elementary school has one main teacher, middle school has many! elementary schools usually don't have lockers, middle school does there might be a little more homework, tests, and projects in middle school but it's not as hard as you think it is!
Middle school is hell. I couldn't deal with it anymore. Thank goodness I'm in highschool now which is way better. Anyway---Elementary school gets way more homework. However it's less stressful because you don't have to deal with as much drama and switching classes all the time.
