Our mathletes were guided to the Philippine International Mathematical Olympiad Final Round 2025 by Math Subject Area Coordinator Grace Yn; Primary 3 coach Rachelle Suba; Primary 4 coaches Rose De Jesus and Patrick Ablang; Primary 5 coaches Rose Perfecto and Guada Barcelon; and Primary 6 coach Javier Inumerable.

The Philippine International Mathematical Olympiad (PhIMO) is a highly prestigious international mathematics competition for students from Kindergarten to Grade 12. It aims to identify and nurture young mathematical talent while promoting academic excellence, discipline, and global camaraderie through friendly yet highly competitive problem-solving.

The PhIMO Final Round is the culminating stage of the competition, open only to students who qualify through earlier elimination rounds. Participants tackled rigorous, non-routine mathematical problems that tested not only computational skill but also logical reasoning, creativity, and problem-solving under time pressure. Contest problems were aligned with international math olympiad standards and designed to challenge students well beyond their grade level.

This year’s onsite competition was held at the Cebu Institute of Technology – University (CIT-U) Atrium in Cebu City, Philippines, where hundreds of qualified mathletes gathered for the face-to-face exams and events. The awarding ceremony and related celebrations followed at JPark Island Resort and Waterpark in Lapu-Lapu City, Cebu, providing a vibrant and memorable setting for recognizing participants’ achievements. 

According to local reporting, the Final Round attracted a large pool of competitors, a significant increase over previous years. The elimination stage leading up to the Finals saw thousands of students competing, with approximately 1,700 onsite participants at CIT-U joined by about 2,000 students competing online — reflecting a hybrid format that widened participation across regions and countries. 

The Final Round is the culminating stage of PhIMO, open only to students who qualify through earlier elimination rounds. Contestants faced challenging, non-routine mathematical problems designed to test deep reasoning, creativity, and problem-solving skills at an advanced level. This stage emphasizes rigorous academic standards and often mirrors the structure of international math olympiads, making it not only a competition but also a critical learning experience for young mathematicians.

In recent years, PhIMO has drawn participants from more than 15 countries, including the United States, Australia, Japan, South Korea, Thailand, Canada, and Vietnam, underscoring its growing international stature. Medalists in the Final Round are recognized among the top young math performers in their respective categories, making AGS’s strong showing a testament to the school’s sustained commitment to excellence in mathematics education.
