Introduction day is really awesome, because that is the day you start to meet all the new students i.e. exchange students. We generally found out that mst of us, if not all, will be staying at either Strix or Pax which are accomodation buildings very near to the campus Solna. The school also handed out a free bag for each which I carried mine to school daily, the bag really came in handy. Maybe they could include one laptop bag. Thenafter, we had welcome dinner by MF (student union of KI) which was fabulous. The entire arrangements made us feel very welcome, and easy.
I didn't contact any student health centre work.
