Question

This year, Yossi participated in the Mathematics Olympiad for the first time. Before the Olympiad, a survey was conducted in which each participant was asked what place they thought they would achieve. Yossi answered that he would probably be in last place. After the competition itself, it turned out that every participant, except for Yossi, achieved a worse place than they answered in the survey. What place did Yossi take in the Olympiad?
