Rank of My Teenage Girl

Episode 1

Aired: Nov 28, 2021

Episode: 1


Ahead of the auditions, the four mentors of the program gave powerful intro performances, with Yuri performing to “The Boys” by Girls’ Generation, Soyeon to “Oh My God” by (G)I-DLE, Aiki to “End of Time” by Beyoncé, and Ock Joo Hyun to “NOW” by Fin.K.L. 

The first mission was an entrance exam that only 10 students of each grade would pass, leaving a total of 40 contestants. To pass the first round of the mission and be judged by the mentors, the contestants had to receive votes from more than 75 percent of the audience. If they got a pass from 75 percent of the audience during their performance, the barrier between them and the mentors would lift, and they would receive a second round of judging from the mentors.

Episode 2

Aired: Dec 5, 2021

Episode: 2


The first mission continues with performances by 26 contestants. During the mentors' assessment of one of the performing teams from Grade 2, Ryou Jayhyun was mistakenly eliminated after the voting system miscounted her votes with 2, but was able to move on to the second mission after another vote from one of the mentors was added to the voting system, leaving a total of 3 votes for Ryou Jayhyun. Unaired performances by some performing acts were aired with results for each performing act. Out of all 26 contestants who performed in this episode, 21 moved on to the second mission while the other 5 were eliminated after failing a round.

Episode 3

Aired: Dec 12, 2021

Episode: 3


The first mission continues with performances by the other 34 contestants. At the end of the first mission, the remaining contestants noticed there would be a change on the number of contestants who would move on to the second mission. Due to an excessive number of contestants, each group would have 16 contestants instead of the original 10 and some contestants who were originally eliminated returned to the show, bringing a total of 64 passers for the first round. The mentors held a meeting to discuss and decide who would mentor each group. The results for the mentors were revealed and were assigned a group: Jeon So-yeon became the mentor for grade 4, Ock Joo-hyun became the mentor for grade 3, Kwon Yu-ri became the mentor for grade 2 and Aiki became the mentor for grade 1. Following the addition of originally eliminated contestants, the second mission known as the "Grade Battle" was revealed. In the second mission, each group competes against each other and would be assessed by the audience and the mentors. The winning group is exempt from elimination and the other groups face elimination. After the mid-point check of each group, the mentors noticed only 40 contestants (10 from each group) would actually perform in the second mission, meaning they would be forced to eliminate 24 contestants (6 from each group) from the show. The 6 contestants from grade 2 who performed poorly in the mid-point check were eliminated first.
