The middle weekend of the summer school begins with Challenge Day. Each course is charged with a challenge related to the course of study. Our Young Doctors spent the afternoon at the hospital diagnosing patients while our Law Academy visited the Oxford Crown Court for a mock trial. The Psychologists prepared and run a study and our Engineers built a bridge. The Creative Writing class spent their challenge planning out a book series. The Leadership and Debate and Public Speaking classes battled it out in a Model United Nations while our Enterprise class pitched mobile app ideas to a panel of dragons. With everyone buzzing and exhausted from a day of hard work, we settled down to a relaxed evening. The traditional British style quiz gave the opportunity for teams to gain important points for the ongoing competition, and to review and comment on staff baby pictures. The day ended with a movie and free time before bed time.
