Coed School (Korean: 남녀공학) was a South Korean pop group formed by record company Core Contents Media in 2010. The co-ed group consisted of four female members: Sumi, Hyoyoung, Hyewon, and Chanmi; and six male members: Taewoon, Sungmin, Jungwoo, Kwanghaeng, Kangho, and Noori. The group was eventually divided into two sub-units: an all female-group called F-ve Dolls (2011) and an all-male group called Speed (2012).
