 * Italics indicate that the act was either chosen to move on or eliminated in the Judges' Choice, which means they finished in either seventh or eighth in America's Vote.

Process
From the 36 Quarterfinalists, 12 acts performed each week over three weeks. Each week, 7 acts moved onto the Semifinals.

The contestants that came in sixth, seventh, and eighth place in America's Vote fight for votes online in the Dunkin' Save. The act who received the most votes earned a spot in the Semifinals. The judges voted between the two remaining acts the last spot of the week in the Semifinals.
