I chose to go on exchange to the Karolinska Institutet for a number of reasons. I wanted to broaden my experience of studying abroad, and sweden was quite different from other countries I have studied in. I also wanted to produce a good Bachelor's thesis and I completed that in the CMB with the Spalding lab. Finally KI's world class reputation meant that when the opportunity arose I had to apply for it!
I think the exchange information was good, however there was some miscommunication between KI and my home institution possibly due to this being the first year of the exchange program happening.
