A group of Filipino students made the nation proud after bringing home two Gold, seven Silver, and 10 Bronze medals, and a Special Award in Science at the 22nd International Mathematics and Science Olympiad for Primary School Students (22nd IMSO) held in Alor Setar, Kedah, Malaysia from Oct. 5 to 10.
Jointly organized by the Kedah State Education Department and Albukhary International University, over 650 delegates, including more than 350 student participants from 23 countries and territories, took part in the prestigious event.
Leading the Philippine medalists were Wilzent Brian Lim (Grade 6, Pangasinan Universal Institute, Mathematics Division) and Leonard Vash Cay (Grade 6, Xavier School Nuvali, Science Division), who both won Gold.
Leonard Vash Cay's performance also stood out by claiming one of the six special awards, earning for him the Overall Best in Theory Award in the Science Division. This award is given to the student with the highest theory score among all science participants.
This makes him the only Filipino to receive a special award this year.
Cay's win is a major achievement for both him and the country, as the other top Science awards (Overall Champion and Best in Experiment) went to two students from Singapore, while in Mathematics, two students from Singapore (Overall Champion and Best in Theory) and one from Thailand (Best in Exploration) claimed all three special awards.
Meanwhile, the seven Silver medalists represented both Mathematics and Science divisions, showcasing exceptional academic strength:
Mathematics Division:
• Elizur Daniel Añabieza – Grade 6, Divine Light Academy – Bacoor
• Alistair Ivan Siahingco – Grade 5, Saint Jude Catholic School
• Ezekiel Anton Tan – Grade 6, Pangasinan Universal Institute

The Philippine delegation was led by Renard Eric Chua and Joel Edward Cardinal for the Mathematics Division, and Ivan Lawrence Aguilar and Jay Gabata for the Science Division.
The delegation said the IMSO stands out as one of the world’s most prestigious competitions for primary students, challenging young learners through a combination of theoretical and practical problem-solving rounds.
The Mathematics Division includes short-answer and essay tests along with an exploration component focused on puzzles and logical reasoning.
The Science Division features two theory exams and one practical experiment, encouraging both knowledge and scientific inquiry.
This year’s event brought together participants from Bangladesh, Botswana, Bulgaria, China, Ghana, Hong Kong, India, Indonesia, Iran, Kazakhstan, Laos, Malaysia, Mongolia, Morocco, Nepal, Philippines, Singapore, Sri Lanka, Thailand, United Arab Emirates, United States of America, Uzbekistan, and Vietnam.
