Event List
Events are divided into B Division and C Division, for middle-school and high-school teams respectively. Each division has 23 events, which may be shared across divisions. Most events are designed for up to two students and, while a single student can participate, they will be at a disadvantage. With only 15 students to a team, scheduling your team can certainly be challenging.
Typically, a group of two students should train in 3-4 events. (15 students/2 students per event = 7.5 groups; 23 events/7.5 groups = 3.07 events per group) Once registration has opened for the upcoming competition, you will be able to select one of several sections for each event. Carefully choosing non-overlapping sections in which your groups have been training is going to crucial to your team's success overall.
