how to school hallway (and how you shoud not)

in smith you aren't allowed to run in te hallways, or move faster than "legal school speed" and i have conducted a test where i went the maximum legal speed right when the bell rang but i was still at least 10 meters away from my classroom when i was considered late. therefore, 

YOU MUST RUN, PUSH, AND SHOVE IN THE HALLWAYS 

IF YOU WANT TO GET TO CLASS ON TIME.
