Sample Bac E Bénin Practice Questions

Try these sample questions to test your Bac E Bénin exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the limit of f(x) = (x² − 9) / (x − 3) as x approaches 3?
A.0
B.3
C.6
D.Does not exist
Explanation: Factoring the numerator gives x² − 9 = (x − 3)(x + 3). For x ≠ 3, the expression simplifies to f(x) = x + 3. Taking the limit as x → 3 yields 3 + 3 = 6.
2Given the complex number z = 1 + i√3, what is its modulus |z| and principal argument arg(z)?
A.|z| = 2, arg(z) = π/3
B.|z| = 4, arg(z) = π/3
C.|z| = 2, arg(z) = π/6
D.|z| = √3, arg(z) = π/4
Explanation: The modulus is |z| = √(1² + (√3)²) = √(1 + 3) = √4 = 2. Factoring out 2 gives z = 2(1/2 + i√3/2). Since cos(θ) = 1/2 and sin(θ) = √3/2, the principal argument is θ = π/3 rad.
3What is the derivative of the real-valued function f(x) = ln(2x + 5) for x > −5/2?
A.1 / (2x + 5)
B.2 / (2x + 5)
C.2 / x
D.ln(2) / (2x + 5)
Explanation: Applying the chain rule for logarithmic functions (d/dx[ln(u)] = u'/u) where u(x) = 2x + 5 and u'(x) = 2 yields f'(x) = 2 / (2x + 5).
4Evaluate the definite integral I = ∫_0^2 (3x² − 2x + 1) dx.
A.4
B.6
C.8
D.10
Explanation: The antiderivative F(x) = x³ − x² + x. Evaluating between 0 and 2: F(2) = 2³ − 2² + 2 = 8 − 4 + 2 = 6, and F(0) = 0. Thus I = 6 − 0 = 6.
5A fair coin is tossed 3 times. What is the probability of obtaining exactly two heads?
A.1/8
B.3/8
C.1/2
D.5/8
Explanation: Using the binomial distribution with n = 3, k = 2, and p = 1/2: P(X = 2) = C(3, 2) × (1/2)² × (1/2)¹ = 3 × 1/8 = 3/8. The successful outcomes are {HHT, HTH, THH} out of 8 equally likely outcomes.
6In 3D space with an orthonormal coordinate system, compute the dot product of vectors u = (2, −1, 3) and v = (4, 2, −1).
A.3
B.9
C.−3
D.7
Explanation: The dot product is computed as u · v = x_u x_v + y_u y_v + z_u z_v = 2(4) + (−1)(2) + 3(−1) = 8 − 2 − 3 = 3.
7An arithmetic sequence (u_n) has first term u_0 = 4 and common difference d = 3. What is the sum S_5 = u_0 + u_1 + u_2 + u_3 + u_4 of the first 5 terms?
A.40
B.45
C.50
D.65
Explanation: The terms are u_0 = 4, u_1 = 7, u_2 = 10, u_3 = 13, u_4 = 16. Using the arithmetic series sum formula S_n = n × (u_0 + u_{n-1}) / 2: S_5 = 5 × (4 + 16) / 2 = 5 × 20 / 2 = 50.
8Find the particular solution to the first-order differential equation y' + 3y = 0 satisfying the initial condition y(0) = 5.
A.y(t) = 5 e^(3t)
B.y(t) = 5 e^(−3t)
C.y(t) = −3 e^(5t)
D.y(t) = e^(−3t) + 4
Explanation: The differential equation y' + ay = 0 has the general solution y(t) = C e^(−at). Here a = 3, so y(t) = C e^(−3t). Using the initial condition y(0) = 5 gives C e^0 = C = 5, yielding y(t) = 5 e^(−3t).
9Compute the complex power (1 + i)^8.
A.8
B.16
C.16i
D.−16
Explanation: In trigonometric form, 1 + i = √2 e^(iπ/4). Raising to the 8th power: (1 + i)^8 = (√2)^8 × [e^(iπ/4)]^8 = 2⁴ × e^(i2π) = 16 × 1 = 16.
10Evaluate the integral I = ∫_0^1 x e^x dx using integration by parts.
A.1
B.e − 1
C.e
D.2e − 1
Explanation: Let u = x (so du = dx) and dv = e^x dx (so v = e^x). By the integration by parts formula ∫ u dv = uv − ∫ v du: I = [x e^x]_0^1 − ∫_0^1 e^x dx = (1·e¹ − 0) − [e^x]_0^1 = e − (e − 1) = e − e + 1 = 1.

About the Bac E Bénin Exam

The Baccalauréat Série E (Mathématiques et Techniques) is Benin's mathematics-and-technology secondary school leaving diploma, organized by the Office du Baccalauréat du Bénin (OBB) under the Ministère de l'Enseignement Supérieur et de la Recherche Scientifique (MESRS). Taught at technical lycées such as the Lycée Technique Coulibaly in Cotonou, Série E combines advanced mathematics and physics with mechanical construction, resistance of materials (RDM), industrial drawing, and manufacturing technology. The official assessment is administered in French and is genuinely mixed: written problem sets and technical drawing papers, a compulsory five-hour Manipulation workshop practical carrying coefficient 3, and — for borderline candidates — a second-group oral in Philosophie, Anglais and Etude de Fabrication ou Technologie. This practice bank provides 100 English-language multiple-choice questions with worked calculations and engineering rationales. Because part of Série E is a hands-on workshop performance, these MCQs teach its underlying safety, sequencing, setup and interpretation but cannot certify the practical skill or simulate the oral.

Assessment

First group, per the OBB coefficient table for Série E: a compulsory Manipulation practical (Travaux Pratiques, coeff 3, 5h) plus written papers in Mathématiques (coeff 5, 4h), Sciences Physiques (coeff 4, 4h), Construction Mécanique (coeff 3, 5h), Etude de Fabrication ou Technologie (coeff 2, 2h) and Français (coeff 2, 4h) — Total 1 = 19 coefficients (380 points) — plus EPS (coeff 1) for 20 coefficients / 400 points. Philosophie and Anglais are NOT first-group written papers in Série E: they are assessed only in the compulsory second-group oral (Philosophie coeff 1, Anglais coeff 1, Etude de Fabrication ou Technologie coeff 2, Total 2 = 4 coefficients / 80 points), open to candidates averaging 9.00 to 9.99/20, for a 24-coefficient / 480-point final total. The 2026 session sat 15–18 June. This bank is an English-language MCQ study adaptation; it cannot substitute for the 5-hour workshop practical or the oral.

Bac E Bénin Study Tips from Top Performers

1Prioritise Mathématiques (coeff 5) and the technology cluster — Construction Mécanique (coeff 3), the Manipulation practical (coeff 3) and Etude de Fabrication ou Technologie (coeff 2+2) together outweigh any single subject.
2Work through full calculation steps in mechanics, RDM (bending moments, normal and shear stress) and gear-ratio kinematics rather than memorising formulas.
3Rehearse the Manipulation practical as a procedure: measurement and metrology, instrument setup, correct operation sequence, recording results and workshop safety — the MCQs here drill that reasoning, but you still need bench time.
4Prepare Philosophie and Anglais specifically for the second-group oral, where they are examined at coefficient 1 each; they are not first-group written papers in Série E.
5Practise manufacturing process planning and operation ordering for Etude de Fabrication ou Technologie, which is examined twice — written in the first group and orally in the second.

Frequently Asked Questions

What is the focus of the Baccalauréat Série E in Benin?

Série E (Mathématiques et Techniques) bridges advanced mathematics and physics with industrial engineering, mechanical construction, resistance of materials (RDM) and manufacturing technology. It prepares students for engineering faculties such as EPAC at the Université d'Abomey-Calavi and for polytechnic institutes.

Is the official Benin Baccalauréat Série E multiple choice?

No. The official assessment organised by the Office du Baccalauréat du Bénin (OBB) is conducted in French and combines written mathematical and physics problem sets, technical drawing and manufacturing-study papers, a compulsory five-hour Manipulation workshop practical, and a second-group oral for borderline candidates. This practice bank is an English-language MCQ study adaptation for conceptual mastery and self-assessment; it is not an official translation and does not simulate the practical or the oral.

Does Série E include a compulsory practical exam?

Yes. The OBB table lists a Manipulation (Travaux Pratiques) practical at coefficient 3 lasting five hours as part of the first group. It is a hands-on workshop and laboratory assessment and carries the same coefficient as Construction Mécanique, so it cannot be skipped or replaced by written work.

What is the passing score and grading system for Série E in Benin?

The examination is graded on a 0–20 scale and a candidate needs an overall weighted average (moyenne générale) of at least 10.00/20. Candidates averaging at least 9.00 and below 10.00 are declared admissible to the second-group oral, and the Baccalauréat is awarded if the combined first- and second-group average reaches 10.00/20. Benin's admissibility band is 9.00–9.99, not the 8.00–9.99 band used in France.

What are the subject coefficients in Série E?

First group: Mathématiques coeff 5 (4h), Sciences Physiques coeff 4 (4h), Construction Mécanique coeff 3 (5h), Manipulation practical coeff 3 (5h), Etude de Fabrication ou Technologie coeff 2 (2h), Français coeff 2 (4h) — 19 coefficients — plus EPS coeff 1, for 20. The second-group oral adds Philosophie (coeff 1), Anglais (coeff 1) and Etude de Fabrication ou Technologie (coeff 2), giving a 24-coefficient final total. Note that Philosophie and Anglais appear only in the oral.
