On Wednesday 22 May, around 100 students completed the Computational and Algorithmic Thinking (CAT) competition. It gives students the opportunity to develop their problem-solving skills through algorithmic thinking. The competition incorporates unique ‘three-stage tasks’ that encourage students to develop informal algorithms and apply them to test data of increasing size or complexity. There are three divisions for the students: Junior (Year 7-8), Intermediate (Year 9-10) and Senior (Year 11-12). Well done to all the students who took part in this online competition.
