what kinda retarded ass high school keeps kids in the same class all day?

ALSO, did you ever notice that sometimes when they DID switch classes, they NEVER showed them in any other class besides Mr. Kotter's?
What classes were they taking?


(and in related topics, the kids on "Saved By The Bell" at LEAST looked like High School kids. But The Sweathogs looked like they were in their 20's...)
