Have you participated in subject-specific Olympiads?

Once, I participated in a city-wide history competition, took 1st place, and won a video player. This was when I was in 8th grade, and a video player was a huge deal back then. However, the principal confiscated it and put it in the history teacher's office, claiming it was the teacher's merit for teaching me. In the same year, I switched to a different school. Later, in 10th grade, I participated in a history competition again, but I only got an honorable 4th place. The certificate is still somewhere around. I also participated in an English competition sometime, but I didn't win anything. Oh, I remember, in 10th grade, I also participated in a law competition and took 2nd place in the city. Those are all my achievements.
