Obviously I have no way to give you specific advice on what exactly to pack, but I can give you some general tips. First, read through your study abroad acceptance packet. My packet through ISEP told me exactly what would and would not be provided by the university. For example, my first semester placement does not provide bedding. Then, I, rather quickly in this case, decided whether or not it was feasible for me to pack this particular item: nope. And so the process continues until you have established what you can and cannot bring with you.
I have attached here a copy of my initial packing list to show you how I tried to plan ahead by designating specific items to pack so I could keep them set aside; helping me to visualize what I was bringing along. Obviously though, whatever works for you is what you should do.
I recommend clicking on the image and zooming in so that you can actually read it (=
