The guidelines to participate in the International Junior Science Olympiad are set in place to ensure a fair and fun competition. Competitors in the International Junior Science Olympiad swear an oath at the beginning of the competition to answer the theoretical an practical competition questions in the most responsible way and to compete honestly and fair. Apart from the intention to play fair, the set of rules and guidelines listed here applies to all participants.
1) Participants must agree with and accept the conditions as stated in the statutes from IJSO. A pdf document with the statues can be found at: http://www.ijsoweb.org/qna/Statutes20140324.pdf

The complete solution of each problem must also be submitted.
