There is not much flexibility in the class schedule for the core classes. With the electives there is slightly more room to move things around depending on which one you choose. The nice thing about the scheduling is that most classes for the core major are scheduled around the same chunk of time in the day: morning, afternoon, and evening. For instance, having classes in the morning will most likely let a student be done for the day by 2:00pm most days. For those that don't start classes until 1:00pm or 2:00pm, they will likely be done for the evening around 8:00pm.
