Lee Dongwook met with the trainees once again to announce the next challenge. The trainees were tasked to perform live in groups based on positions they wanted to debut in: vocal, dance, rap, or "X" . "X" was a new position that required trainees to perform two of the three aforementioned positions simultaneously. There were four songs for vocals (Paul Kim's "Me After You", Hwasa's "Twit", Bolbbalgan4's "To My Youth", and Wanna One's "Day by Day"), three songs for dance (Imagine Dragons's "Believer", Bruno Mars's "Finesse", and Jason Derulo's "Swalla"), two songs for rap (Zico's "Tell Me Yes or No" and Haon, Vinxen's "Barcode"), and two songs for "X" (Charlie Puth's "Attention", for vocal x dance, and SMTM4's "Turtle Ship", for rap x dance). Each song had a member limit and would be picked by each trainee based on their ranks: Kim Yohan, who ranked 1st from the first elimination round, had the privilege of choosing the song he wanted to perform first. The winner from each performance in the vocal, dance, and rap positions would receive 100 times their votes while the winner among all songs of each category would receive 100,000 votes. For the "X" position, the winner from each performance would receive 200 times their votes while the overall winner would receive 200,000 votes. After each performance, they were ranked in their groups first and then overall in the category. Lee Dongwook also announced that only the top 30 trainees will remain in the next round. Only five groups were covered this week. There were no eliminations this episode.
