It is no secret that to succeed in intellectual competitions, a participant not only needs to know the subject well but to understand the structure of the tasks.
For these reasons, we traditionally share with you demo versions of Olympiad questions. They give you an opportunity to study the structure of each section: the number of tasks, their form, the level of difficulty. We hope that the preparation will help you complete the tasks better, especially since this year we are sharing with you not one, but two sets of the qualifying round tasks for each age group!
Prepare a pen and paper, note the time, and go ahead: the demo materials are posted here.
