Teams were instructed to develop a system to minimize wait times while maximizing the use of available space. The group representing St. Francis DeSales worked efficiently to refine and explain their design.

They also competed in a Presentation Challenge, Multiple Choice Exam and Design/Build Challenge. The United States and Europe had 194 teams participating in the event.
