co-curricular activities. A given class may meet all four days, but need not meet for the same amount of time nor even begin at the same time each day. However, some classes may meet three, two, or in some special cases, only one day per week. Generally, A & C days have the same schedules and B & D days have the same schedules, although for students, usually sophomores, this is not the case. The pattern for each class is usually reduced to a pair of numbers: a 3-2 class meets for 3 mods on A and C days, and only 2 on B and D days, while a 0-4 meets only on B and D days, for 4 mods each day. As a result, there is considerable variation as to how many classroom minutes each course has per week:
