If I'm not mistaken tomorrow is the last day of the quiz, who has not had time yet, you need to hurry. The more participants, the more interest and thirst for victory

So some people still have a chance to participate, i wonder how many participants
I think that this information is not secret and after the end of the quiz the total number of participants and the names of the winners will be known. But in principle, you yourself can calculate their number.

I wonder how many people took part, quizzes everyone loves people, let's call it "free money"

As far as I understand in the quiz, you need to guess the people who will be on the team. Its not entirely clear where does the "free money". I think the one who analyzed the project and the candidates will receive a reward.
