The CSO22 has three age brackets: under 16s, 17-19, and 20-25 years old. Regardless of age, participants compete in the same qualifiers and answer the same type of problem statements. However, we only compare participants within their age brackets. This means we score the three brackets independently and normalise scores within each. Semi-finalists, finalists, and winners are those with the highest normalised scores. This ensures fair comparison regardless of age.

Registration for qualifiers ends on August 10th, 2022

You can participate up to 3 times plus once for every referral you make.

Only 10% of participants will advance to the quarter finals and 10% of those to the semi finals, so preparation makes a major difference. You can take our courses or complete our quizzes in the app. Beyond that, read about whatever you are interested in and describe your solutions during the event!

Prize Money: – First place wins $5,000 – Second place wins $3,000 – Third place wins $2,000 – Participants ranked 4th through 7th win $1000 each and 8th through 10th take home $500. All figures in USD. Winners will also get a chance to speak at the Award Ceremony, hopefully to be conducted at COP27, just like in 2021.

Results for qualifiers and quarter finals are instant via our UI and via email. Semi finals results will arrive close to the finals date. Please do not send us emails asking when results will be announced.

Schools can choose to run qualifiers digitally or on paper. Paper participation will launch in late February 2022. Schools that participate digitally need one computer, laptop, or phone per student (students can use their own devices too) and one computer for the teacher leading the event. Teachers need to follow procedures for timing, ensure no cheating, and collect responses securely after the event ends.
