(Oh, the high school block schedule? XD
http://fch.psdschools.org/schedules/bell/times'Even' days and 'odd' days switch in some fashion. If Monday gets periods 1, 3, 5 and 7--- then Teusday will have 2, 4, 6 and 8. The classes are around and hour and a half long, and lunch is in the middle of the day. Students, if they map out their classes right, can have as little as 5 classes for senior year. In Alex's case, he must have taken most of his credit classes in earlier years so he can take 5 classes instead of 7 or 8.
At least, that's how it worked at my high school. Schedules vary from school to school...
....May we skip to the end of the day? XD)
