 1:00 pm
- Duration: 3 hours
Mathematics has no practical component. Both the objective and essay papers are written on the same day, back-to-back.
Structure and Format of the Exam
The NECO Mathematics exam is divided into two papers written on the same day:
Paper III – Objective (50 Marks, 1 Hour)
- Consists of 50 multiple-choice questions
- Covers all core topics in the syllabus
- Tests speed, accuracy, and breadth of knowledge
Paper II – Essay/Theory (100 Marks, 2 Hours)
- Usually contains 10 structured questions, each with multiple sub-parts
- Candidates are expected to answer any five questions
- Tests deep understanding, method application, and correct use of mathematical procedures
Core Topics in the NECO Mathematics Syllabus
The syllabus is grouped into five major areas:
1. Number and Numeration

- Factorization and expansion
- Word problems and inequalities
- Variation and simple sequences
3. Geometry and Trigonometry
- Angles and lines, polygons, and circles
- Pythagoras’ theorem
- Plane shapes and their properties
- Bearings and distances
- Trigonometric ratios (sine, cosine, tangent)
4. Mensuration
- Perimeter, area, and volume of plane and solid shapes
- Surface areas of cubes, cylinders, cones, and spheres
- Conversions between units (length, area, volume)
5. Statistics and Probability
- Data collection and representation (bar charts, histograms, pie charts)
- Mean, median, and mode
- Probability of events
- Cumulative frequency and simple interpretation
Materials and Tools Allowed
- Mathematical set (ruler, compass, protractor, set squares)
- Non-programmable scientific calculator

Note: Programmable calculators and mobile devices are not allowed.
Tips for Success in NECO Mathematics
- Practice Past Questions
Solve at least 5–10 years of past NECO and WAEC Mathematics papers to familiarize yourself with question patterns. - Master Speed and Accuracy
For Paper III (Objective), timing is key. Train to answer all 50 questions within 1 hour. - Show All Working in Theory Section
In Paper II, marks are awarded for steps and procedures, not just final answers. - Focus on Weak Areas
Identify your weak topics (e.g., word problems, geometry, or trigonometry) and work on them using textbooks and video tutorials. - Revise with a Formula Sheet
Create a summary sheet of important formulas in algebra, geometry, and statistics for regular review. - Understand Instructions and Diagrams
Carefully read each question, especially those involving graphs or constructions. - Group Study and Peer Teaching
Explaining a concept to a classmate can help you understand it better.
Sample Theory Questions
- Solve the quadratic equation:
x2 – 5x + 6 = 0 - A man shares ₦15,000 between his two sons in the ratio 3:2. How much does each receive?
- A cone has a base radius of 3 cm and a height of 4 cm. Calculate its volume.
Use π=22/7 - Find the mean, median, and mode of the following data:
5, 7, 7, 8, 9, 10, 10, 10, 11 - A straight line passes through the points (2, 3) and (4, 7). Find its gradient and equation.
