What Mathematics Will Students Practise?
The challenge connects several mathematical topics, encouraging students to recognise relationships and select efficient methods rather than relying only on familiar formulas.
1. Gradients & Straight Lines
Solve coordinate geometry problems involving gradients, intercepts, collinearity, intersections and equations of straight lines.
2. Parallel Lines & Angles
Apply angle relationships, transversal rules, angle bisectors and the properties of regular polygons.
3. Perpendicular Lines & Geometry
Explore perpendicular gradients, perpendicular bisectors, distances, triangles, squares, circles and coordinate transformations.
4. Linear Functions & Equations
Practise function notation, repeated functions, algebraic relationships, absolute-value equations and integer-coordinate solutions.
5. Binomial Theorem
Extend algebraic understanding through expansions, coefficients, constant terms, middle terms and numerical patterns.
6. Mathematical Reasoning
Connect algebra and geometry, identify hidden relationships and select appropriate methods for unfamiliar problems.
How Is the Olympiad Challenge Structured?
Section I
General Problems
Questions 1–30
30 Marks
Thirty mixed mathematics questions test knowledge, reasoning and efficient problem-solving methods.
Scoring:

Section II
Themed Advanced Problems
Questions 31–50
40 Marks
Twenty advanced questions are organised into four themed problem-solving sections.
Scoring:
- Correct answer: +2 marks
- Incorrect answer: −0.5 marks
- Unanswered question: 0 marks
The four advanced themes are:
- Parallel Lines and Angles
- Perpendicular Lines and Coordinate Geometry
- Linear Functions and Equations
- The Binomial Theorem
Total: 50 Questions | 70 Marks | 90 Minutes
Calculators are not permitted. Students may use scrap paper for working.
Why Is This Different from an Ordinary Maths Worksheet?
Traditional worksheets often focus on repeating a single method. This Olympiad challenge encourages students to recognise mathematical connections across different topics.
A coordinate geometry problem may require geometric area reasoning. A binomial expansion question may become easier by identifying a coefficient pattern. A linear-function problem may involve an unexpected algebraic relationship.
Students practise how to:
- Recognise hidden mathematical structures.
- Select efficient problem-solving methods.
- Connect geometry and algebra.
- Solve unfamiliar questions under time pressure.
- Evaluate multiple-choice answers strategically.
- Develop confidence with advanced mathematical reasoning.
Learn from Every Question with Full Worked Solutions
A correct answer tells students whether they succeeded. A worked solution helps them understand why.
The accompanying answer key provides an answer grid and question-by-question worked solutions.
Students can review mistakes, identify alternative approaches and strengthen their understanding of the mathematical ideas behind each question.
Parents and teachers can also use the separate answer key to support independent practice, guided learning and targeted revision.
Attempt
Work through the exam independently before consulting the answers.
Understand
Study the worked solutions to understand the reasoning behind each answer.
Improve
Revisit difficult questions and practise the underlying mathematical concepts.
Who Is This Maths Olympiad Paper For?
Year 9 Students
Students seeking mathematics challenges beyond routine school exercises.
Grade 8–9 Students
Learners with strong mathematical foundations who are ready for advanced practice.
Maths Olympiad Participants
Students developing competition-style mathematical reasoning and problem-solving skills.
IB MYP Students
Learners seeking enrichment in geometry, algebra and mathematical reasoning.

Parents, Teachers & Tutors
Educators looking for a structured advanced mathematics assessment resource.
Important: The binomial theorem and some coordinate geometry problems extend beyond typical Year 9 classroom expectations. This resource is intended for mathematically confident students rather than as a standard curriculum revision test.
How to Use This Maths Olympiad Challenge
Step 1 – Attempt the Exam Independently
Set a 90-minute timer and complete the examination without a calculator.
Step 2 – Apply the Scoring Rules
Record your answers on the answer sheet and calculate your score out of 70, accounting for negative marking.
Step 3 – Review the Worked Solutions
Compare your answers with the answer key and study the methods used to solve each problem.
Step 4 – Reattempt Difficult Questions
Try solving missed questions again without looking at the solutions.
Step 5 – Track Your Progress
Identify weaker topics and revisit them before attempting another advanced mathematics challenge.
