Welcome to the Brainiacs Mathematics Olympiad!

In today’s exciting and fast-moving world, mathematics is the secret superpower behind many amazing achievements. Mathematics is often called the “universal language,” and for a good reason. Whether it’s building skyscrapers, designing cutting-edge technology, or exploring the mysteries of space, math is at the heart of it all! It connects people across the globe, helps us understand our universe, and offers solutions to the toughest problems.

The Brainiacs Mathematics Olympiad is here to inspire students and show them the thrill of problem-solving and critical thinking. We want students to dive into the world of math and discover just how powerful and fun it can be! This Olympiad isn’t just about solving equations, it’s about learning to think critically, tackle challenges with confidence, and develop skills that will help them in every area of life.

The future belongs to those who think boldly and creatively, and math is the tool that will guide them there. Let’s unlock the brainiac in every student!

Join us!

Experience the thrill of competition and the joy of achievement.

Brainiacs Mathematics Olympiad Mechanics

The Brainiacs Mathematics Olympiad is a globally renowned competition aimed at encouraging creativity, innovation, and academic excellence in students from Grade 3 to Grade 12. The Olympiad is structured into two main stages: the Preliminary Round and the Global Round

PRELIMINARY ROUND REGISTRATION

Students can register for the Olympiad through the official Brainiacs Olympiad website or via authorized representatives in their respective countries.

Dates

The online qualifying exams for the Preliminary Round are scheduled for:

Online I: November 15, 2025 (Registration deadline: November 14, 2025)
Online I Results: November 20, 2025
Online II: December 20, 2025 (Registration deadline: December 19, 2025)
Online II Results: December 25, 2025

The two online rounds are the same, but feature different questions.

Those who did not qualify for the global round in the first online round, along with those who were absent from the first round, can participate in the second round.

Format

The exam consists of 20 questions divided into three levels of difficulty:

Easy: 5 questions
Normal: 10 questions
Difficult: 5 questions

The exam consists of 20 multiple-choice questions to be completed within 75 minutes. Questions are tailored to the participant’s educational level and divided into the following categories:

Category 1: Grades 3 and 4
Category 2: Grades 5 and 6
Category 3: Grades 7 and 8
Category 4: Grades 9 and 10
Category 5: Grades 11 and 12

Scoring

Easy Questions: +4 points for each correct answer
Normal Questions: +5 points for each correct answer
Difficult Questions: +6 points for each correct answer
Incorrect Answer: No negative marking for any question
Unanswered Question: No points deducted

Qualification

Participants scoring at least 40% in the Preliminary Round qualify for the Global Round. Every participant receives a Certificate of Participation.

Recognition

In the Preliminary Round, medals are awarded based on the points earned by the participants:

40 to 49 : Honorable Mention Certificate
50 to 74 : Bronze Medal
75 to 89 : Silver Medal
90 to 100 : Gold Medal

GLOBAL ROUND

The Global Round is the final stage of the competition, where participants showcase their knowledge and ability.

Registration

Students can register for the Olympiad through the official Brainiacs Olympiad website or via authorized representatives in their respective countries.

Dates and Venue

Global Round of the 2nd Brainiacs Olympiad will take place in Xiamen University Malaysia from March 24 to 30, 2026.

Standard Registration Deadline: February 1, 2026
Late Registration Deadline: March 1, 2026

Exam Days

Global Round exam format is different from Preliminary Round. It has both Theoretical and Practical parts separated in two consecutive examination days.

Day 1. Theoretical Part

This is the traditional portion of a math exam – it tests understanding, reasoning, and proof-based skills.

Examples:

Solving algebraic equations, inequalities, and geometry problems
Writing proofs (e.g., “Prove that triangle ABC is isosceles if…”)
Explaining why a formula works
Short-answer or multiple-choice conceptual questions

Purpose:

To test mathematical knowledge, reasoning, problem-solving ability, and abstract thinking.

Day 1 Exam Format

The exam consists of 20 questions divided into three levels of difficulty:

Easy: 5 multiple-choice questions
Normal: 5 multiple-choice questions
Difficult: 5 multiple-choice questions
Open-ended(difficult): 5 questions

The exam consists of 15 multiple-choice and 5 open-ended questions to be completed within 120 minutes.

Day 1 Exam Scoring

Easy Questions: +3 points for each correct answer
Normal Questions: +4 points for each correct answer
Difficult Questions: +5 points for each correct answer
Open-ended: +8 points for full correct solution and answer
Incorrect Answer: No negative marking for any question
Unanswered Question: No points deducted

Day 2. Practical Part

The practical part checks how students can apply mathematical knowledge in real-world or experimental situations (applications, data-based or computational tasks).

Examples:

Using math to analyze real-life data (like temperature, prices, or measurements)
Modeling a real-world situation (e.g., “Estimate how many tiles are needed to cover a floor of size X”)
Measuring and calculating in geometry using tools (ruler, compass, protractor)

Purpose:

To test application, data analysis, modeling, and use of tools or technology in mathematical contexts.

Day 2 Exam Format

The exam consists of 10 questions divided into three levels of difficulty:

Easy: 3 multiple-choice problems
Normal: 3 multiple-choice problems
Difficult: 4 open-ended problems

The exam consists of 6 multiple-choice and 4 open-ended problems to be completed within 120 minutes.

Day 2 Exam Scoring

Easy Questions: +7 points for each correct answer
Normal Questions: +9 points for each correct answer
Difficult Questions: +13 points for each correct answer
Incorrect Answer: No negative marking for any question
Unanswered Question: No points deducted

Global Round Recognition

In the Global Round, medals are awarded based on the percentage distribution according to the number of participants.

The top 10% (0-10%) of participants receive gold medals.
The next 20% (11-30%) of participants receive silver medals.
The next 30% (31-60%) of participants receive bronze medals.
The next 15% (61-75%) receive honorable mentions.
