I went on exchange at Georgetown University during Term 2 of my second year of study.
Apart from taking math courses that were related to my major, I also decided to take a course in their world-famous department of political science. I found the course both eye opening and challenging, and in the process of reading course materials and doing research for a 20-page essay, I learnt a lot about the history of various countries and how it came to shape their current political systems.
Although I was previously aware that sports are huge in America, I was still surprised by how it permeated every level of their culture, from the popularity of sports bars to the occasional sports reference in everyday conversations. I realise that whilst you can read about other cultures, there is still no better way to truly understand them than to experience them for yourself.
