In what twisted world do you change lessons every seven weeks?

When I was at school, we studied all subjects, all year.

Business College.

My highschool only did four courses a day for a semester and then changed to a new course load after that. As for college, my program has a max of maybe six courses per term, but that's including General Education course which are generally a write off. I am a special situation personally as I previously attended a university before dropping out so I had credits to transfer allowing me to reduce my course load.
