The program is designed to include a mandatory semester abroad, which students usually complete in the fifth (and potentially sixth) semester. The Free University offers a range of exchange opportunities with American, Canadian, and European Universities. These programs include an exemption from tuition fees at the host university. For stipends covering other expenses, students can apply to the German Academic Exchange Service, Promos, etc. See the website of the Office for International Student Mobility for further information.
In order to study in the B.A. program, applicants have to provide proof of English language proficiency at level C1 or pass an English test at the language center of Freie Universität. The next examination is scheduled for July 30, 2018. More details can be found here (German only). In case you already have an English language certificate (that must not be older than 3 years), please submit a copy of the respective certificate to the attention of email@example.com until July 15, 2018 in order to be exempted from taking the language test. For an overview of the accepted language certificates and the necessary test scores, please consult the website of the Sprachenzentrum (German only).
