Mikhail Putilin, Russia:
This is my second time at this Olympiad. Last year I won a gold medal, and this year I hope to do the same. Our team’s mascot is a hedgehog. A few years ago at the All-Russia Olympiad there was a question called “The hedgehog in the fog”, which we all really liked, and so we decided to make a
hedgehog our mascot. I hope our team wins gold medals this year, but at the same time I want to wish good luck to all the other contestants!
