Oxford University Computing Challenge (OUCC)

First round: Wednesday 5 May 2021
Second round (invite only): Wednesday 12 May 2021


Cost: A$6.50 (or A$10 as a bundle with CAT)
Entries close: 30 April 2021
Bundle entries close: 1 March 2021


The Oxford University Computing Challenge (OUCC) builds on the principles used in the Computational and Algorithmic Thinking (CAT) and helps students develop their skills further to produce programmed solutions to computational thinking problems. They will tackle problems using the Blockly programming language, as well the programming languages available at their schools for secondary levels.

The OUCC is a two-round online competition held in term 2. The first round (5 May) is open to all students in years 5–12 and the second round (12 May) is an invitational for the top 20 students in each division from the first round. It’s perfect for students who have previously done well in the CAT and those who’d like to progress to the Australian Informatics Olympiad (AIO).

Each round consists of three sections. The first two sections are of five tasks each and the last is of two tasks, with the complexity increasing with each section. Students have one hour to complete all tasks within sections one and two and attempt the tasks in section three.

The four divisions are:

Upper Primary – All tasks will be Blockly tasks
Junior – All tasks will be Blockly tasks
Intermediate – Some tasks in sections 1 and 2 may be Blockly tasks
Senior – There is one Blockly task in section 2

What happens if there are COVID-19 school closures? 

We will refund schools that are unable to run an AMT competition in 2021 due to COVID-19 government-mandated school closures. In some cases, we may also offer an official competition second round.
