How do I register for the IOI?

Registration for the International Olympiad in Informatics (IOI) typically takes place through each participating country's national committee. If you are interested in competing in the IOI, you should contact your country's national committee for information on their selection process and registration requirements.

The IOI is open to secondary school students who have not yet started university, and who are under 20 years of age on July 1st of the year of the competition. Students who are interested in competing should have strong programming skills and a solid understanding of algorithms and data structures.

The IOI is a highly competitive event, and the selection process for national teams can be rigorous. If you are interested in participating, it is important to start preparing early, by practicing your programming skills and participating in local programming contests.
