Sample UNB IDR Entrance Practice Questions

Try these sample questions to review concepts for the UNB IDR Entrance exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1For the polynomial used to model a short growth pulse, f(x) = 4x³ − 6x + 1, what is the derivative f'(x)?

A.12x² − 6

B.12x³ − 6

C.4x² − 6

D.12x² + 1

Explanation: Differentiate term by term: the derivative of 4x³ is 12x², the derivative of −6x is −6, and the constant 1 vanishes. So f'(x) = 12x² − 6. This power rule is the starting tool for rates in the Mathématiques paper.

2Evaluate the definite integral ∫ from 0 to 2 of (3x² + 2) dx.

A.8

B.6

C.12

D.14

Explanation: An antiderivative of 3x² + 2 is x³ + 2x. Evaluating from 0 to 2 gives (8 + 4) − (0) = 12. Definite integrals of this type compute net accumulation (area, biomass increment, or dose) over an interval.

3What is log₁₀(0.01)?

A.2

B.−2

C.0.01

D.−100

Explanation: 0.01 = 10^{−2}, so log₁₀(0.01) = −2 by definition of the common logarithm. The same log scale appears in pH = −log₁₀[H⁺] in biochemistry contexts.

4Five seedlings have dry masses 12, 15, 18, 21 and 24 g. What is the arithmetic mean mass?

A.15 g

B.16 g

C.18 g

D.21 g

Explanation: The arithmetic mean is the sum divided by the count: (12+15+18+21+24)/5 = 90/5 = 18 g. For equally spaced data the mean equals the median, here the middle value 18 g.

5An arithmetic sequence of weekly counts begins at 5 and increases by 3 each week. What is the 8th term?

A.24

B.29

C.21

D.26

Explanation: The nth term of an arithmetic sequence is a_n = a_1 + (n−1)d. Here a_8 = 5 + 7×3 = 5 + 21 = 26. There are seven common differences between the first and the eighth term.

6Compute the determinant of the 2×2 matrix [[3, 1], [4, 2]].

A.2

B.10

C.8

D.−1

Explanation: For [[a, b], [c, d]] the determinant is ad − bc. Here 3×2 − 1×4 = 6 − 4 = 2. A non-zero determinant means the matrix is invertible and the corresponding linear system has a unique solution.

7Using the inverse relationship between ln and the exponential, simplify ln(e⁵).

A.e⁵

B.5

C.ln 5

D.5e

Explanation: The natural logarithm is the inverse of the exponential: ln(e^u) = u for every real u, so ln(e⁵) = 5. This cancellation is used constantly when linearising exponential growth or decay by taking ln.

8In a field plot, 40% of independent bacterial isolates carry a resistance plasmid. What is the probability that two independently sampled isolates both carry the plasmid?

A.0.80

B.0.40

C.0.16

D.0.08

Explanation: Independence lets probabilities multiply: P(both) = 0.40 × 0.40 = 0.16. Adding instead of multiplying would describe a mutually exclusive union, which this joint event is not.

9Let f(x) = x² ln x for x > 0. What is f'(x)?

A.2x ln x

B.x + 2 ln x

C.2 ln x + x²

D.2x ln x + x

Explanation: The product rule gives (u v)' = u' v + u v' with u = x² and v = ln x. Then u' = 2x and v' = 1/x, so f'(x) = 2x ln x + x² · (1/x) = 2x ln x + x. Factoring x(2 ln x + 1) is equivalent.

10If f(x) = e^{3x²}, what is f'(x)?

A.6x e^{3x²}

B.3x² e^{3x²}

C.e^{3x²}

D.6x² e^{3x²}

Explanation: The chain rule says d/dx e^{g(x)} = g'(x) e^{g(x)}. Here g(x) = 3x², so g'(x) = 6x and f'(x) = 6x e^{3x²}. Exponential growth or Gaussian kernels in biology are differentiated this way.

About the UNB IDR Entrance Exam

The IDR concours is a post-BAC+2 competitive written entrance exam for first-year admission to Université Nazi Boni's Institut du Développement Rural in Bobo-Dioulasso. Communiqué n°2026 00000008 MESRI/SG/UNB/P (22 July 2026) opens 60 places across agronomy, livestock, environment/water-and-forests, rural sociology and economics, and agricultural extension, and names four Licence 2 written papers: animal physiology, plant physiology, mathematics, and structural biochemistry and enzymology. Applications run on CampusFaso from 27 July to 10 September 2026 (23:59 UTC). Official papers are written in French. This free English MCQ bank trains the four named papers — it is not an official translation or a substitute for the written concours.

UNB IDR Entrance: Suggested Study Strategy

1Pitch revision at Licence 2: enzyme kinetics, water relations, and organ-system physiology, not lycée recall.

2For mathematics, practise genuine calculations (functions, statistics, rates) under a 3-hour paper timing.

3Learn Michaelis–Menten and Lineweaver–Burk plots with worked Km and Vmax numbers.

4Re-read the current UNB communiqué before applying — place counts and the dossier fee change by intake.

Frequently Asked Questions

Is this a school-leaving exam?

No. Eligibility is BAC+2 in Biology or an equivalent diploma. The papers follow the Licence 2 programme, not lycée Bac D depth.

Are the official papers multiple choice or in English?

No. The four named papers are written in French. This bank is an English-language MCQ study adaptation, not an official translation or a written-paper simulation.

Does admission include a scholarship?

The 22 July 2026 communiqué states that admission to the concours does not automatically confer a higher-education scholarship (bourse).
