The seven remaining beauties and geeks go back to school, where the beauties have to teach a Year 7 class one of four subjects - physics, chemistry, biology or vulcanology. The geeks then pair up with their beauties to choreograph and perform a cheerleading routine, from which the best two couples compete with a professional team of cheerleaders. The winners of the two challenges each nominate a team to send to the Elimination Room, where they participate in a quiz in which the team with fewer correct answers is eliminated.
