The Bebras International Challenge of Informatics and Computational Thinking has collected an increasingly large number of tasks. Every year more than 200 new task proposals are submitted of which many are accepted into the task pool. Properly categorizing these tasks to facilitate the use in the national challenges and to reuse them in the future is a challenge in itself: the categorizations in the past were biased and only covered certain aspects. Because the tasks are meant to be used everywhere in the world they are supposed to be solvable by students without any particular knowledge in computer science. General knowledge or skills may be assumed, though.
