TIMO
Thailand International Mathematical Olympiad
2025-26
ABOUT TIMO
Thailand International Mathematical Olympiad (TIMO) is an annual Mathematical Olympiad competition organised by Olympiad Champion Education Center (OCEC) and the Thailand Mathematics Society. As the majority of Mathematical Olympiad competitions are only focusing on 0.1% of the elite students, TIMO provides an opportunity for ALL students with strong interests in Mathematics to participate in Mathematical Olympiad competition.
What makes TIMO special is that after the competition, TIMO will release the general statistics of students’ performance which shows the strength and weaknesses of the candidates on the following topics such as Logical Thinking, Arithmetic / Algebra, Number Theory, Geometry and Combinatorics. Students can then apply the analytics on their individual learning strategy.
TIMO Heats is conducted at country level to identify Mathematical talent who can then participate in TIMO Finals in Thailand subject to qualifying and registering. TIMO and HKIMO Finals gold award winners (need to win Gold medals in both finals) are then eligible for WIMO (World International Mathematical Olympiad) along with a free Olympiad training workshop.
TIMO integrates both competition and tour. Our coaches, administrators, and staff stand out for their commitment to academic excellence, entrepreneurial spirit, diversity, vibrancy, and creative innovation. Our team offers not only a healthy competition with contestants from all over the world, but also a 5-star tour service from Friday trip. The cities where we teach and do research are not just backdrops – they are also our classrooms, stages and laboratories.
With a world-class faculty that sets a global standard for academic excellence, the largest number of international students among Asia, and the largest number of students studying abroad, TIMO is among the most respected and desirable competitions in the world.
Different from other Mathematical Olympiad competition, every candidate will have his / her own evaluation report that will show the strength and the weakness of the candidate on topics such as Logical Thinking, Algebra, Number Theory, Geometry and Combinatorics. They can develop their own learning strategy in the future.
We welcome you to participate in the endless opportunities in TIMO, bringing together Mathematically talented children who have been drawn from all over the world to be taught, perform, create, and study in a place where everyone belongs.

Thailand International Mathematical Olympiad (hereinafter referred to as “TIMO Union”)TIMO is organized by Olympiad Champion Education Centre from Hong Kong. Mr Andy Lam, founder of TIMO, who was a former IMO winner, got 2 A grades in HKCEE and 2 A grades in HKALE. He had 16-year Mathematical
Olympiad teaching experience. To stimulate and foster young people’s interest in learning mathematics, to strengthen the ability of their creative thinking, to widen their international perspective, and to promote the development of kindergarten, primary and secondary education and exchange of educational cultures throughout countries, now he integrated a Hong Kong former IMO winner team to organize TIMO. This year, TIMO committee members invited 14 regions / countries such as Hong Kong, China, Indonesia, Singapore, Malaysia, Thailand, Ukraine, Philippines, Kyrgyzstan, Iran, Taiwan, Vietnam, Myanmar, India and Cambodia to participate.

ONLINE TRAINING
Global Olympiads Academy brings a Math Enrichment program for younger kids (grade 1 to grade 8) for International Olympiads (AMC, AIMO, TIMO, WMI, HKIMO, SEAMO,PIMSO,AMC 8, Gauss, etc.) The program will help the students strengthen their fundamentals, application and problem-solving skills and their overall higher order thinking skills like logical and analytical thinking. This course with Global standards (inspired by Common Core, Singapore Math and Indian NCERT curriculum) will not help students overcome fear with Math but would inculcate ownership, rigour and perseverance and most importantly liking for the Math. This will help them improve their academic performance in school and definitely in any competitive exam and lay a strong foundation for preparation of entrance exams in future.
