Today is February 11, 2026. Registration for the 2026 SASMO competition will close soon (early March), and the exam is scheduled for mid-April. For students who have already registered or are planning to register in the final stage, now is the golden time for preparation. This article will provide you with a detailed pre-exam preparation guide.

I. Quick Overview of Core Competition Information

Before making a preparation plan, it is crucial to understand the basic framework of the competition. SASMO is open to students from Primary 1 to Junior College 2 (G1-G12), with separate papers for each grade level to ensure difficulty matches cognitive levels.

2026 SASMO Competition Key Information

Unique Scoring Mechanism: SASMO's scoring rules are quite distinctive. The paper is divided into two sections:

Section A: 15 multiple-choice questions, 2 points each. +2 for a correct answer, -1 for a wrong answer, 0 for no answer.

Section B: 10 short-answer questions, 4 points each. +4 for a correct answer, 0 for a wrong or no answer.

This mechanism requires candidates to be cautious when guessing on multiple-choice questions, but bold in attempting the short-answer questions.

II. Efficient Preparation Strategies

A scientific preparation plan should be progressive. The following three-phase strategy can serve as a reference.

Phase 1: Foundation Consolidation (Now – 1 month before the exam)

Systematically Review Knowledge System: Refer to the official syllabus and systematically review the core knowledge points for your grade, such as basic concepts and formulas in arithmetic, algebra, geometry, number theory, and combinatorics.

Build an Error Log: During practice, categorize mistakes by type (e.g., "calculation error," "conceptual confusion," "wrong approach") and review them regularly.

Phase 2: Skill Enhancement (1 month before the exam)

Focused Breakthrough on High-Frequency Topics: Based on past papers, SASMO has clear trends in question setting. Targeted training is essential.

Application Practice Problems (~40%): Modeling real-life scenarios, such as optimizing traffic routes, calculating discounts, etc.

Graphic Cognition Problems (~20%): Focus on mastering symmetry, 60° rotation, geometric transformations.

Logical Reasoning & Innovative Thinking Problems (increasing proportion): e.g., number table patterns, strategy games, code-breaking.

Core Skill Training:

Number Theory Shortcuts: Master quick judgment of divisibility (e.g., rules for 3, 9, 11) and application of remainder periodicity.

Geometric Intuition: Simplify complex geometric relationships through operations like translation and rotation.

Phase 3: Final Sprint & Mock Exams (2 weeks before the exam)

Timed Mock Exams with Past Papers: Find a quiet environment, strictly simulate the 90-minute exam, and complete full sets of past papers from the last 3-5 years.

Optimize Time Allocation Strategy: Use mock exams to develop a suitable time allocation plan. The following plan can be used as a reference:

Section A (Multiple Choice): Aim to complete within 40 minutes, avoid spending too much time on difficult questions.

Section B (Short Answer): Allocate at least 45 minutes. Ensure you write clear solution steps. Even if the final answer is wrong, a correct approach might earn partial points.

III. Exam Equipment and Material Preparation

Adequate pre-exam preparation guarantees stable performance. SASMO supports both online and offline exam formats, with different preparation requirements.

1. Universal Essential Items

Documents: Admission Ticket (printed in advance) and a valid ID (ID card / Passport / Student ID).

Stationery: At least 2 pencils (2B), black or blue pens, eraser, ruler. Calculators are strictly prohibited.

2. Special Requirements for Online Exams
If you choose the online exam, pay extra attention to the following equipment and environment preparation:

3. Precautions for Offline Exams

Visit the Venue in Advance: Arrive at the exam hall 20-30 minutes early to familiarize yourself with the environment and ease nervousness.

Follow the Rules: Obey the invigilator's instructions. All scratch paper is usually provided uniformly by the exam hall.

IV. Exam Room Techniques and Mindset Adjustment

Answering Order: Adopt an "easy first, difficult later" strategy. Quickly browse the entire paper, complete the questions you are confident about first to secure foundation points, then return to think about difficult questions.

Multiple-Choice Strategy: Due to the point deduction for wrong answers, do not guess blindly on uncertain multiple-choice questions. First, use elimination to narrow down the options. If you still cannot determine the answer, temporarily leaving it blank might be the wiser choice.

Short-Answer Strategy: Process is more important than result. Clearly and logically write down your solution steps, as step-by-step marking is used. Even if the final answer is incorrect,key deduction steps can earn points.

Mindset Adjustment: Use the 15-point starting point mechanism to reduce psychological pressure. Stay calm when encountering difficult questions. Trust your preparation and decisively skip them to avoid affecting subsequent answers.

Today is February 11, 2026. For Chinese students planning to participate in this year's SASMO competition, now is the prime time to learn about this largest math event in Asia. The SASMO competition, with its unique Singapore mathematics education philosophy and relatively high award rate, serves as an ideal starting point for Chinese children to begin their journey in international math competitions.

Organized by the Singapore International Mathematics Contests Centre (SIMCC), SASMO has grown since its inception in 2006 from just 155 local participants to a major event spanning 19 countries with over 20,000 students. Its mature competition system and educational philosophy provide an international stage for Chinese children to showcase their mathematical abilities.

01 Authority and International Recognition

As one of the most influential math competitions in Asia, SASMO's authority stems from the outstanding reputation of Singapore mathematics education. In the latest Trends in International Mathematics and Science Study (TIMSS) reports, Singaporean students have ranked first in mathematical ability for five consecutive cycles, directly reflecting the effectiveness of the Singapore mathematics education system.

The competition is designed for students of all ages from grades 1 to 12, with separate papers for each grade level, ensuring fairness and adaptability. The bilingual (Chinese and English) test papers cater to the language habits of Chinese students while providing an environment for training in international mathematical thinking.

The design of SASMO questions incorporates the essence of Singapore mathematics: the CPA approach, which parses practical problems through the steps of Concrete, Pictorial, and Abstract, cultivating students' modeling thinking. This teaching method has been adopted by over 60 countries and regions globally, including international schools in Shanghai.

The table below summarizes the core information of the SASMO competition:

02 Analysis of SASMO's Core Value

SASMO's value is reflected in multiple dimensions, from its award rate to its advancement mechanism, all demonstrating its unique competitive advantages.

The high award rate is one of the notable features of SASMO. The top 40% of participants can receive Bronze Awards or higher, which is more friendly compared to other international math competitions. This high award rate not only encourages more students to participate but also avoids the frustration that excessive competition might bring.

In terms of competition difficulty, SASMO strikes a good balance between AMC8 and the Kangaroo Math Competition. It is more challenging than Kangaroo Math but not as steep in difficulty as AMC8. This gradient design makes it an ideal transitional competition, especially for Chinese students new to international math contests.

SASMO also establishes a clear advancement pathway. Award winners (Bronze and above) can participate in the SIMOC (Singapore International Math Olympiad Challenge), and Silver award winners and above can advance to the STEAM AHEAD – IJMO competition, building a ladder for participation in higher-level international math events.

In the long run, SASMO awards provide substantial help in further education. For applications to top domestic schools like Shanghai's "San Gong" schools, as well as prestigious overseas universities, the SASMO award certificate serves as a strong proof of mathematical ability, significantly enhancing a student's application competitiveness.

03 Unique Benefits of Participation for Chinese Children

Chinese children participating in the SASMO competition can achieve improvements in multiple aspects, benefits that extend far beyond the competition itself.

Aligning with International Mathematics Education is one of the important gains. The SASMO content integrates the essence of Singapore's CPA teaching method and elements from international math olympiads, helping Chinese children break free from the traditional rote practice model and cultivate stronger modeling thinking and practical problem-solving skills.

For Chinese students whose English skills are still developing, the bilingual test papers lower the language barrier, allowing students to focus more on the mathematics itself. At the same time, by encountering math problems in English, students' specialized vocabulary and comprehension skills in the subject are enhanced.

The SASMO competition is also particularly suitable for compensating for the shortcomings of domestic mathematics education. Domestic math education often emphasizes computational proficiency, while SASMO emphasizes logical reasoning, creative thinking, and critical thinking, thus forming a complementary pair. Many families of high-achieving domestic students choose SASMO to supplement their children's math learning.

From an educational psychology perspective, SASMO's difficulty setting provides students with an appropriate sense of challenge and achievement. Research suggests that this positive competition experience helps cultivate students' long-term interest in mathematics and prevents the phenomenon of "math anxiety."

04 Analysis of Competition Content and Question Types

The design of SASMO questions is scientifically reasonable, comprehensively assessing students' mathematical abilities. The competition lasts 90 minutes and includes 25 questions divided into two sections.

Section A includes 15 multiple-choice questions, each worth 2 points. Points are awarded for correct answers, 0 for no answer, and 1 point is deducted for wrong answers. This mechanism tests students' carefulness and judgment. Section B includes 10 short-answer questions, each worth 4 points. Points are awarded for correct answers, and no points are deducted for no answer or wrong answers. This section requires students to show a complete solution process.

SASMO covers seven major question types: Operation and Solution Problems, Graphic Cognition Problems, Application Practice Problems, Abstract Generalization Problems, Logical Reasoning Problems, Spatial Imagination Problems, and Innovative Thinking Problems. The distribution of these question types is as follows:

Another characteristic of SASMO is its close connection with school knowledge. For students in G1-G2, about 40% of the questions are based on in-class knowledge; for G3-G4, this proportion is about 30%. This means that preparing for SASMO does not detract from school learning but rather reinforces the mastery of in-class knowledge.

Although based on foundational knowledge, the competition questions emphasize the flexible application of knowledge and depth of thinking. For example, a typical integrated question might combine the concept of fractions with area calculation, testing students' ability to solve problems across different knowledge points. This design aligns perfectly with the development direction of modern mathematics education.

05 Preparation Strategies and Path Planning

For Chinese children with different age groups and mathematical foundations, SASMO preparation strategies need to be tailored to the individual. A reasonable preparation cycle is typically 3-6 months, divided into three phases.

The Foundation Phase should focus on consolidating in-class mathematics knowledge, especially core concepts and computational skills for each grade level. For lower grade students, mastering the four arithmetic operations, fractions, decimals, and percentages is key; higher grade students need to strengthen their knowledge of algebra, geometry, and basic number theory.

The Intensive Training Phase should focus on specific SASMO question types and problem-solving techniques. During this phase, students should extensively practice past years' papers, becoming familiar with the presentation and solution approaches for the 7 major question types. In particular, Application Practice and Logical Reasoning problems require repeated practice to master the problem-solving patterns.

The Final Sprint & Mock Exam Phase involves full simulation to train time allocation and test-taking strategies. Due to the point deduction mechanism in Section A, students need to learn to make reasonable trade-offs and avoid blind guessing.

The following table summarizes the preparation focus for students at different grade levels:

In terms of selecting preparation resources, past years' papers are the most important learning material. By analyzing SASMO papers from 2018-2025, students can clearly grasp the question-setting patterns and trends in difficulty. At the same time, focus on organizing and analyzing mistakes, establishing a personal list of weak areas for targeted reinforcement.

For Chinese children, the SASMO competition has transcended the meaning of a mere contest. When a third-grade student uses modeling thinking to deconstruct a complex cycle problem, when a sixth-grade student flexibly applies logical reasoning to crack a number puzzle, mathematics transforms from a dry calculation into a tool for exploring the world.

Mastering the basics, diligently practicing past papers, and targeted breakthroughs – these three keys will help Chinese children shine in this top-tier Asian math competition. Whether they choose to pursue further education domestically or study abroad in the future, the mathematical thinking and problem-solving skills cultivated by SASMO will become assets they can rely on for a lifetime.
