BoA once again met with the trainees to announce the next challenge. The trainees were tasked to perform live in groups based on positions they wanted to debut in: vocal, dance or rap. There were five songs for vocals (I.O.I's "Downpour", BTS's "Spring Day", BoA's "Amazing Kiss", Black Pink's "Playing with Fire", and Jung Seunghwan's "If It Is You") four songs for dance (Jason Derulo's "Get Ugly", NSYNC's "Pop", Ed Sheeran's "Shape of You", and Flo Rida's "Right Round") and four songs for rap (Mino ft. Taeyang's "Fear", iKON's "Rhythm Ta", Zico's "Boys and Girls", and Simon Dominic, G2, BewhY, and One's "Who You"). Each song had a member limit and would be picked by each trainee based on their ranks: Park Jihoon who ranked 1st from the first elimination round would have the privilege of choosing the song he wanted to perform first. BoA also announced that only 35 trainees would remain in the next round and that the winner from each position category would receive 100,000 votes while the winner from each group would receive 10,000 votes. After each performance, they were ranked by their groups first and then overall in the category. On the day of the stage performances, Super Junior's Leeteuk substituted BoA to host the show due to the latter's prior commitment. Only six groups were covered this week, with "Shape of You" group receiving the show's first-ever encore call.
(*) Ha Minho left the show shortly after the groups' performances were filmed due to some controversies.
