Length: +/- 2000 words
Topic: Sports + culture/politics/ethics/sociology (not necessarily in Spain, feel free to write about a US topic as well). Take a topic that is very specific, there is no topic that you can’t write 2000 words about! But a topic that is too broad will not allow you to write a decent paper!
Referencing: Every fact/claim in your paper should be referenced. Use the system that you are used to at your home campus.
