There too many people trying to get down one stair well at one time.
Every one wants to get to their locker and get on the bus on time. A way to help every one get to their lockers and to the bus on time is to use more than just the one stair well. It might be a longer walk but in the long run it will be faster. Preston can help with this problem by encouraging some classes to go down the middle stair well. That will reduce the amount of kids trying to get down the center stairs.
