Try to only pack what you think are necessities. Keep in mind that you will most likely purchase things there as well and need room to bring them back.

Are you going to want to leave every weekend?
do you speak the language?
housing options
Homestay, dorm provided, needing to find housing independently?
cell phone plan
make sure that your phone is fully paid off before you leave, otherwise the new sim card will not work on your phone
