2011–2012: Formation and debut

In 2011, Core Contents Media announced that they would be dividing Co-Ed School into two sub-units. The first unit consisted of the original five Co-Ed School female members and one new member; together they would form 5Dolls (commonly stylized as F-ve Dolls). They debuted in 2011. The second unit consisted of the original Co-Ed School male members Kangho, Kwanghaeng, Jungwoo, Taewoon, Noori and Sungmin. On November 4, 2011, it was announced that member Kangho had withdrawn from the group to focus on an acting career. Core Contents Media also announced Superstar K3 contestant Shin Jongkook would replace Kangho. In January 2012, Core Contents Media revealed the second sub-unit's name would be Speed (commonly stylized as SPEED). The group released a single album, Hommage to Lovely-Dovey, with the title track "Lovey Dovey-Plus" on February 14. The song was a remake of T-ara's hit "Lovey Dovey". The music video featured Ryu Hwayoung and Ryu Hyoyoung. On February 14, Speed made their first live performance with the song "Lovey Dovey-Plus" on Music Bank. Sejun was added to the unit a few days later. In early 2012, Core Contents Media moved Co-Ed School and its sub-units to their subsidiary label GM Contents Media. Near the end of 2012, the group was moved back to the main label Core Contents Media, along with F-ve Dolls. Members Kwanghaeng and Noori left the group in September, and were replaced by Yuhwan and Taeha in October. 2013: Superior Speed
In late December 2012, Core Contents Media announced that Speed would release an album entitled Superior SPEED. The group pre-released a single album, Speed of Light, with title track "Sad Promise" on January 7 along with two music videos to the song, a dance version and a drama version.

On January 15, Speed released their debut album, Superior SPEED, and its title track "It's Over". "It's Over" also got both a dance version music video and a drama version music video.

In mid-2013, Core Contents Media stated in an interview that they had no plans for Co-Ed School to reform again as both of the sub-units had grown and changed their line-ups to become independent groups. 2014: Mini concert and Speed Circus
