Previous IM²C problems

The IM2C has been held since 2015. We include the problem of each year's challenge, along with solutions and a summary of the national and international judges’ commentary on each. From 2016 onwards problem resources also include comments from Australian judges and videos made by members of award-winning teams to share their challenge experiences.
