Hmmm... let me see if I can remember.

Grades 1-6 (primary school) each grade had their own classroom and we stayed in that all day, with the exception of gym.

Middle School (Grades 7 and 8) We got lockers, and each subject had its own room. I think they were trying to prep us for high school. Our class stayed together as a unit, but we rotated between rooms. With the exception of Gym, then our class was split between boys and girls. So when the boys had the gym, we did health studies, and visa versa when we had gym.

High School (9-12) was pretty typical of any other highschool in our area.
