Grand Finale

The four remaining beauties and geeks go back to school to be graded on a variety of subjects including science, home economics and physical education. The team that receives the lowest average grade of all of the subjects is eliminated, and the other three teams are invited to the school formal, where the geeks have to stand in a kissing booth and be advertised by their beauties to the formal's other attendees. After the teams perform in a dance battle, the guests cast their votes for which couple showed the strongest bond. The two teams that receive the highest numbers of votes then participate in a final quiz in the Elimination Room, where the team with more correct answers wins the A$100,000 prize.
