On November 19th, 4 teams of four students from ESO 2 and 3 take part in the Náboj Junior Competition. This competition organised by Trojsten, an Slovakian association which organizes maths, physics and computer activities for students of primary and secondary school. Moreover, it enjoys a close collaboration with Carlos University (Prague), Comenius University (Bratislava) and Jaguelonic University (Krakow).

This year, teams from Slovakia, Poland, Czech Republic, France and Spain have enrolled. All in all with a grand total of 994 teams. 

The competition lasts 120 minutes in which teams try and solve the most amount of exercises possible. As soon as a team determines the answer to a problem, they receive a new one, which are, at the same time, increasingly difficult as the students progress in the competition. 

These Naboj problems differ greatly from the routine exercises done in school which usually require the direct application of standardized methods: Naboj problems require of a slight degree of creativity and ingenuity. Success in the competition relies not only on the individual ability of team members, but also on their efficient cooperation.
