The tournament has three stages: qualifying, main, and final ones. Let's learn about them one by one!

The first one is the qualifying stage, where teams receive 20 video tasks from the jury. Each video task shows a specific phenomenon in Physics, Astronomy, Biology, Geography, or Chemistry.
Your team has 1.5 months to solve all of them. Then, you should fill in the answer forms and send them via the form on the Tournament website.

Let's move on!
The second stage is the main one. At this stage, the teams that scored at least 75 percent of the maximum number of points compete with each other. They receive 20 new video tasks, and this time they only have a day to solve them.

The three best teams make it to the final stage.

At the last stage, the teams meet in person. They get 5 tasks each and have to solve them in 5 minutes. The jury selects the winners, prize-winners, and laureates.

During the qualifying and main stages, teams are allowed to use any sources and ask for help from mentors. At the final stage, they use the Internet only to search for information.
