I participated on the National Olympiads in Informatics in Portugal, where I live. There was a first phase online, and then a second (final) phase in Porto. From the ~60 participants, only 30 qualified for the final. I got 10th. At the final qualification though, I got 19th, and only the first 4 get to go to Italy this year, for the International Olympiads in Informatics. I can still participate next year, for a chance to go to Australia. Even though it didn't go out that well this year, I learnt a lot, and it was a very amusing experience. Oh, and I learnt lots of stuff, like Dynamic Programming, Divide And Conquer, Kadan's Algorithm, DFS & BFS, etc. Highly recommend it!
