NECO 2025 Further Mathematics Exam Breakdown for July 24, 2025
Exam Structure and Time
The NECO Further Mathematics paper is divided into two parts:
- Paper III: Objective Paper – Time: 10:00 am to 12:00 noon (2 hours)
- Paper II: Essay Paper – Time: 12:00 noon to 2:30 pm (2 hours 30 minutes)
Each paper covers a broad range of advanced mathematical topics, so candidates are advised to revise thoroughly and manage their time effectively during the examination.
Major Areas to Focus On
The NECO Further Mathematics syllabus covers five core areas:
1. Algebra and Matrices
- Solution of quadratic equations using factorization, completing the square, and quadratic formula
- Algebraic manipulation involving expressions, surds, and indices
- Expansion and simplification using the binomial theorem (including fractional and negative indices)
- Formation and solution of simultaneous and linear inequalities
- Matrix operations: addition, subtraction, multiplication, inverse of a 2×2 matrix
- Determinants and their application in solving simultaneous equations
2. Trigonometry
- Angle measurement in degrees and radians and conversion between both
- Trigonometric ratios and exact values of sin, cos, and tan for special angles (30°, 45°, 60°, 90°, etc.)
- Graphs of trigonometric functions and interpretation of amplitude, frequency, and phase
- Use of identities such as sin²θ + cos²θ = 1, tanθ = sinθ/cosθ, etc.
- Solving trigonometric equations and applying trigonometry to solve problems involving angles of elevation and depression
- Use of sine rule, cosine rule, and area of triangle formula involving sine
3. Calculus
- Understanding the concept of limits, continuity, and differentiation
- Differentiation of algebraic functions using standard rules (power rule, product rule, quotient rule, chain rule)
- Applications of differentiation to find gradient, equations of tangents and normals, turning points, and rates of change
- Integration of algebraic functions and application to area under curve and volume of revolution
- Solving simple first-order differential equations (separable variables)
4. Coordinate Geometry
- Cartesian coordinate system and graphing
- Finding distance between two points, midpoint of a line segment, and slope of a line
- Equation of a straight line in the form y = mx + c and general form ax + by + c = 0
- Angle between two lines and conditions for perpendicularity and parallelism
- Equation and properties of a circle, parabola, ellipse, and hyperbola
- Graphical representation of conic sections
5. Statistics and Probability
- Data collection, representation (bar charts, pie charts, histograms), and interpretation
- Measures of central tendency: mean, median, and mode
- Measures of dispersion: range, variance, and standard deviation
- Concept of probability, events, sample space, and simple probability problems
- Use of permutations and combinations in probability
- Set theory and Venn diagram analysis (union, intersection, complement, etc.)
Additional Information to Guide Your Preparation
Recommended Revision Strategy
- Review Key Formulas: Ensure you memorize and understand formulas for trigonometric identities, differentiation and integration, coordinate geometry equations, and probability computations.
- Solve Past Questions: Practice both objective and essay-style questions from previous NECO papers to get used to the pattern and difficulty.
- Time Management: Allocate time wisely during the exam. Spend no more than 2 minutes per question in the objective paper, and divide your essay time proportionally.
- Work Neatly and Show All Steps: In the essay paper, always show your workings clearly. Even if your final answer is wrong, you can still gain method marks.
- Use the Correct Calculator: Only bring non-programmable scientific calculators. Make sure you are familiar with its functions before the exam day.
On the Day of the Exam
- Arrive at the exam venue early (at least 30 minutes before start time)
- Bring all necessary materials: your exam slip, HB pencils, erasers, ruler, sharpener, and calculator
- Stay hydrated and have a light breakfast before the exam
- Remain calm and confident; start with the questions you understand best

Final Reminders
- Understand the logic behind concepts, not just the formulas
- Pay special attention to word problems that require translation into mathematical expressions
- For questions involving graphs or geometry, be sure your diagrams are labeled and accurate
- Carefully read each question before attempting to solve it
- Check your answers if time permits, especially in the objective section
