Exchange is something that everyone should try out either in college, high school, or after college, doesn't matter. Lots of fun and you have no idea how many brilliant people you will meet :) choose a culture you are Interested in. As normal as this sounds, if you choose a country you are iffy with, your time is not as great as if you chose a country you adore. It's about immersing yourself into normal life elsewhere, easier to do if you're happy with the country amirite. Point being have fun, if you're not having fun, change something. Don't force yourself to do anything because it's meant for the program, do it for you and for the people you're with and love.
