Many students shy away from numbers. However, mathematics is more than just homework for some students. It’s a challenge they genuinely enjoy. For these learners, equations are puzzles, and competitions are exciting opportunities to grow, solve, and connect. That passion recently led 35 students from IPEKA Christian School to qualify for the Grand Final of the World Mathematics Invitational (WMI), a global event to be held in Bangkok, Thailand, on July 25–29, 2025.
Representing IPEKA Christian School, these students have demonstrated outstanding problem-solving skills and a deep interest in mathematics. Therefore earning them well-deserved spots on the international stage.

To sum it up, competitions like the World Mathematics Invitational (WMI) go beyond academics. Firstly, they help build confidence, encourage global perspective, and give students real-world opportunities to grow. Secondly, for families and educators alike, these milestones reflect the heart of a Christian school education—where knowledge, character, and purpose are developed together.
