Sample NSSCO Mathematics (6131) Practice Questions

Try these sample questions to review concepts for the NSSCO Mathematics (6131) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following is a prime number?
A.51
B.57
C.61
D.63
Explanation: A prime has exactly two distinct positive factors: 1 and itself. 61 is prime. 51 = 3×17, 57 = 3×19, and 63 = 7×9.
2Find the highest common factor (HCF) of 24 and 36.
A.6
B.8
C.12
D.18
Explanation: 24 = 2³ × 3 and 36 = 2² × 3². HCF uses lowest common powers: 2² × 3 = 12.
3Find the lowest common multiple (LCM) of 8 and 12.
A.24
B.16
C.48
D.96
Explanation: 8 = 2³ and 12 = 2² × 3. LCM takes highest powers: 2³ × 3 = 24.
4Calculate 2/3 + 1/6.
A.1/2
B.5/6
C.3/9
D.1
Explanation: Common denominator 6: 2/3 = 4/6. Sum = 4/6 + 1/6 = 5/6.
5Express 0.45 as a percentage.
A.4.5%
B.45%
C.0.45%
D.450%
Explanation: Multiply the decimal by 100: 0.45 × 100 = 45%.
6Simplify √49.
A.7
B.24.5
C.14
D.√7
Explanation: 49 = 7², so √49 = 7.
7Write 3 500 000 in standard form.
A.3.5 × 10⁶
B.35 × 10⁵
C.3.5 × 10⁵
D.0.35 × 10⁷
Explanation: Standard form is A × 10ⁿ with 1 ≤ A < 10. 3 500 000 = 3.5 × 10⁶.
8If A = {1, 2, 3, 4} and B = {3, 4, 5}, what is A ∩ B?
A.{1, 2, 3, 4, 5}
B.{3, 4}
C.{1, 2}
D.{5}
Explanation: Intersection contains elements in both sets: 3 and 4.
9Convert 2.5 km to metres.
A.25 m
B.250 m
C.2500 m
D.25 000 m
Explanation: 1 km = 1000 m, so 2.5 km = 2500 m.
10Find the perimeter of a rectangle 8 cm by 5 cm.
A.13 cm
B.26 cm
C.40 cm
D.20 cm
Explanation: Perimeter = 2(l + w) = 2(8 + 5) = 26 cm.

NSSCO Mathematics (6131): Suggested Study Strategy

1Practise clear, step-by-step working for both short-answer and structured styles — Paper 2 rewards multi-step reasoning with diagrams and correct units.
2Keep a non-programmable scientific calculator ready and drill three-significant-figure rounding when the question does not specify accuracy.
3Memorise key formulae for mensuration, Pythagoras, SOHCAHTOA, and matrix operations; then practise applying them in worded Namibia-context problems.
4Balance algebra fluency (indices, equations, sequences) with geometry, bearings and statistics — all twelve syllabus topics can appear across both papers.
5For probability and sets, draw Venn diagrams or tree diagrams before computing; check that probabilities lie between 0 and 1.

Frequently Asked Questions

What is NSSCO Mathematics 6131?

Syllabus 6131 is the Namibia Senior Secondary Certificate Ordinary Level Mathematics syllabus published by NIED for Grades 10–11 and examined by DNEA. It covers twelve topic areas from numbers and algebra through geometry, mensuration, trigonometry, matrices, statistics and probability.

What is the paper structure for NSSCO Mathematics?

All candidates take two written papers with no choice of questions: Paper 1 short-answer (80 marks, 2 hours, 40%) and Paper 2 structured questions (120 marks, 3 hours, 60%), for a combined total of 200 marks. A non-programmable scientific calculator is required.

What grades are awarded for NSSCO Mathematics?

Results are reported on letter grades A–G (U = ungraded). The NIED syllabus does not publish a single numeric percentage pass mark; grade boundaries are set by the examining authority for each series.

Is a calculator allowed?

Yes. The syllabus prescribes that learners must have a non-programmable scientific electronic calculator for the papers. Unless accuracy is specified, answers should generally be given to three significant figures when not exact.

How much does NSSCO Mathematics entry cost?

A verified DNEA per-subject NSSCO entry fee was not confirmed from an official DNEA circular at the time this page was written. Confirm current fees with DNEA or your examination centre. Do not treat NAMCOL tuition or course fees as the examination entry fee.

Are these official DNEA examination questions?

No. Official NSSCO Mathematics uses written short-answer and structured papers, not multiple-choice only. This bank is an original English-language MCQ study adaptation covering topics from syllabus 6131 content for practice of number, algebra, geometry, mensuration, trigonometry, statistics and related topics.
