---Not just command strip hooks but tons of the extra strips in various sizes. My roomie and I "mounted" our power strip on the side of our dresser for our alarm clock, hair dryer, and flat iron.
---Lysol and Clorox wipes. More i.e. And I forgot to bring this and before we would unpack we begged our parents to go buy about 4 cans of Lysol. We opened the windows and lysoled every inch of that dorm.
---we also bought shelf liner for drawers just to protect our clothes from old wood and metal
---if he's gonna have food to eat in room or take to microwave down hall to eat, a handheld can opener, microwave safe bowl and plate, a set of utensils and an oven mitt/hot pad
---not sure how bathrooms are, but we had 2 rooms that shared a bathroom and you couldn't lock yourself IN the bathroom. Me put a radio in there and if anyone went in (shower or use the facilities) we turned on the radio and you knew it was occupied. We also were able to put shower curtain on a shower curtain rod across where the commode was so in case someone needed to grab something or had guests that didn't know the radio rule, we still had privacy
---if they have their own shower, an over the spout caddy, corner caddy, suction cup caddy, etc to leave items in shower.
---power strips. We had regular ones and then there's one with a super long cord (like 10+ feet) in case we needed to stretch across somewhere
---a couple fold up camp chairs for company. We had lofted beds and 1 desk chair each and no sofa or bench. If anyone came over, we needed extra setting. Those camp chairs folded up and we could stuff them in our closest or a corner.
---we had 1 window with metal blinds, but room was warm so we got a spring rod and dark curtain to cool room
---as far as school supplies go, I liked hanging up a huge desk blotter calendar on the wall and wrote class stuff on it. I know kids rely on phones now for calendars and reminders, but I still love being able to turn and see. Same goes with a 1 subject notebook for each class to take notes.
