About MyJSO
MyJSO is an annual national-level competition in the Natural Sciences — Biology, Chemistry, and Physics — for students under sixteen years old. It is the next stage for top Kancil Science Competition performers, and Malaysia's selection pathway to the International Junior Science Olympiad (IJSO).
The next chapter after Kancil Science
MyJSO is an annual national olympiad in the Natural Sciences for students under sixteen. It picks up where the Kancil Science Competition leaves off — testing the country's strongest young scientists across Biology, Chemistry, and Physics.
Performance in MyJSO determines who joins Malaysia's national team for the International Junior Science Olympiad (IJSO) — a global stage that has historically welcomed delegations from over 60 countries.
