"Come together. Over love in Mathematics"

There is great enthusiasm among Primary students to compete in mathematics competitions. This is an extremely good sign for the progress of mathematics education.


However, most mathematics competitions seem to be testing students' knowledge beyond the school syllabus and exposing what the students cannot do while a mathematics competition should actually be a platform to reveal what students can do!

ISMC aims to encourage the young students to compete at the international level. It also helps to identify best talents among students. Its syllabus is mainly common with the Singapore Maths (Primary) syllabus. Thus, students can take part in ISMC without advanced beyond-the-grade-level knowledge and marathon of special training trying to learn in hours all topics which are new and unfamiliar to them.
