Sometime after the performances and before the ranking announcement on May 12, BoA gathers the boys informing them about the coming elimination round (where contestants ranking 36 onwards would get eliminated). She then introduces the next challenge: Concept Evaluation. She introduces the five songs: Hyuk Shin's "I Know You Know" (Synth-pop/Funk), Veethoven, Oh Sunghwan, Kiggen and ASSBRASS's "Oh Little Girl" (Hip Hop), ASHTRAY & KINGMAKER's "Show Time" (Nu-disco), Devine-Channel's "Open Up (열어줘)" (Future EDM), and Triple H's "Never" (Deep house).
