What is Školjka?
Školjka is a web archive of math problems, a tool intended for primary and high school students training for math contests. It contains thousands of problems from various math contests in recent two decades.
Why Školjka?
Školjka supports searching by categories and difficulty, allowing students to quickly find the exact problems they are interested in. Likewise, Školjka can be helpful to mentors and teachers for preparing lectures.

Školjka in English
Dear math enthusiasts,
We have added an option to switch the interface language to English, in preparation of the next Marinada competition.
This is still considered experimental, as not everything has been translated yet. If you find any typos or poor translations, please send me a message.
Thanks!
