Kangourou sans Frontières (KSF)

What teachers and students think

Kangourou sans Frontières (KSF) is on Thursday 18 March 2021

Entries close: Monday 15 March

Cost: A$10 per student (with AMC entry)

In 1991, two French teachers inspired by Australia’s AMC decided to start a similar online competition in France. They called it the “Kangaroo” to pay tribute to their Australian friends.

The competition was a big hit and has since been adopted around the world. It is now known as Kangourou sans Frontières: (Kangaroo without borders). It is now one of the largest international mathematics competitions in the world, with more than 6 million participants annually.

In Australia, Kangourou sans Frontières (KSF) is an online maths competition for years 3–12, and may only be entered by schools also competing in the Australian Maths Competition.

KSF contains multiple choice questions. All papers have 30 questions except Middle Primary, which has 24. All questions are multiple choice (there are no integer questions). The two primary papers are 60 minutes. The high school papers go for 75 minutes. KSF is not available in paper and pencil format: it is online only. For more information, see our KSF frequently asked questions.

There are free practice questions on our competition site to try.

It is a great lead-up event for the AMC and we offer a KSF/AMC competition “bundle” for $10 per student in 2021. Teachers only may register for the bundle below. Click below to create a co-ordinator account or use an existing account and then register your students.
