I had been to Stockholm 2 years before my exchange for a couple of days for holidays. I really enjoyed the city and its people. I decided to do a swedish language course and because this was so much fun, I decided to go to Sweden for exchange. Because of KI impressive international reputation the decision was easy to make.
The information given from both sides was good, I received all the information needed.
Especially the possibility to apply at UAC for an appartment was very good so I felt prepared for my exchange when I arrived.
No special certificates were required, but I think that the MRSA-test which was done during the introduction days is an important procedure.
