The WinterChallenge (WiC) is an online competition created by the IEOx Community for everyone under the age of 21. Its aim is to help high school students challenge their knowledge of economics and get familiar with the real IEO. 

The WiC structure is similar to the IEO and consists of three rounds: the Financial Literacy Game, the Economics Test, and the Business Case. Unlike in the actual IEO, the Business Case round in WiC is divided into two stages: 

1) peer-grading (all cases); 

2) graded by the professional jury (cases that advance to the finals).

Next IEOx WiC to be held in February, 2026.
