For when there actually was school, how much time is in between each of your classes? (Question only for public middle-high schoolers.) For my school, you get 3 minutes between each class to leave, go to your locker, put that classes materials away, get materials for your next class and go to your next class. Since I am not usually quick enough to do so, i carry my bag to different classes until lunch (my first 4 classes do not care if you have your bag) and I put my bag in my locker. I keep my science (6th period, no bag allowed) notebook in my computer case so I don't have to go back to my locker beforehand, if I do I am late. The only class I ever need to go to my locker for is my last one (two, 7&8 are the same class), reading/English (it alternates the classes per week) I need my books and binder.
