Players are divided into 2 teams, these teams are permanent!
Before a challenge, both teams will have a Class Election, in which they nominate a Class President. They can do dice anyway, voting, dice roll, random, taking turns, etc. as long as majority agrees.
Both teams will then go head to head in a challenge based off a school theme. The winning team will receive immunity.
The winning team's Class President may choose one person from the other team, (except their class president), and that person will have immunity from elimination. If they have not chosen a person before voting for elimination starts, then nobody is immunted.
The losing team will then go to Detention Hall for an elimination and will have to vote off one of their players.
