Idol School

Episode 1

After the introduction of the show from the acting principal, the girls enter the classroom one by one. They begin their lessons with a vocal evaluation, singing "Into the New World". They then started dance lessons, where students must learn re-choreographed version of songs, with both songs' chorus looped on a cycle. At this episode, student Som Hye-in made the decision to leave the show due to poor health.

Episode 2

After the buffet-style lunch, they get a new dance break, where Song Ha-young and Natty won the dance break parts in the MV, thus becoming dual-centers of the mass dance. They also record the MV for the school anthem where they have to be able to capture their memorable "killing part". The students also saw a dance performance, which was for recording the promo video, where there are many intricate formation changes. In the MV taping the day after, they only have 3 chances to perform as a whole 40-student squad, or else, the 10 worst students would not be in the MV.
