Overview of the
Junior Cert Honours Maths Paper
Mr. Roche
Paper 1
Question 1: Arithmetic;
Percentages, Profit and Loss, possible currency calculations and Income Tax/Tax Credits
calculations. Speed, distance, time. Approximation/rounding off.
Question 2:
Sets and a test as to how much you know about your calculator. BEMDAS. More arithmetic.
Question 3:
Algebra. A bit of everything. (i) Solve an equation, (ii) write one thing in terms of another (iii)
solve a quadratic equation (with formula). Indices. Word problem involving simultaneous
equations.
Question 4:
More Algebra The emphasis here may be on factors and a word problem involving a quadratic
equation.
Question 5:
More algebra, and the graph of a quadratic function and some questions based on the graph.
Question 6:
Inequalities and simultaneous equations. They also ask some questions on a given graph of a
quadratic function. Other algebra as above.

Paper 2
Question 1: Area and Volume.
They will definitely ask a question about the perimeter. The rest of the question will be based
on Cones, cylinders and spheres.
Question 2: Coordinate Geometry of the Line.
You will be tested on you knowledge of and ability to use the (four) Coordinate Geometry
Formula.
Question 3: Geometry.
This will be the main geometry Question
They will ask you to prove a theorem more than likely using congruent triangles. You may
also be asked to construct a triangle or a parallelogram.
Question 4: Geometry.
It is likely that in this question the will ask you to prove one of the last 5 theorems.
Question 5: Trigonometry
You can expect a lot of the question to be based on a right angled triangle. Use of the Sine
rule will also be examined.
Question 6: Statistics.
This should be the easiest question on the paper ie Bar Charts, Pie Charts, Histograms,
Mean, Median of a frequency table.
