My high school had kind of an unusual schedule—or at least I think it was unusual, but maybe you can tell me. There was no such thing as a lunch period or study hall. Instead, each class only met four days per week instead of five: for example, maybe your French class didn’t meet on Tuesdays, your Geometry class didn’t meet on Thursdays, your Biology and P.E. classes didn’t meet on Fridays, and so on. This meant that you usually had one or two free periods—or “X periods”, as they were called—built into your schedule each day, and during these periods you were allowed to do whatever you wanted. You could eat lunch, work on your homework, wander the halls, check your email at the email station (I went to high school in the late 90s, guys), or simply walk out through the front doors of the school and go off-campus.
