LGCSE Mathematics 0178 is assessed in the October/November series through two written papers per tier: Core (Papers 1 & 3; grades C–G) or Extended (Papers 2 & 4; grades A*–G). Papers 1 and 2 ban calculators; Papers 3 and 4 require a non-programmable scientific calculator. The 100 questions on this page are an English-language MCQ study adaptation, not an official ECoL paper simulation.

Sample LGCSE Mathematics (0178) Practice Questions

Try these sample questions to test your LGCSE Mathematics (0178) exam readiness. 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.59

D.63

Explanation: A prime number has exactly two distinct positive factors: 1 and itself. 59 is only divisible by 1 and 59. 51 = 3×17, 57 = 3×19, and 63 = 7×9, so all three are composite.

2Find the highest common factor (HCF) of 36 and 54.

A.6

B.9

C.18

D.12

Explanation: 36 = 2² × 3² and 54 = 2 × 3³. The HCF uses the lowest powers of common primes: 2¹ × 3² = 18.

3Find the lowest common multiple (LCM) of 12 and 18.

A.36

B.6

C.72

D.54

Explanation: 12 = 2² × 3 and 18 = 2 × 3². The LCM takes the highest powers: 2² × 3² = 36.

4Calculate 3/4 + 2/5.

A.5/9

B.23/20

C.6/20

D.1

Explanation: Common denominator 20: 3/4 = 15/20 and 2/5 = 8/20. Sum = 23/20.

5Convert 0.375 to a fraction in lowest terms.

A.3/8

B.375/1000

C.3/5

D.37/100

Explanation: 0.375 = 375/1000. Divide numerator and denominator by 125: 3/8.

6Write 0.00056 in standard form.

A.5.6 × 10^-4

B.5.6 × 10^-3

C.56 × 10^-5

D.5.6 × 10^4

Explanation: Standard form is A × 10^n with 1 ≤ A < 10. Moving the decimal four places right gives 5.6, so 5.6 × 10^-4.

7Calculate 2^3 × 2^4.

A.2^7

B.2^12

C.4^7

D.2^1

Explanation: When multiplying powers with the same base, add the indices: 2^(3+4) = 2^7.

8Evaluate 5^-2.

A.1/25

B.-25

C.-1/25

D.25

Explanation: A negative index means reciprocal: 5^-2 = 1/5^2 = 1/25.

9A jacket costs M400. In a sale it is reduced by 15%. What is the sale price?

A.M340

B.M360

C.M385

D.M60

Explanation: 15% of 400 = 0.15 × 400 = 60. Sale price = 400 − 60 = M340. Equivalently, 85% of 400 = 0.85 × 400 = 340.

10Express 3:12 in its simplest form.

A.1:4

B.3:4

C.1:3

D.4:1

Explanation: Divide both parts by their HCF 3: 3÷3 : 12÷3 = 1:4.

LGCSE Mathematics (0178) Study Tips from Top Performers

1Drill non-calculator arithmetic and algebraic manipulation for Papers 1 and 2 — sign errors and order-of-operations mistakes cost easy marks.

2Memorise key formulae (area, volume, Pythagoras, SOHCAHTOA, sector and arc formulae) and practise showing four-figure working before three-figure final answers on calculator papers.

3Balance Core topics (strong number and space weightings) with Extended algebra emphasis if you aim for A*–B grades.

4Practise bearings, scale drawings, loci language, and multi-step mensuration with units consistent throughout.

5For statistics, always state whether you mean estimated mean from midpoints of groups, and check probability answers lie between 0 and 1.

Frequently Asked Questions

What is LGCSE Mathematics 0178?

Syllabus 0178 is the Examinations Council of Lesotho (ECoL) Mathematics syllabus for the Lesotho General Certificate of Secondary Education. It is a senior secondary qualification developed with the National Curriculum Development Centre (NCDC) and adopted from IGCSE Mathematics (0580), offered at Core and Extended levels.

What is the paper structure for LGCSE Mathematics?

Core candidates sit Paper 1 (short answer, 1 hour, 60 marks, 35%) and Paper 3 (structured, 2 hours, 100 marks, 65%). Extended candidates sit Paper 2 (short answer, 1½ hours, 70 marks, 35%) and Paper 4 (structured, 2½ hours, 130 marks, 65%). Papers 1 and 2 prohibit calculators; Papers 3 and 4 allow a silent non-programmable scientific calculator with trigonometric functions.

What grades are available for Core and Extended?

Core is graded C, D, E, F and G. Extended is graded A*, A, B, C, D, E, F and G. U means ungraded. Grade C or better is commonly treated as credit-level for further study; there is no single published numeric percentage pass mark.

When is LGCSE Mathematics examined?

The main examination series is October/November. Availability is open to school and private candidates. Check the current ECoL timetable and registration deadlines on examscouncil.org.ls (for example, 2026 financial registration deadlines are published on the examinations-fees page).

How much does private-candidate entry cost?

On the 2026 ECoL fee table, private LGCSE candidates pay from M910 for one subject up to M2730 for eight subjects. School candidates are registered through their centres. Always confirm the live fee schedule on examscouncil.org.ls before registering.

Are these official ECoL examination questions?

No. Official LGCSE Mathematics uses written short-answer and structured papers, not multiple-choice. This bank is an original English-language MCQ study adaptation aligned to syllabus 0178 content for practice of number, algebra, geometry, mensuration, trigonometry, statistics and probability.
