During the day of the PI number there was a 5^th grade student’s competition. The three teams had to answer 15 questions-  8 of the mathematical and 7 – in English. They can pile up points between 5 and 1000. The public also took part in, because the participants could use 3 jokers. As usually there were a lot of funny and stressful moments. The “most knowing” students were 5^th B, “more knowing” were students by 5^th A, and these ones who “knew” the material were students by 5^th v grade.
