I was very happy that I did go (and to be accepted) to the exchange program. I learned a lot, but besides gaining important academic skills and knowledge, I feel that the most important things were learning more about Asian culture, people and food - some things you cannot just read about, but you have to really _be there_ for a time being to experience it yourself.
As a student I enjoyed the possibility to participate in real work at a research lab, to visit local hospitals and talk with the professionals. Also the course I took complemented nicely the studies I had some at KI - even if the topic was something I had learned already, the angle and approach was different and I feel the combination will serve me well.
But first and foremost it was nice to live in a new continent for one semester, and to experience it first hand. It was a kind of Zen'ish experience, not to have too much stuff or too much to do, so I had time to read, walk and just to think about things. I guess I did also eat and drink healthier (as there are so many good options, like the freshly squeezed fruit juices made to order for about 10kr at the cafeteria at the Uni), as it wasn't as expensive as in Sweden.
So, in hindsight, would I go if I had known what I know now? Absolutely. And actually after Singapore I wrote an email and got invited to work as an intern researcher in another famous research group in Europe for the summer (I got the idea about that while still being in Singapore) - something that I probably hadn't even thought of if I hadn't gone there. So, looking back, I cannot imagine all the things I had or would miss if I hadn't had the exchange experience; it's now an integral part of me :)
