Helping your child prepare for a Math Olympiad takes more than long hours of practice. The months leading up to the June competition season are decisive, and the right approach makes the difference between steady progress and avoidable setbacks. Even highly motivated students can unknowingly fall into habits that limit their performance.
This guide outlines the most common Math Olympiad preparation mistakes and how to build stronger problem-solving skills before the June window. Whether your child is sitting for their first competition or returning for another medal attempt, sound math competition preparation begins with avoiding these pitfalls early..
Key Takeaways
- The months before June are the most decisive window for building Math Olympiad readiness, before the competition season peaks in July and August.
- Success in Math Olympiads requires logical reasoning rather than the rote memorisation of templates or formulas.
- A well-rounded preparation strategy must cover a comprehensive range of topics, such as Number Theory and Combinatorics, to avoid significant point losses.
- Developing mastery and accuracy should always take precedence over speed, as true problem-solving quickness is a byproduct of conceptual confidence.
- Maintaining a balanced schedule that prioritises rest prevents burnout and keeps the mind sharp for Math Olympiad performance.
Major Math Olympiads in the June Window
Several competitions take place around or immediately after the June period. The following events are central to the mid-year Math Olympiad calendar in Singapore:
- NMOS (National Mathematical Olympiad of Singapore): Organised by NUS High School of Mathematics and Science, this competition is open to Primary 5 students only and is held in mid-July.
- SMO (Singapore Mathematical Olympiad): Organised by the Singapore Mathematical Society, this is the flagship competition for secondary school and junior college students. It is split into Junior, Senior, and Open sections. Round 1 typically takes place in late May or early June, with Round 2 following about a month later.
- SIMOC (Singapore International Math Olympiad Challenge): Held in July, this competition attracts students from around the world. It comprises an individual written paper alongside two team-based challenges, Math Warriors and Math Master Mind.
- APMOPS (Asia-Pacific Mathematical Olympiad for Primary Schools): Organised by Hwa Chong Institution, this two-round competition is designed to identify top mathematical talent across the Asia-Pacific region. Round 1 is held in April, with the Invitation Round in late May or early June.
Preparing for the Second Half of the School Year
Olympiad preparation also coincides with a more demanding stretch of the school year. The second half of the academic year in Singapore introduces students to newer and more advanced topics. For primary students, areas like Ratio, Speed, and Volume require a higher level of conceptual understanding. For secondary students, algebra and geometry grow noticeably more complex.
Students who use the pre-June window well tend to stay ahead of the school curve. They master these topics conceptually before they appear in the classroom, which makes the new material easier to absorb and frees up mental space for Olympiad work.
4 Common Maths Competition Preparation Mistakes
In our experience as a tuition centre, we have observed how different students approach Math Olympiad preparation. Four recurring mistakes consistently hold students back in the months leading up to the June season.
Mistake 1: Memorising
Math Olympiads are not about rote memorisation. They are about problem-solving, where students work through questions like puzzles, each with its own logic to uncover.
This leads to the first common mistake. Students try to memorise question types and standard steps to solving them. In a school setting, this can work because school exams are usually formatted in line with the textbook. Olympiad questions, however, are designed to be non-routine. A student who memorises a template will be left stranded the moment the question is rephrased or given an unfamiliar twist.
Your child should focus on the reasoning behind every solution. At Terry Chew Academy, we teach students to derive their own formulas. Instead of memorising a rule, they practise breaking a problem down into its fundamental parts. We encourage students to solve the same problem using two, three, or four different methods. This builds true flexibility and gives them a more holistic understanding of the question types they will encounter.
In summary:
- Avoid memorising templates and fixed steps for solving problems.
- Teach your child to derive formulas from first principles.
- Solve the same problem using multiple methods to build flexibility.
- Focus on understanding the reasoning, not the procedure.
Mistake 2: Topic Imbalance
Students naturally gravitate towards what they are already good at. An algebra lover might focus on solving algebra problems and quietly avoid Geometry. This creates both an affinity and a hidden weakness.
Olympiad papers are designed to be comprehensive, and a student who lacks skills in any one area will lose marks there. Take, for example, a student who spends most of their time mastering Number Theory but neglects Combinatorics. During the NMOS, they might find that several questions involve counting paths or arrangements. Even though the student is strong in prime numbers, they cannot secure a strong placement because they have left a meaningful portion of the paper blank.
Being well-rounded is essential. The core areas every Math Olympiad student should cover include:
- Number Theory: Factors, multiples, divisibility, and remainders.
- Combinatorics: Permutations, combinations, and counting principles.
- Geometry: Angles, area, perimeter, and spatial reasoning.
- Algebra: Equations, inequalities, and sequences.
- Logic: Cryptarithms, the pigeonhole principle, and truth tables.
Students tend to be biased towards topics they are already comfortable with, so it helps to build a study schedule that places extra time on their weakest areas. If your child loves Algebra, they should spend one part of their time on Algebra and two parts on Geometry. A balanced topic checklist is one of the simplest yet most effective tools in math competition preparation.
In summary:
- Identify your child's weakest topic and prioritise it.
- Cover Number Theory, Combinatorics, Geometry, Algebra, and Logic.
- Use a topic checklist to ensure no area is left behind.
- Allocate more practice time to weaknesses than to strengths.
Mistake 3: Prioritising Speed Over Accuracy
A lot of students try to solve problems as quickly as possible, prioritising speed over accuracy. Schools often applaud those who can solve problems in seconds, but this speed is a byproduct of conceptual mastery rather than the goal itself.
Many students prepare by timing themselves or racing among friends to see who can finish first. This is an inefficient way to train. Their stress comes from the pressure of the clock, not the satisfaction of solving the problem, and small lapses become hard to avoid.
We see arithmetic slips constantly. A student writes 2^3 as 6, when it should be 8, because the mind takes the shortcut of 2 × 3 instead of 2 × 2 × 2. Or a student writes (2^3)^3 as 2^6 instead of 2^9, hastily adding the exponents instead of multiplying them.
Speed should never be the primary goal. It develops naturally as students gain knowledge, mastery, and confidence. Time spent reinforcing accuracy is never wasted.
In summary:
- Build accuracy first, then let speed follow naturally.
- Avoid speed drills as a primary training method.
- Reinforce conceptual mastery to reduce arithmetic slips.
- Use timed practice only after fundamentals are secure.
Mistake 4: Not Getting Enough Rest
Success in Math Olympiads depends on creativity, critical thinking, and clear procedural reasoning. Yet we regularly see students completing homework late into the night or training at the expense of rest.
Overworking dulls the very cognitive functions Olympiad questions demand. The Singapore Ministry of Health's Health Promotion Board recommends that children aged 7 to 12 get 9 to 11 hours of sleep each night, with academic performance and concentration clearly linked to adequate rest. A tired brain works more slowly, makes more mistakes, and is far less likely to find the creative leap a non-routine question rewards.
Ensure your child has a consistent sleep schedule and regular breaks. Math Olympiad preparation is a marathon, not a sprint. We recommend focused 90-minute study blocks followed by physical activity. At Terry Chew Academy, we keep homework purposeful and manageable so students arrive at each session refreshed and ready to think.
In summary:
- Keep a consistent sleep schedule throughout the preparation window.
- Use 90-minute study blocks followed by short physical breaks.
- Avoid late-night cramming, which weakens problem-solving.
- Treat rest as part of the training plan, not as its opposite.
How to Prepare Effectively Before June
The right preparation routine turns the months before June into a steady build rather than a stressful sprint. By the time the June programmes arrive, your child should feel invigorated and challenged, not overwhelmed. Effective math competition preparation in this period blends consistent practice, structured exposure, and the right learning environment.
Engage with Fellow Math Olympiad Participants
Mathematics does not have to be a lonely subject. When your child talks to other students who are also preparing for competitions, they learn new perspectives. They can compare different ways of solving the same problem and share their experiences from past papers.
This social interaction makes the learning process more enjoyable. It also sets a healthy benchmark and motivates students to keep pace with their peers.
Understand the Different Topics
Your child must be familiar with the scope of each competition. As mentioned, topics like Number Theory and Combinatorics are often outside the standard school syllabus but are central to the Olympiad. Make sure your child has resources that thoroughly cover these areas.
Tutors at established tuition centres typically have direct experience with Math Olympiad question styles. Working with them gives students a broader, more accurate view of what competitions actually require.
Build a Structured Schedule
A consistent weekly plan is far more effective than long, irregular bursts of practice. Map out topic coverage across the weeks leading up to June, allocate more time to weak areas, and build in rest days. Treat the schedule like a training plan, not a to-do list.
Join June Bootcamps
June bootcamps are intensive training programmes held during the mid-year school holidays. They typically run for 5 days and focus on non-routine problems that students rarely encounter in the classroom.
The June holiday is the only significant break before the peak Math Olympiad season begins in July and August. Without daily school homework, your child can devote their full attention to advanced concepts. Students who maintain momentum through this period tend to keep their problem-solving speed and confidence; those who stop practising often see both drop.
A well-designed bootcamp also serves as a final intensive review, sharpening the heuristics and reasoning patterns that competition papers reward.
Enrol in Maths Tuitions
Regular, consistent guidance is the best way to build long-term skills. A weekly tuition session ensures that your child is challenged on a steady cadence, rather than only in short bursts before competitions.
Math tuition centres typically have smaller class sizes than traditional school settings, allowing tutors to give each student more focused attention. Students are also surrounded by classmates with similar mathematical proficiency, which lifts the standard of the room.
At Terry Chew Academy, we provide a curriculum that supplements classroom learning, preparing students for both school excellence and Math Olympiad success.

Frequently Asked Questions
How early should my child start preparing for a Math Olympiad?
Most students benefit from beginning at least six months before their target competition, with weekly practice that builds heuristics, topic coverage, and exam confidence. Starting earlier is even better, as Math Olympiad thinking is a skill set that compounds over time.
What is the difference between school math and Math Olympiad preparation?
School math focuses on the standard syllabus and repetitive procedures designed to test mastery of taught content. Math Olympiad preparation focuses on non-routine problems that demand reasoning, creative leaps, and flexible application of concepts across topics.
How do I know if my child is ready to attempt a Math Olympiad?
A child is generally ready when they show genuine curiosity about problem-solving, can work through a question patiently without giving up, and can handle unfamiliar question formats without becoming discouraged. A diagnostic session with an experienced coach is the most reliable way to confirm readiness.
Is a June bootcamp suitable for students who have never joined a math competition before?
Yes. A well-structured bootcamp is one of the best ways to get a focused introduction to competition logic, helping beginners build the confidence they need to participate in their first event.
Are the topics covered in a bootcamp applicable to the PSLE or O-Level exams?
While the primary focus is on Math Olympiads, the advanced algebra, geometry, and problem-solving techniques taught significantly improve a student's ability to tackle the more challenging sections of national exams.
