C#, PHP, Python 2 and Pascal are no longer officially supported languages in the AIO. The only official languages are C, C++, Python 3 and Java.
If you would like to compete in a different language, please email us at firstname.lastname@example.org.
The AIO Handbook PDF has been retired. The contents have been moved onto this website.
Like last year, schools who are under stay-at-home restrictions can have their students sit the AIO at home.
Supervisors need to use a video conferencing program to make sure students are at their computers during the competition.
