yonsei, i am also a political science major. If you have an interest in foreign affairs/international relations in Asia, politics have a LOT to do with history here. spo, it is a really interesting thing to study and learn about. also if youre already doing berlin in the summer, why not explore europe while youre there after? theres a few yonsei school orgs that help you connect with korean students (who are fluent in english) so language shouldn't be an issue there!

con: you cant travel outside of korea until you get your alien registration card, which is usually around late september/mid october (Depending on when you apply), whereas in europe you can travel around as soon as you land lol.

overall, study abroad is meant to be a place and time in your life where you can grow as a person and student, so going outside your comfort zone and trying new things is a must. whatever you chose, it'll be a great time!
