Singapore Math Olympiad (SMO vs SASMO vs SIMOC): Eligibility, Syllabus, Registration & Preparation Guide

If you search for the Singapore Math Olympiad, you will find three names again and again: SMO, SASMO and SIMOC. Many parents and students think these are the same exam. They are not. Each one has a different organiser, a different group of students and a different purpose. Choosing the wrong one can waste a year of preparation.

This guide explains the three contests in simple language. You will learn who can take part, what the exam looks like, what topics to study, how to register and how to prepare step by step. Details were checked against official and school sources in October 2026. Fees and dates change every year, so always confirm them on the official website before you pay.

    What Is the Singapore Math Olympiad?

    There is no single exam called “the Singapore Math Olympiad”. The phrase is used for several contests linked to Singapore’s strong maths culture. People use it for SMO, for SASMO, and sometimes for SIMOC.

    Singapore is well known for its maths teaching method, which uses pictures, bar models and step-by-step thinking. These contests build on that approach. They ask students to think, not just to remember formulas. A student who enjoys puzzles and problem solving usually enjoys these papers.

    A small note for readers in India: in India, “SMO” can also mean the Senior Mathematical Olympiad run by Indian bodies. That is a different exam. In this article, SMO always means the Singapore Mathematical Olympiad.

    Singapore Mathematical Olympiad (SMO)

    Who organises it

    The Singapore Mathematical Society has run this contest since 1956. It was renamed the Singapore Mathematical Olympiad in 1995. It has three sections: Junior, Senior and Open.

    Eligibility

    SMO is meant for students who study in Singapore. The society publishes fresh rules every year, so check the current rules before you plan. The 2025 rules gave this picture:

    • Junior Section: Secondary 1 and 2 students, born on or after 2 January 2011.
    • Senior Section: Secondary 3 and 4 students, born on or after 2 January 2009.
    • Open Section: Full-time students from Secondary 1 to Secondary 4 and Junior College.
    • In all sections, the student must never have attended a tertiary institution full-time.

    Exam format

    SMO has two rounds. Round 1 for the Junior Section is a written paper of two and a half hours with multiple-choice and short-answer questions. Strong performers move to Round 2. The Open Section Round 2 is also used to help select the Singapore National Training Team for the International Mathematical Olympiad in the following year.

    Syllabus

    SMO papers go beyond the school textbook. The common areas are:

    • Algebra and equations
    • Number theory (factors, remainders, primes)
    • Geometry (angles, triangles, circles)
    • Combinatorics and counting
    • Trigonometry (more common in Senior and Open sections)

    Registration

    Students do not register alone. The school’s Head of Department for Mathematics sends the names and fees to the contest committee before the closing date. So, if you study in Singapore, speak to your maths teacher early in the year.

    Awards

    Prizes go to the top 30 scorers in each section, based on the total of Round 1 and Round 2 scores. Schools also receive Gold, Silver, Bronze or Commendation awards, and the top school gets a challenge trophy or shield.

    Singapore and Asian Schools Math Olympiad (SASMO)

    Who organises it

    SASMO is organised by the Singapore International Mastery Contests Centre (SIMCC). It began in 2006. SIMCC describes it as one of Asia’s largest maths olympiads, with students from over 50 countries taking part.

    Eligibility

    SASMO is open to students from Kindergarten 2 up to Grade 12, and each grade writes its own paper. Eligibility depends on the grade you are studying in at the time of the exam. Registration goes through SIMCC’s country partners, so the rules and fees can differ from one country to another.

    Exam format

    The paper is 90 minutes long and has 25 questions in two sections:

    • Section A: 15 multiple-choice questions. A correct answer earns 2 points, and a wrong answer loses 1 point.
    • Section B: 10 questions where the answer is a whole number. These carry more marks.

    Calculators are not allowed. Students have to do all the work on scrap paper. Some schools also ask students to finish an online practice module before the contest, as one school in Singapore did in 2026.

    Dates and fees

    SASMO is held once a year, usually in April. In 2026, the exam in India was reported for 5 April, with a registration deadline of 25 March and a fee of ₹1,800 per student. In a Singapore school, the fee for the same contest was $30. These two numbers show why you must check your own country partner’s page.

    Syllabus

    SASMO papers are written for the student’s grade. They use school-level content, but the questions need clever thinking. Expect these topics:

    • Primary levels: whole numbers, fractions, patterns, simple geometry, time, money, logic puzzles.
    • Middle levels: ratio, percentage, speed, algebra basics, area and perimeter, number puzzles.
    • Higher levels: algebra, geometry, number theory, counting, probability and reasoning.

    SIMCC says the contest is designed so that about the top 40% of participants earn medals and certificates. That makes it friendlier than very elite contests, and a good first olympiad for beginners.

    Awards

    Medals and certificates go to the top 40% of participants. Gold, Silver and Bronze medallists are usually invited to the next stage, SIMOC, and the best may also be invited to the International Junior Mathematics Olympiad.

    Singapore International Math Olympiad Challenge (SIMOC)

    SIMOC is the international final that follows SASMO. In 2026 it was held in Singapore from 17 to 21 July. A school report from Nigeria said it brought together 2,285 students from 1,113 schools across 40 countries.

    Eligibility

    Entry is mainly by invitation. Students who win medals at SASMO, and in some cases other partner contests, receive the invitation. You cannot normally apply directly. Parents also need to plan for travel, stay and visa costs, because the finals take place in Singapore.

    What happens at SIMOC

    The event has three parts:

    1. Math Olympiad: an individual written paper.
    2. Maths Warrior: a team contest.
    3. Maths Master Mind: another team contest that tests quick thinking and teamwork.

    This makes SIMOC more than an exam. Students meet peers from many countries, which is a big reason families value it.

    SMO vs SASMO vs SIMOC: Which One Is Right for You?

    Use these simple rules to decide.

    • You study in a Singapore school and enjoy hard problems: Ask your school about SMO. It is the national contest and a stepping stone to the Singapore team.
    • You live outside Singapore, or you are in a primary grade: SASMO is the right place to start. It accepts students from K2 onward and works through local partners.
    • You won a medal at SASMO and got an invitation: SIMOC is your next step. Talk to your country partner about the travel plan.
    • You are a beginner: Start with SASMO. Do not jump straight to SMO unless your school enters you.

    A student can often do more than one. For example, a Singapore student may take both SASMO and SMO in the same year, because the two exams fall in different months.

    Step-by-Step Registration Guide

    The exact process depends on the contest and your country, but these steps work for most families.

    1. Find the official page. For SASMO, start from the SIMCC website and look for your country partner. For SMO, check the Singapore Mathematical Society’s website.
    2. Check the grade rules. Make sure your child’s grade fits the category.
    3. Note the deadline. Registration often closes a few weeks before the exam. In 2026, the SASMO deadline in India was 25 March for an exam on 5 April.
    4. Register through the right route. SMO goes through the school. SASMO can go through the school or a country partner, and in some countries individual registration is also possible.
    5. Pay only on official portals. Be careful with fake websites and agents who ask for extra money.
    6. Save the confirmation. Keep the registration number, because you will need it for the admit card and results.
    7. Download the admit card and read the instructions. Check the time, venue and rules about calculators and stationery.

    How to Prepare for the Singapore Math Olympiad

    Good preparation is steady and simple. Fancy tricks matter less than daily practice.

    Step 1: Fix the school basics first

    Olympiad questions use school concepts in new ways. If fractions, ratio or algebra feel weak, fix them first. A student who is shaky on basics will struggle to solve even easy olympiad problems.

    Step 2: Learn the Singapore-style methods

    Tools like the bar model, number lines and working backwards help in many word problems. Learn to draw the problem before you calculate.

    Step 3: Practise with past papers

    Past papers are the best study material. They show the real difficulty and the style of questions. Time yourself on a full 90-minute paper once the topics are covered. Check the official site of the contest for past papers and guidebooks.

    Step 4: Build mental maths and speed

    Since calculators are not allowed, accuracy with numbers matters. Practise squares, multiplication tables and quick estimation for ten minutes a day.

    Step 5: Keep an error notebook

    Write each mistake, the reason for it, and the correct method. Review the notebook every week. Most students find that the same three or four mistakes appear again and again.

    Step 6: Learn the marking rules

    Some papers deduct marks for wrong answers. Learn when to guess and when to skip. A careful skip is better than a random guess when penalties apply.

    Step 7: Practise explaining solutions

    Ask your child to explain a solution aloud. If they can teach it, they will understand it.

    Step 8: Rest well before the exam

    A light revision and good sleep on the last two days work better than a late-night cram.

    Sample 12-Week Study Plan

    This plan suits a student who has about three months before SASMO. Adjust it for the grade and the time you have.

    Weeks

    Focus

    Daily time

    1-3

    Revise school topics, fix weak areas

    30-45 minutes

    4-6

    Topic-wise olympiad questions: number, patterns, geometry

    45 minutes

    7-9

    Mixed practice, word problems, mental maths

    45-60 minutes

    10-11

    Full timed past papers, check errors

    60 minutes

    12

    Light revision, rest, exam day plan

    20-30 minutes

    For younger children in Class 1-3, shorter sessions of 20 to 30 minutes with games and puzzles work better.

    Common Mistakes to Avoid

    • Starting only two weeks before the exam.
    • Memorising answers instead of learning methods.
    • Ignoring the negative marking rules.
    • Practising only easy questions.
    • Skipping the error notebook.
    • Putting too much pressure on the child. Olympiads should build interest in maths, not fear.

    Tips for Parents and Teachers

    • Praise effort and good thinking, not only medals.
    • Let the child struggle with a problem for a few minutes before you step in.
    • Use real-life examples, such as shopping bills, travel time and simple puzzles.
    • Keep a balance with play, sleep and school work.
    • If your child loses interest, change the style of practice before you quit.

    Conclusion

    The Singapore Math Olympiad family has a place for almost every young learner. SMO suits students in Singapore who want a national challenge. SASMO opens the door for children from K2 to Grade 12 around the world. SIMOC rewards the best SASMO performers with an international final in Singapore.

    Pick the contest that matches your location and grade, confirm the dates on the official website, and prepare with steady daily practice. With basics in place, good past-paper practice and a calm mindset, students can enjoy the process and grow in confidence, whatever the final medal says.
