CAT 2018 (non-printable PDF only) - All divisions
Computational and Algorithmic Thinking (CAT) is a great way to introduce students to algorithmic thinking without the need for programming skills. Algorithmic thinking, which involves developing a procedure or formula to solve a problem, is a branch of mathematics.
Some of Australia's most experienced teachers and computer scientists develop CAT problems. The problems are designed to be quick to solve and encourage students to develop informal algorithms and apply them to test data of increasing size or complexity. It includes six multiple-choice questions that are relatively easy to solve, followed by nine more challenging problems. Students have one hour to work on the problems.
Practising on past competition problems is an ideal activity for mathematics classes or individual students, to train for CAT or explore algorithmic thinking.
