Bring comfy shoes for walking (more than one pair)

Make sure you have a suitcase/backpack for traveling on weekends and spring/winter break

Hairdryers, straitening irons, etc will probably break....you're better off buying a cheap one in london (if you have to have one)

The bagel place by the school is a good place for cheap lunches

Get a travel book (or several) and read through them before you leave
