Sample EAMAC Concours EAC Practice Questions

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

1In the multiplicative group (Z/7Z)* of non-zero residues modulo 7, what is the order of the element 2?
A.2
B.3
C.7
D.6
Explanation: The order is the smallest k ≥ 1 with 2^k ≡ 1 (mod 7). Successive powers give 2^1 = 2, 2^2 = 4 and 2^3 = 8 ≡ 1 (mod 7), so the order of 2 is 3. As Lagrange's theorem requires, 3 divides the group order 6.
2A finite group G has order 12. By Lagrange's theorem, which of the following cannot be the order of a subgroup of G?
A.5
B.3
C.4
D.6
Explanation: Lagrange's theorem states that the order of any subgroup of a finite group divides the order of the group. The divisors of 12 are 1, 2, 3, 4, 6 and 12. Since 5 does not divide 12, no subgroup of G can have order 5.
3In the ring Z/12Z, which of the following classes is a zero divisor?
A.The class of 11
B.The class of 4
C.The class of 5
D.The class of 7
Explanation: A non-zero class a is a zero divisor if a·b ≡ 0 (mod 12) for some non-zero class b. Here 4 × 3 = 12 ≡ 0 (mod 12), so 4 is a zero divisor. In Z/nZ the zero divisors are exactly the non-zero classes not coprime to n, and gcd(4, 12) = 4.
4What is the sum of the five complex fifth roots of unity, 1 + ω + ω^2 + ω^3 + ω^4 with ω = e^(2iπ/5)?
A.5
B.0
C.-1
D.1
Explanation: Since ω ≠ 1, the geometric sum is (1 - ω^5)/(1 - ω) = (1 - 1)/(1 - ω) = 0. Equivalently, the n-th roots of unity are the roots of X^n - 1, whose X^(n-1) coefficient is 0, so their sum is 0 for any n ≥ 2.
5What are the solutions in C of the equation z^2 - 2z + 5 = 0?
A.z = 1 + 2i and z = 1 - 2i
B.z = -1 + 2i and z = -1 - 2i
C.z = 2 + i and z = 2 - i
D.z = 1 + 4i and z = 1 - 4i
Explanation: The discriminant is Δ = (-2)^2 - 4 × 1 × 5 = 4 - 20 = -16 = (4i)^2. The roots are z = (2 ± 4i)/2 = 1 ± 2i. Check: their sum is 2 and their product is 1 + 4 = 5, matching the coefficients.
6What is the remainder of the Euclidean division of P(X) = X^5 + X + 1 by X^2 + 1 in R[X]?
A.2X + 1
B.2X - 1
C.X + 1
D.1
Explanation: Work modulo X^2 + 1, where X^2 ≡ -1. Then X^4 = (X^2)^2 ≡ 1 and X^5 = X·X^4 ≡ X. Hence P(X) ≡ X + X + 1 = 2X + 1. This has degree less than 2, so it is the remainder. Check with X = i: P(i) = i^5 + i + 1 = 2i + 1.
7In a radar data processing system, coordinates are rotated by an angle theta = 90 degrees counterclockwise. What is the standard 2x2 rotation matrix R(90 deg)?
A.[[1, 0], [0, 1]]
B.[[-1, 0], [0, -1]]
C.[[0, 1], [-1, 0]]
D.[[0, -1], [1, 0]]
Explanation: The 2D rotation matrix is [[cos(theta), -sin(theta)], [sin(theta), cos(theta)]]. For theta = 90 degrees, cos(90 deg) = 0 and sin(90 deg) = 1, resulting in [[0, -1], [1, 0]].
8What is the multiplicity of the root 1 of the polynomial P(X) = X^3 - 3X + 2?
A.0
B.3
C.2
D.1
Explanation: P(1) = 1 - 3 + 2 = 0. P'(X) = 3X^2 - 3 gives P'(1) = 0. P''(X) = 6X gives P''(1) = 6 ≠ 0. The root 1 therefore has multiplicity exactly 2, and indeed P(X) = (X - 1)^2 (X + 2).
9What is the partial-fraction decomposition of F(X) = 1 / (X(X + 1)) over R?
A.1/X + 1/(X + 1)
B.1/X - 1/(X + 1)
C.-1/X + 1/(X + 1)
D.1/(X + 1) - 1/X^2
Explanation: Write 1/(X(X + 1)) = a/X + b/(X + 1). Multiplying by X and setting X = 0 gives a = 1. Multiplying by X + 1 and setting X = -1 gives b = 1/(-1) = -1. So F = 1/X - 1/(X + 1). Check: (X + 1 - X)/(X(X + 1)) = 1/(X(X + 1)).
10The rational fraction (2X + 3) / ((X - 1)(X + 2)) is written as a/(X - 1) + b/(X + 2). What are a and b?
A.a = 5 and b = 1
B.a = 5/3 and b = 1/3
C.a = 5/3 and b = -1/3
D.a = 1/3 and b = 5/3
Explanation: Cover-up method: multiply by (X - 1) and set X = 1, giving a = (2 + 3)/(1 + 2) = 5/3. Multiply by (X + 2) and set X = -2, giving b = (-4 + 3)/(-2 - 1) = 1/3. Check: a + b = 2 matches the X coefficient of the numerator.

EAMAC Concours EAC: Suggested Study Strategy

1Work through EAMAC's past EAC and Ingénieur papers (annales) under timed 4-hour conditions; the 2024 papers covered series, Taylor expansions, partial fractions, Frenet kinematics, Ampère's theorem and plane electromagnetic waves.
2Prioritise mathematics and physics (coefficient 5 each) and avoid any mark below 7/20 in either, which is eliminatory.
3Revise the algebra topics often skipped in L2 courses: groups, rings, polynomials, rational fractions and Cayley–Hamilton.
4For French, practise explaining words in context and writing argued paragraphs with precise examples.
5For English, practise the official paper parts: five comprehension questions, 20 grammar items, translation into English and French, and a 200-word essay.

Frequently Asked Questions

Is the EAMAC EAC concours a multiple-choice exam?

No. The four papers are written: mathematics and physics exercises, a French text-analysis paper with an argued answer, and an English paper with comprehension, 20 grammar items, translation both ways and a short essay. This bank is an independent English-language MCQ study adaptation. It helps you revise concepts and calculations, but it is not an official translation and does not reproduce the written format.

Which papers carry the most weight?

In the 2026 notice, mathematics and physics each carry coefficient 5 (4 hours each), French coefficient 3 (4 hours) and English coefficient 2 (2 hours). A mark below 7/20 in mathematics or physics, or below 5/20 in French or English, eliminates the candidate.

Who can apply for the EAC cycle?

Students who have validated the second year of a scientific (DEUG, DUES, L2, CPGE) or technical (BTS, DUT, DTS) programme with strong mathematics and physics, and who are under 27 on 1 January 2026. ASECNA agents and civil aviation or meteorology professionals may apply up to age 45. A candidate cannot apply in the same year for both the concours and admission on qualifications (admission sur titre).

In which countries was the EAC cycle open in 2026?

EAMAC's 2026 table of open cycles lists the EAC cycle as open in Benin, Burkina Faso, the Central African Republic, Comoros, Gabon, Madagascar, Mali, Niger, Senegal, Chad and Togo. Registration ran online from 9 to 27 March 2026, and shortlisted candidates lodged their file with their civil aviation authority from 9 to 30 April 2026.
