The problems that the participants tried to solve during the blitz contest are now open to the public. It is also possible to assess the keys.
The blitz contest consisted of 80 tasks, 20 for each general discipline (physics, chemistry, mathematics and informatics). The level of difficulty was similar to that of a school graduation exam. The teams had 2 hours to solve the problems. All the tasks were handed out simultaneously and disciplines were not signed.
The results of the competition have already been published. The blitz contest is a warm-up of sorts before the principal parts of the Olympiad. Its results do not influence the general count.
