You are going to college and there is no booze allowed.
RIGHT !
Back in my college days I found a small tool box with hammer, screwdrivers, pliers, adjustable wrench a few assorted nails and screws and, of course, duct tape to be handy. There is always something you need to fix or tear apart. Make sure you know the dorm rules about what you can and cannot use to attach things to the walls.
A SAK and a multitool are always handy. A flash light is very high on the list.
