What levels can students take Junior Cycle Mathematics at?

Junior Cycle Mathematics can be taken at Higher Level or Ordinary Level. Both levels sit a single two-hour written examination covering all five strands, with the Higher Level paper extending and deepening the Ordinary Level material.

How long is the Junior Cycle Mathematics examination?

The final written examination is two hours long at both Higher and Ordinary Level. The Higher Level paper is marked out of 270 marks.

Can students use a calculator?

Yes. Candidates may use a calculator and the official State Examinations Commission Formulae and Tables booklet in the written examination. Working should still be shown clearly to earn method marks.

What are the five strands of Junior Cycle Mathematics?

The five strands are Statistics & Probability, Geometry & Trigonometry, Number, Algebra and Functions. A unifying strand develops problem solving, reasoning and communication across all of them.

Is there a pass mark for Junior Cycle Mathematics?

No. Results are reported using descriptors such as Higher Merit, Merit, Achieved, Partially Achieved and Not Graded, based on the percentage of marks gained, rather than a simple pass or fail.

Are these official SEC examination questions?

No. These are original OpenExamPrep practice questions written to match the Junior Cycle strands and level. Official past papers and marking schemes are available free from the State Examinations Commission at examinations.ie.

OpenExamPrep

Junior Cycle Mathematics is Ireland's lower-secondary maths qualification, set by the State Examinations Commission for third-year students around age 15. It is built on five strands - Number, Algebra, Geometry & Trigonometry, Statistics & Probability and Functions - plus a unifying problem-solving strand. Students sit a single two-hour written paper at Higher or Ordinary Level, with a calculator and the official Formulae and Tables booklet permitted; Higher Level is marked out of 270. Results are reported as descriptors (Higher Merit, Merit, Achieved, Partially Achieved, Not Graded) rather than a pass mark. This 100-question bank provides original single-best-answer practice across all five strands.

1What is the value of -7 + 12 - 5?

A.0

B.-10

C.10

D.24

Explanation: Work left to right: -7 + 12 = 5, then 5 - 5 = 0. Combining the negatives and positives gives a result of 0.

2Evaluate 3 + 4 x 2 using the correct order of operations.

A.14

B.11

C.10

D.24

Explanation: Multiplication is done before addition: 4 x 2 = 8, then 3 + 8 = 11. Order of operations (BIMDAS) requires multiplication first.

3What is 2/3 + 1/4?

A.3/7

B.11/12

C.3/12

D.5/7

Explanation: Use a common denominator of 12: 2/3 = 8/12 and 1/4 = 3/12. Then 8/12 + 3/12 = 11/12.

4What is 0.6 written as a fraction in its simplest form?

A.6/10

B.3/5

C.2/3

D.1/6

Explanation: 0.6 = 6/10, and dividing top and bottom by 2 gives 3/5. So 0.6 = 3/5 in simplest form.

5Find 15% of 240.

A.36

B.24

C.360

D.16

Explanation: 15% of 240 = 0.15 x 240 = 36. You can also find 10% (24) plus 5% (12) to get 36.

6A jacket costs 80 euro. In a sale it is reduced by 25%. What is the sale price?

A.55 euro

B.60 euro

C.75 euro

D.20 euro

Explanation: 25% of 80 is 20, so the reduction is 20 euro. The sale price is 80 - 20 = 60 euro.

7Share 350 euro between two people in the ratio 3 : 4. How much does the person on the larger share receive?

A.150 euro

B.200 euro

C.175 euro

D.210 euro

Explanation: The ratio has 3 + 4 = 7 parts, so one part is 350 / 7 = 50 euro. The larger share is 4 parts = 4 x 50 = 200 euro.

8If 5 identical pens cost 6.25 euro, what is the cost of 8 such pens?

A.10 euro

B.9.75 euro

C.12.50 euro

D.8 euro

Explanation: One pen costs 6.25 / 5 = 1.25 euro. Eight pens cost 8 x 1.25 = 10 euro.

9Write 45 000 in scientific notation.

A.4.5 x 10^4

B.45 x 10^3

C.4.5 x 10^3

D.4.5 x 10^5

Explanation: Scientific notation needs a number between 1 and 10 multiplied by a power of 10. 45 000 = 4.5 x 10 000 = 4.5 x 10^4.

10What is the value of 2^5?

A.10

B.25

C.32

D.16

Explanation: 2^5 means 2 x 2 x 2 x 2 x 2 = 32. The exponent tells you how many times to multiply 2 by itself.
