Sample Cameroon GCE O-Level Mathematics Practice Questions

Try these sample questions to test your Cameroon GCE O-Level Mathematics exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1If universal set $\mathcal{E} = \{x : x \in \mathbb{Z}^+, 1 \le x \le 10\}$, set $A = \{2, 3, 5, 7\}$, and set $B = \{1, 3, 5, 7, 9\}$, find $n(A \cap B)$.

A.2

B.3

C.4

D.5

Explanation: The intersection $A \cap B$ consists of elements common to both $A$ and $B$: $A \cap B = \{3, 5, 7\}$. Therefore, the number of elements $n(A \cap B) = 3$.

2Evaluate $\left(\frac{8}{27}\right)^{-\frac{2}{3}}$.

A.$\frac{4}{9}$

B.$\frac{9}{4}$

C.$\frac{2}{3}$

D.$\frac{3}{2}$

Explanation: Apply negative and fractional index laws: $\left(\frac{8}{27}\right)^{-\frac{2}{3}} = \left(\frac{27}{8}\right)^{\frac{2}{3}} = \left(\sqrt[3]{\frac{27}{8}}\right)^2 = \left(\frac{3}{2}\right)^2 = \frac{9}{4}$.

3Simplify $\log_{10} 25 + \log_{10} 4 - \log_{10} 10$.

A.0

B.1

C.2

D.10

Explanation: Using logarithm rules: $\log_{10} 25 + \log_{10} 4 - \log_{10} 10 = \log_{10}\left(\frac{25 \times 4}{10}\right) = \log_{10}\left(\frac{100}{10}\right) = \log_{10} 10 = 1$.

4Solve the linear equation: $\frac{2x - 3}{4} - \frac{x - 1}{3} = 1$.

A.$x = \frac{17}{2}$

B.$x = \frac{13}{2}$

C.$x = 17$

D.$x = 7$

Explanation: Multiply each term by the LCM of the denominators (12): $3(2x - 3) - 4(x - 1) = 12 \implies 6x - 9 - 4x + 4 = 12 \implies 2x - 5 = 12 \implies 2x = 17 \implies x = \frac{17}{2}$.

5Solve the quadratic equation $2x^2 - 5x - 3 = 0$.

A.$x = 3$ or $x = -\frac{1}{2}$

B.$x = -3$ or $x = \frac{1}{2}$

C.$x = 2$ or $x = -\frac{3}{2}$

D.$x = -2$ or $x = \frac{3}{2}$

Explanation: Factorize $2x^2 - 5x - 3 = 0$: Find factors of $2 \times (-3) = -6$ that sum to $-5$, which are $-6$ and $+1$. Thus, $2x^2 - 6x + x - 3 = 0 \implies 2x(x - 3) + 1(x - 3) = 0 \implies (2x + 1)(x - 3) = 0$. Hence, $x = 3$ or $x = -\frac{1}{2}$.

6Find the gradient (slope) of the straight line passing through the points $A(-2, 3)$ and $B(4, -9)$.

A.$-2$

B.$2$

C.$-\frac{1}{2}$

D.$\frac{1}{2}$

Explanation: The gradient $m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-9 - 3}{4 - (-2)} = \frac{-12}{4 + 2} = \frac{-12}{6} = -2$.

7What is the sum of the interior angles of a regular polygon with 8 sides (an octagon)?

A.$720^\circ$

B.$900^\circ$

C.$1080^\circ$

D.$1260^\circ$

Explanation: The formula for the sum of interior angles of an $n$-sided polygon is $(n - 2) \times 180^\circ$. For an octagon ($n = 8$): $(8 - 2) \times 180^\circ = 6 \times 180^\circ = 1080^\circ$.

8In a right-angled triangle $ABC$, the hypotenuse $AC = 13\text{ cm}$ and side $AB = 5\text{ cm}$. Find the length of side $BC$.

A.$8\text{ cm}$

B.$10\text{ cm}$

C.$12\text{ cm}$

D.$14\text{ cm}$

Explanation: By Pythagoras' theorem: $AC^2 = AB^2 + BC^2 \implies 13^2 = 5^2 + BC^2 \implies 169 = 25 + BC^2 \implies BC^2 = 144 \implies BC = \sqrt{144} = 12\text{ cm}$.

9Calculate the total surface area of a closed solid cylinder of radius $r = 7\text{ cm}$ and height $h = 10\text{ cm}$. (Take $\pi = \frac{22}{7}$)

A.$440\text{ cm}^2$

B.$594\text{ cm}^2$

C.$748\text{ cm}^2$

D.$1540\text{ cm}^2$

Explanation: The total surface area of a closed cylinder is $A = 2\pi r h + 2\pi r^2 = 2\pi r(h + r) = 2 \times \frac{22}{7} \times 7 \times (10 + 7) = 44 \times 17 = 748\text{ cm}^2$.

10Given the matrix $M = \begin{pmatrix} 4 & 2 \\ 3 & 1 \end{pmatrix}$, calculate the determinant $\det(M)$.

A.$-2$

B.$2$

C.$-10$

D.$10$

Explanation: For a $2 \times 2$ matrix $\begin{pmatrix} a & b \\ c & d \end{pmatrix}$, $\det(M) = ad - bc = (4)(1) - (2)(3) = 4 - 6 = -2$.

About the Cameroon GCE O-Level Mathematics Exam

The Cameroon General Certificate of Education (GCE) Ordinary Level Mathematics (Subject Code 0570) is a compulsory national terminal secondary school examination administered annually by the Cameroon GCE Board (CGCEB) in Buea, South-West Region, Cameroon. Taken by all secondary school Form 5 students, the syllabus delivers essential mathematical competencies spanning numerical arithmetic, algebraic manipulation, Euclidean and coordinate geometry, trigonometry, mensuration, vectors, matrices, statistics, and probability. The examination is organized into two papers: Paper 1 contains 50 compulsory multiple-choice questions (1 hour 30 minutes) and carries 40% of the subject mark; Paper 2 (2 hours 30 minutes) carries the remaining 60% and is split into Section A, ten structural questions, and Section B, four essay-type questions, with every question compulsory. Achieving at least a Grade C in Mathematics is a universal requirement for secondary school graduation, admission into high school Sixth Form combinations (both Science and Arts), and subsequent entry into all tertiary academic and professional institutions in Cameroon. Format note: this site's practice bank contains 100 four-option multiple-choice questions covering the entire official syllabus. Paper 1 of the real examination is genuinely multiple choice (50 compulsory questions), so the format matches that paper, but the bank is a study aid only — it does not simulate the written structured paper, and its length does not describe the official exam.

Cameroon GCE O-Level Mathematics Study Tips from Top Performers

1Master Step-by-Step Algebraic Factorization: Ensure fluency in factoring quadratic trinomials ($ax^2 + bx + c$), differences of two squares ($a^2 - b^2$), and algebraic fractions before attempting simultaneous equations.

2Memorize Circle Theorem Rules: Be prepared to justify geometric angles by citing exact theorems (e.g., angle at center is twice angle at circumference, angles in the same segment are equal, opposite angles of a cyclic quadrilateral sum to $180^\circ$).

3Practice Three-Figure Bearings and Trigonometry: Always sketch clear diagrams with North arrows marked at every referenced point, and know when to apply right-angled ratios versus the Sine Rule or Cosine Rule.

4Be Fluent in Matrix Determinants and Inverses: For a $2 \times 2$ matrix $\begin{pmatrix} a & b \\ c & d \end{pmatrix}$, compute the determinant $\Delta = ad - bc$ and inverse $\frac{1}{\Delta}\begin{pmatrix} d & -b \\ -c & a \end{pmatrix}$ accurately.

5Work With Statistics and Cumulative Frequency Curves: Practice reading medians, lower quartiles ($Q_1$), upper quartiles ($Q_3$), and percentiles directly from ogives.

Frequently Asked Questions

What is the Cameroon GCE Ordinary Level Mathematics (Subject Code 0570)?

The Cameroon GCE O-Level Mathematics (0570) is a compulsory national secondary school leaving examination administered by the Cameroon GCE Board (CGCEB) in Buea for Form 5 candidates. It assesses core mathematical knowledge and problem-solving skills across algebra, geometry, trigonometry, vectors, matrices, and statistics.

How is the 0570 Mathematics examination structured?

Mathematics 0570 is a two-paper subject: Paper 1 consists of 50 compulsory multiple-choice questions (1 hour 30 minutes) covering the entire syllabus and is weighted at 40%. Paper 2 (2 hours 30 minutes) is weighted at 60% and requires detailed working: Section A sets ten structural questions and Section B four essay-type questions, all compulsory.

What grading scale is used for Cameroon GCE Ordinary Level subjects?

The Cameroon GCE Board reports Ordinary Level results on the letter scale A, B, C, D, E and U. Grades A, B and C are the passes counted in the Board's own Performance by Subjects statistics; D and E are fails and U is ungraded. The Board does not publish the percentage mark ranges behind these grades.

What are the registration fees for GCE O-Level Mathematics in Cameroon?

The Cameroon GCE Board publishes Ordinary Level fees as an 8,000 FCFA registration fee, a 1,000 FCFA fee per subject, and 1,000 FCFA for franking of form G3 — so an Ordinary Level entry costs 8,000 + 1,000 + 1,000 FCFA plus a further 1,000 FCFA for each additional subject. The Board requires candidates to offer at least six subjects, which must include English Language, French and Mathematics, so Mathematics cannot be entered on its own; the registration and franking fees are paid once whatever the number of subjects. A further 5,000 FCFA practical fee applies only to the subjects that have a practical paper, which Mathematics does not.

Are calculators and mathematical tables permitted in the examination?

Candidates are permitted to use non-programmable electronic calculators and official four-figure mathematical tables (SMP or CGCEB approved tables) along with standard geometrical sets (ruler, compass, protractor, set squares).
