Summary: At the Las Vegas callback auditions, 115 dancers compete. Every day the dancers learn new routines from different choreographers. After performing their routines they are scored by the panel of judges. The judges each have a scale of 0-3 points for each contestant.Contestants that score well are put through to the next round and the others are sent home. Those dancers that remain borderline after the results are asked to "dance for their life" - this means they have to perform a solo for the judges. After the solo, the judges make a decision to cut them or not.
