There are three fixed participants in the mathematical model competition, one of whom is the captain, who can form a team across schools and sign up for it.

However, it will be a little troublesome after winning the prize in a cross-school team. Captain's school needs a cross-school team certificate to start school. Moreover, if the teams from different schools are far away, it will be more troublesome to cooperate in the competition, so if our school has suitable candidates, it is best to find the team from our school.
