Bad But Good, a four-song EP, was released on July 1, 2010. The EP included "Love Again" ("다시 사랑") and "Bad Girl Good Girl", which served as Miss A's first and second singles, released on June 30 and July 1, 2010, respectively. These two tracks plus album track "Break It" were later included on A Class; the track "Looking At Each Other" ("딱 마주쳐)" was not included. The group had their debut performance on July 1, 2010, with "Bad Girl Good Girl" on M.net M! Countdown. A second four-track EP, Step Up, was released on September 27, 2010. Its track "Breathe" was used as the promotional single, and all the songs were later added to A Class. The "Breathe" music video shows the Miss A members dancing in a room with stripes of various colors. The members are also shown standing around a large cannon from which member Jia is about to be fired. In July 2011, Miss A announced the upcoming release of their first full-length album called A Class. JYP CEO Park Jin-young uploaded a video of himself at a recording studio with Grammy-winning mixing engineer Manny Marroquin, who has worked with artists like Whitney Houston, Alicia Keys, Kanye West, and Bruno Mars. He also showed a 15-second preview of the group's new song "Goodbye Baby", which eventually became the album's lead single. The single was released on July 8, 2011, followed by the A Class album on July 18. The album's next single, "Love Alone", was specially created for South Korean figure skating champion Kim Yuna's "Ice Show".
