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

The Oxford University Computing Challenge (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 is recommended for students who have previously done well in the CAT and would like progress to the Australian Informatics Olympiad (AIO)

The OUCC builds on the principles used in the CAT competition and helps students develop their skills further to produce programmed solutions to computational thinking problems. Questions are solved using the Blockly programming language, as well the programming languages available to students in their schools for secondary levels.

Each round consists of 3 sections – the first two sections are of 5 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 section 1 and 2 and attempt the tasks in section 3.

The four divisions are:

Upper Primary – All tasks will be Blockly tasks
Junior – All tasks will be Blockly tasks
Intermediate – Most tasks in Sections 1 and 2 will be Blockly tasks
Senior – Some tasks in Section 1 will be Blockly tasks

  • Strings, Output and Input
  • Mathematical and Logical Operators
  • Conditionals
  • Loops
  • Functions
  • Lists and Arrays
  • File Input/output – Intermediate and Senior only
  • Classes and Objects – Intermediate and Senior only

Syllabus Area Two

  • Logical Thinking
  • Algorithmic Thinking
  • Decomposition
  • Pattern Identification
  • Abstraction
  • Evaluation
  • De-bugging
