Basic Info
Co-Ed School debuted under the Core Contents Media label in fall of 2010. The group originally had 10 members: Soonmi, Kwanghaeng, Yoosung, Taewoon, Kangho, Chanmi, Noori, Hyoyoung, Hyewon, and Sungmin.
The group released one album and went through several line-up changes as the group split into two sub-units: 5Dolls (female members) and SPEED (male members). In 2013, Core Contents Media announced that 5Dolls and SPEED were no longer sub-units, but independent groups, rendering Co-Ed School inactive.
