Jang Geunsuk once again met up with the trainees to announce the next challenge. The trainees were tasked to perform live in groups based on positions they want to debut in: vocal, dance, or rap. There were six songs for vocals (Big Bang's "Monster", EXO's "Call Me Baby", Huh Gak and John Park's "My Best", GFriend's "Me Gustas Tu", Zion.T's "Yanghwa BRDG", and Tashannie's "Day by Day"), four songs for Dance (EXO's "Growl", Jessie J, Ariana Grande and Nicki Minaj's "Bang Bang", Destiny's Child's "Say My Name", and Sunmi's "Full Moon") and three songs for Rap (Verbal Jint's "You Look Happy", SMTM4's "Turtle Ship", and IKON's "Rhythm Ta"). Each song had a member limit and would be picked by each trainee in order of their ranks. In which case, Jellyfish Entertainment's Kim Sejeong had the privilege of choosing the song she wants to perform first and Happy Face Entertainment's Hwang Ayoung was automatically placed in the empty remaining slot. Jang Geunsuk also announced that only 35 trainees would remain in the next round and the winner from each category will receive 100,000 votes added on to their current votes. The vocal teams were the first to perform and after each performance, they were ranked in their groups first and then overall in each category. Kim Sejeong emerged as the winner in the vocal category.
